Pull request description:
### Description
This also changes the code coverage front end to coveralls instead of codecov, which had some issues with other changes in the PR. This will provide better and more accurate code coverage reports.
### Notes to the reviewers
The tests run before generating the report are not exhaustive (not exhaustive earlier too, but I added as many as I could), and hence the report won't be 100% accurate.

7c57965999 Bump version before making release branch, separate patch_release template (Steve Myers)
3d69f1c291 Update DEVELOPMENT_CYCLE.md to work with [patch.crates-io] (Steve Myers)
Pull request description:
### Description
Update DEVELOPMENT_CYCLE and release instructions to make [overriding dependencies] possible for downstream projects with unreleased `bdk` versions for development and testing. Also simplifies the release process by capturing changelog information in the `pull_request_template` and recording release changelog information in the release tag message instead of in a `CHANGELOG.md` file which causes too many merge conflicts and complicates the release process.
Fixes#536Fixes#496
### Notes to the reviewers
The primary changes to our current release process are:
1. Don't add `-dev` or `-rc.x` to unreleased `bdk` cargo versions because those extensions do not work with [overriding dependencies].
2. Increment the `master` branch version as soon as a `release/MAJOR.MINOR` branch is created, the next release `release/MAJOR.MINOR` branch version with be **MAJOR.MINOR.PATCH**, and the `master` branch development version will be **MAJOR.MINOR+1.0**; either version can be used with [overriding dependencies].
4. Remove the `bdk` version from the `src/lib.rs` file so that it doesn't need to be changed on every release, because it isn't needed in the rust docs for most developers and removing it will help simplify the release process.
5. The new release process is now documented as a checklist in a new `release.md` github issue template.
6. Putting changelog information in the release tag message is how the tokio project does it. ~~After this PR is merged I will replace old tags with new ones containing changelog information and then do a new PR to remove the CHANGELOG.md file.~~ After this PR is merged I don't think we need to update old tags, only rename the CHANGELOG.md file to CHANGELOG-OLD.md with a note to check tags for future change log info.

76034772cb Add a custom signer for hardware wallets (wszdexdrf)
Pull request description:
Also adds a new test in CI for building and testing on a virtual
hardware wallet.
### Description
This PR would enable BDK users to sign transactions using a hardware wallet. It is just the beginning hence there are no complex features, but I hope not for long.
I have added a test in CI for building a ledger emulator and running the new test on it. The test is similar to the one on bitcoindevkit/rust-hwi.
### Notes to the reviewers
The PR is incomplete (and wouldn't work, as the rust-hwi in `cargo.toml` is pointing to a local crate, temporarily) as a small change is required in rust-hwi (https://github.com/bitcoindevkit/rust-hwi/pull/42).

08668ac462 Set the db sync height (rajarshimaitra)
Pull request description:
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
Fixes#719
Previously we weren't setting the db sync height in populate_test_db
macro even when current height is provided.. This creates a bug that
get_funded_wallet will return 0 balance.
This PR fixes the populate_test_db macro and updates tests which were
previously dependent on the unsynced wallet behavior.

Our costant for the P2WPKH satisfaction size was wrong: in
7ac87b8f99 we added 1 WU for the script
sig len - but actually, that's 4WU! This resulted in
P2WPKH_SATISFACTION_SIZE being equal to 109 instead of 112.
This also adds a comment for better readability.

74e2c477f1 Replace `rpc::CoreTxIter` with `list_transactions` fn. (志宇)
Pull request description:
### Description
This fixes a bug where `CoreTxIter` attempts to call `listtransactions` immediately after a tx result is filtered (instead of being returned), when in fact, the correct logic will be to pop another tx result.
The new logic also ensures that tx results are returned in chonological order. The test `test_list_transactions` verifies this. We also now ensure that `page_size` is between the range `[0 to 1000]` otherwise an error is returned.
Some needless cloning is removed from `from_config` as well as logging improvements.

ac19c19f21 New `RpcBlockchain` implementation with various fixes (志宇)
Pull request description:
Fixes#677
### Description
Unfortunately to fix all the problems, I had to do a complete re-implementation of `RpcBlockchain`.
**The new implementation fixes the following:**
* We can track more than 100 scriptPubKeys
* We can obtain more than 1000 transactions per sync
* Transaction "metadata" for already-syned transactions are updated when we introduce new scriptPubKeys
**`RpcConfig` changes:**
* Introduce `RpcSyncParams`.
* Remove `RpcConfig::skip_blocks` (this is replaced by `RpcSyncParams::start_time`).
### Notes to the reviewers
* The `RpcConfig` structure is changed. It will be good to confirm whether this is an okay change.

