Also add a specific test that fails adaptor sig deserialization because with the
correct size buffer that's not guaranteed anymore with the existing test.
Previously the ECDSA signature had an overflowing s value, which after the sync
with upstream results in a failing VERIFY_CHECK in the inversion function.
However, normally parsed signatures shouldn't contain overflowing s values.
This reverts commit 20448b8d09.
The removed functions secp256k1_ge_set_xquad and secp256k1_fe_is_quad_var
are required for some modules in secp256k1-zkp.

Pull request description:
I was trying to determine the impact of ecmult_gen in schnorrsig signing and noticed that there is no way to bench this right now. The new benchmarks look like this:
```
$ ./bench_ecmult
ecmult_gen: min 20.9us / avg 21.2us / max 21.7us
ecmult_const: min 63.9us / avg 64.3us / max 64.8us
ecmult 1: min 49.4us / avg 49.7us / max 50.3us
ecmult 1g: min 39.8us / avg 40.0us / max 40.3us
ecmult 2g: min 27.2us / avg 27.3us / max 27.8us
ecmult_multi 1g: min 39.8us / avg 40.0us / max 40.2us
ecmult_multi 2g: min 27.2us / avg 27.4us / max 27.7us
ecmult_multi 3g: min 22.8us / avg 22.9us / max 23.1us
ecmult_multi 4g: min 20.6us / avg 20.8us / max 21.1us
ecmult_multi 5g: min 19.3us / avg 19.5us / max 19.7us
```
(Turns out ecmult_gen is 37% of the 55.8us that schnorrsig sign takes)

This removes the ununsed `obj` directory. It also suggests in the README
to create the "coverage" files in a separate directory and adds the

0881633dfd secp256k1.h: clarify that by default arguments must be != NULL (Jonas Nick)
Pull request description:
The same file says that the illegal callback will only triger for violations
explicitly mentioned, which is not true without this commit because we often
don't mention that an argument is not allowed to be NULL.
This line is extracted from #783 in the hope that it gets merged faster because other PRs depend on it.
