2022917223Add secp256k1_selftest call (Pieter Wuille)3bfca788b0Remove explicit enabling of default modules (Pieter Wuille)4462cb0498Adapt to libsecp256k1 API changes (Pieter Wuille)9d47e7b71bSquashed 'src/secp256k1/' changes from 44c2452fd3..21ffe4b22a (Pieter Wuille) Pull request description: Now that libsecp256k1 has a release (https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-December/021271.html), update the subtree to match it. The changes themselves are not very impactful for Bitcoin Core, but include: * It's no longer needed to specify whether contexts are for signing or verification or both (all contexts support everything), so make use of that in this PR. * Verification operations can use the static context now, removing the need for some infrastructure in pubkey.cpp to make sure a context exists. * Most modules are now enabled by default, so we can drop explicit enabling for them. * CI improvements (in particular, MSVC and more recent MacOS) * Introduction of an internal int128 type, which has no effect for GCC/Clang builds, but enables 128-bit multiplication in MSVC, giving a ~20% speedup there (but still slower than GCC/Clang). * Release process changes (process documentation, changelog, ...).