We were wrongly considering the sum of "effective value" (i.e. value -
fee cost) when reporting an early "insufficient funds" error in the
branch and bound coin selection.
This commit fixes essentially two issues:
- Very high fee rates could cause a panic during the i64 -> u64
conversion because we assumed the sum of effective values would never
be negative
- Since we were comparing the sum of effective values of *all* the UTXOs
(even the optional UTXOs with negative effective value) with the target
we'd like to reach, we could in some cases error and tell the user we
don't have enough funds, while in fact we do! Since we are not required
to spend any of the optional UTXOs, so we could just ignore the ones
that *cost us* money to spend and excluding them could potentially
allow us to reach the target.
There's a third issue that was present before and remains even with this
fix: when we report the "available" funds in the error, we are ignoring
UTXOs with negative effective value, so it may look like there are less
funds in the wallet than there actually are.
I don't know how to convey the right message the user: if we actually
consider them we just make the "needed" value larger and larger (which
may be confusing, because if the user asks BDK to send 10k satoshis, why
do we say that we actually need 100k?), while if we don't we could report
an incorrect "available" value.
e8df3d2d91 Consolidate `fee_amount` and `amount_needed` (Cesar Alvarez Vallero)
Pull request description:
### Description
Before this commit `fee_amount` and `amount_needed` were passed as independent
parameters. From the perspective of coin selection algorithms, they are always
used jointly for the same purpose, to create a coin selection with a total
effective value greater than it's summed values.
This commit removes the abstraction that the use of the two parameter
introduced by consolidating both into a single parameter, `target_amount`, who
carries their values added up.
Resolves: #641
### Notes to the reviewers
I just updated old tests and didn't create new ones because almost all changes
are renames and "logic changes" (like the addition of the selection fee) are
tested in the modified tests.

Pull request description:
### Description
This PR mainly fixes two bugs:
1. TXIN_BASE_WEIGHT wrongly included the `script_len` (Fixes#160)
2. We wouldn't take into account the segwit header in the fee calculation, which could have resulted in a transaction with a lower feerate than the requested one
3. In tests we used to push 108 bytes on the witness as a fake signature, but we should have pushed 106 instead
I also add a test to reproduce the conditions of #660, to check if it's solved. Turns out it's been solved already in #630, but if you're curious about what the bug was, here it is: https://github.com/bitcoindevkit/bdk/issues/660#issuecomment-1196436776

235011feef Add assertions in the FeeRate constructor (Alekos Filini)
Pull request description:
### Description
Disallow negative, NaN, infinite or subnormal fee rate values.
### Notes to the reviewers
This commit is technically an API break because it makes the `FeeRate::from_sat_per_vb` function non-const. I think it's worth it compared to the risk of having completely nonsensical fee rates (that can break the coin selection in interesting ways).
EDIT: it's also a breaking change because our code can now panic in scenarios where it didn't before. Again, I think it's worth it.

32ae95f463 Move change calculus to coin_select (Cesar Alvarez Vallero)
Pull request description:
### Description
The former way to compute and create change was inside `create_tx`, just after
performing coin selection.
It blocked the opportunity to have an "ensemble" algorithm to decide between
multiple coin selection algorithms based on a metric, like Waste.
Now, change is not created inside `coin_select` but the change amount and the
possibility to create change is decided inside the `coin_select` method. In
this way, change is associated with the coin selection algorithm that generated
it, and a method to decide between them can be implemented.
Fixes#147.

5c940c33cb Fix wallet sync not finding coins of addresses which are not cached (志宇)
Pull request description:
Fixes#521Fixes#451
^ However, only for electrum-based `Blockchain` implementations. For RPC and Compact Block Filters, syncing works differently, and so are the bugs - I have created a separate ticket for this (#677).
### Description
Previously, electrum-based blockchain implementations only synced for `scriptPubKey`s that are already cached in `Database`.
This PR introduces a feedback mechanism, that uses `stop_gap` and the difference between "current index" and "last active index" to determine whether we need to cache more `scriptPubKeys`.
The `WalletSync::wallet_setup` trait now may return an `Error::MissingCachedScripts` error which contains the number of extra `scriptPubKey`s to cache, in order to satisfy `stop_gap` for the next call.
`Wallet::sync` now calls `WalletSync` in a loop, caching in-between subsequent calls (if needed).
#### Notes to reviewers
1. The caveat to this solution is that it is not the most efficient. Every call to `WalletSync::wallet_setup` starts polling the Electrum-based server for `scriptPubKey`s starting from index 0.
However, I feel like this solution is the least "destructive" to the API of `Blockchain`. Also, once the `bdk_core` sync logic is integration, we can select specific ranges of `scriptPubKey`s to sync.
2. Also note that this PR only fixes the issue for electrum-based `Blockchain` implementations (currently `blockchain::electrum` and `blockchain::esplora` only).
3. Another thing to note is that, although `Database` assumes 1-2 keychains, the current `WalletSync` "feedback" only returns one number (which is interpreted as the larger "missing count" of the two keychains). This is done for simplicity, and because we are planning to only have one keychain per database in the future.

