Merge bitcoin#21573: Update libsecp256k1 subtree to latest master
5c7ee1b libsecp256k1 no longer has --with-bignum= configure option (Pieter Wuille) bdca9bc Squashed 'src/secp256k1/' changes from 3967d96..efad350 (Pieter Wuille) cabb566 Disable certain false positive warnings for libsecp256k1 msvc build (Pieter Wuille) Pull request description: This updates our src/secp256k1 subtree to the latest upstream master. The changes include: * The introduction of safegcd-based modular inverses, reducing ECDSA signing time by 25%-30% and ECDSA verification time by 15%-17%. * [Original paper](https://gcd.cr.yp.to/papers.html) by Daniel J. Bernstein and Bo-Yin Yang * [Implementation](bitcoin-core/secp256k1#767) by Peter Dettman; [final](bitcoin-core/secp256k1#831) version * [Explanation](https://github.com/bitcoin-core/secp256k1/blob/master/doc/safegcd_implementation.md) of the algorithm using Python snippets * [Analysis](https://github.com/sipa/safegcd-bounds) of the maximum number of iterations the algorithm needs * [Formal proof in Coq](https://medium.com/blockstream/a-formal-proof-of-safegcd-bounds-695e1735a348) by Russell O'Connor, for a high-level equivalent algorithm * Removal of libgmp as an (optional) dependency (which wasn't used in the Bitcoin Core build) * CI changes (Travis -> Cirrus) * Build system improvements ACKs for top commit: laanwj: Tested ACK 5c7ee1b Tree-SHA512: ad8ac3746264d279556a4aa7efdde3733e114fdba8856dd53218588521f04d83950366f5c1ea8fd56329b4c7fe08eedf8e206f8f26dbe3f0f81852e138655431