6db5b4a094 Introduce `get_checksum_bytes` method and improvements (志宇)
Pull request description:
### Description
`get_checksum_bytes()` returns a descriptor checksum as `[u8; 8]` instead of `String`, potentially improving performance and memory usage.
In addition to this, since descriptors only use characters that fit within a UTF-8 8-bit code unit ([US-ASCII](https://www.charset.org/charsets/us-ascii)), there is no need to use the `char` type (which is 4 bytes). This can also potentially bring in some performance and memory-usage benefits.
### Notes to the reviewers
This is useful because we will be using descriptor checksums for indexing operations in the near future (multi-descriptor wallets #486 ).

af6bde3997 Fix: Wallet sync may decrement address index (志宇)
Pull request description:
### Description
Fixes#649
It is critical to ensure `Wallet::get_address` with `AddressIndex::new` always returns a new and unused address.
This bug seems to be Electrum-specific. The fix is to check address index updates to ensure that newly suggested indexes are not smaller than indexes already in database.
### Notes to the reviewers
I have written new tests in `/testutils/blockchain_tests.rs` that tests all `Blockchain` implementations.

> address validators are supposed to be used for a slightly different thing, which is when you ask the hardware wallet to independently generate the address for a derivation index and then you compare what you see on your computer/phone with what the hardware wallet is displaying
> in the case of change addresses i agree that it's not as important (because as you said the device can just refuse to sign) but for consistency we implemented it for both external and internal addresses
> more broadly, they can be thought of as a way to get a callback every time an address is generated, which may also be useful for other things (for example when i was working on a green-compatible client written in bdk i used that feature to ping the server every time a new address was generated, because that's required in their protocol)
> that said, i think currently pretty much nobody uses them and i am myself moving away from the concept that "everything needs to happen inside bdk": currently my mindset is targeted more towards reducing complexity by breaking down individual parts and wrapping them or making them "extensible" in some way
> that is to say: if you want to verify addresses in your hardware wallet you don't necessarily need bdk to do it for you (actually, you would still have to implement the callback manually), you can just call bdk to get a new addr and then ping the device yourself. and this would allow us to reduce complexity and delete some code
> actually, here's an idea: unless somebody here is opposed to this, i can make a pr to deprecate address validators in the next (0.20) release. if after that again nobody complains we can completely remove them and point users towards different strategies to achieve the same goal

Pull request description:
### Description
With this PR we start considering how many confirmations a coinbase has. If it's not mature yet, we don't use it for building transactions.
Fixes#413
### Notes to the reviewers
This PR is based on #611, review that one before reviewing this 😄
007c5a78335a3e9f6c9c28a077793c2ba34bbb4e adds a coinbase parameter to `populate_test_db`, to specify if you want the db to be populated with immature coins. This is useful for `test_spend_coinbase`, but that's probably going to be the only use case.
I don't think it's a big deal to have a test function take an almost_always_useless parameter - it's not an exposed API, anyways. But, if you can come up with a different way of implementing `test_spend_coinbase` that doesn't require 007c5a78335a3e9f6c9c28a077793c2ba34bbb4e, even better! I looked for it for a while, but other than duplicating the whole `populate_test_db` code, which made the test way harder to comprehend, I didn't find any other way.

6a15036867 Restrict `drain_to` usage (Daniela Brozzoni)
Pull request description:
### Description
Before this commit, you could create a transaction with `drain_to` set
without specifying recipients, nor `drain_wallet`, nor `utxos`. What would
happen is that BDK would pick one input from the wallet and send
that one to `drain_to`, which is quite weird.
This PR restricts the usage of `drain_to`: if you want to use it as a
change output, you need to set recipients as well. If you want to send
a specific utxo to the `drain_to` address, you specify it through
`add_utxos`. If you want to drain the whole wallet, you set
`drain_wallet`. In any other case, if `drain_to` is set, we return a
`NoRecipients` error.

By default bdk sets the transaction's nLockTime to current_height
to prevent fee sniping.
current_height can be provided by the user through TxParams; if the user
didn't provide it, we use the last sync height, or 0 if we never synced.
Fixes https://github.com/bitcoindevkit/bdk/issues/533

Pull request description:
### Description
I'm not sure if this is needed or helpful, but this PR adds comments to describe how the `sent` and `received` fields of `TransactionDetails` are calculated.
I wasn't sure how it was done until I looked deeper into the codebase (but maybe I am too much of a beginner and this is common sense for most).

### Notes to the reviewers
#### Milestone
I'm adding this to the `0.19` milestone because now that rust-bitcoin and rust-miniscript have been released we should not waiting too long to release a version of BDK that supports the new libraries.
#### API Breaks
Since this is an API-break because of the new version of rust-bitcoin and rust-miniscript, I'm also taking the chance to update a few things in our lib that I had been thinking about for a while.
One example is the signer interface, which had that weird `sign_whole_tx()` method. This has now been removed, and the `Signer` trait replaced with `TransactionSigner` and `InputSigner`. I'm also starting to think that the signer should not only look at the psbt to figure out what to do, but ideally it should also receive some information about the descriptor (for example, the type) to simplify the code.
One option is to add an extra parameter, but that would probably only be used by our internal signers and not much else (for example, if you ask an hardware wallet to sign, it will probably already know what kind of wallet you have).
Another option is to wrap `PrivateKey` and `DescriptorXKey<ExtendedPrivKey>` which are the two internal signers we support with a struct that contains metadata about the descriptor, and then implement the signer traits on that struct. We could construct this in `Wallet::new()`, after miniscript parses the descriptor.
#### MSRV Bump
Due to the update of `rust-electrum-client`, which in turn depends on an updated `webpki`, we will have to bump our MSRV beacuse 1.46 is not supported by the new `webpki` version.

This allows the signer to know the signing context precisely without
relying on heuristics on the psbt fields.
Due to the context being static, we still have to look at the PSBT when
producing taproot signatures to determine the set of leaf hashes that
the key can sign for.

Add two new traits:
- `StatelessBlockchain` is used to tag `Blockchain`s that don't have any
wallet-specic state, i.e. they can be used as-is to sync multiple wallets.
- `BlockchainFactory` is a trait for objects that can build multiple
blockchains for different descriptors. It's implemented automatically
for every `Arc<T>` where `T` is a `StatelessBlockchain`. This allows a
piece of code that deals with multiple sub-wallets to just get a
`&B: BlockchainFactory` to sync all of them.
These new traits have been implemented for Electrum, Esplora and RPC
(the first two being stateless and the latter having a dedicated
`RpcBlockchainFactory` struct). It hasn't been implemented on the CBF
blockchain, because I don't think it would work in its current form
(it throws away old block filters, so it's hard to go back and rescan).
This is the first step for #549, as BIP47 needs to sync many different
descriptors internally.
It's also very useful for #486.

### Notes to the reviewers
Apologize in advance if the quality of this PR is too low.(I am newbie in both bitcoin wallet and rust).
While this PR seemed very straight-forward to me in the first glance, it's actually a bit more complicated than I thought as it involves calling DB get the blockheight before sorting it.
The current implementation should be pretty naive but I would like to get some opinion to see if I am heading to a right direction first before working on optimizations like
~~1. Avoiding calling DB for optional_utxos if if the amount from required_utxos are already enough.~~ Probably not worth to do such optimization to keep code simpler?

The `WalletExport` type can still be used as an alias to
`FullyNodedExport` but it has been marked as deprecated and will be
removed in the next release.
This lets us use a tuple of (generated mnemonic, optional passphrase) as
a `DerivableKey` directly, without extracting the inner mnemonic from the
`GeneratedKey` wrapper. For BIP39 keys specifically it doesn't make much
difference because the mnemonic format doesn't encode the network, but in
general this is not the case and having a consistent API will make it
harder for people to make mistakes.
To explain why we should not extract the key: some key formats (like
BIP32 extended keys) are network-specific, meaning that if somebody
tries to use a Testnet key on a Mainnet BDK wallet, it won't work.
However, when we generate a new key we would like to be able to use that
key on any network, but we need to set some kind of placeholder for the
`network` field in the structure. This is why (or at least one of the
reasons why) we wrap the key in the `GeneratedKey` struct: we keep track
of the "valid_networks" separately, which means that even if we set our
BIP32 xprv to be a "Mainnet" key, once we go try creating a wallet with
that key BDK is smart enough to understand that `GeneratedKey`s have
their own separate set of valid networks and it will use that set to
validate whether the key can be used in the wallet or not.

f2f0efc0b3 Never delete spent utxos from the database (Daniela Brozzoni)
Pull request description:
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
A `is_spent` field is added to LocalUtxo; when a txo is spent we set
this field to true instead of deleting the entire utxo from the
database.
This allows us to create txs double-spending txs already in blockchain.
Listunspent won't return spent in mempool utxos, effectively excluding them from the coin selection and balance calculation
Fixes#414
