Wladimir J. van der Laan 376638afcf Merge #14047: Add HKDF_HMAC256_L32 and method to negate a private key 
8794a4b3ae QA: add test for HKDF HMAC_SHA256 L32 (Jonas Schnelli)
551d489416 Add HKDF HMAC_SHA256 L=32 implementations (Jonas Schnelli)
3b64f852e4 QA: add test for CKey::Negate() (Jonas Schnelli)
463921bb64 CKey: add method to negate the key (Jonas Schnelli)

Pull request description:

  This adds a limited implementation of `HKDF` (defined by rfc5869) that supports only HMAC-SHA256  and length output of 32 bytes (will be required for v2 transport protocol).

  This PR also includes a method to negate a private key which is useful to enforce public keys starting with 0x02 (or 0x03) (a requirement for the v2 transport protocol). The new `CKey::Negate()` method is pretty much a wrapper around `secp256k1_ec_privkey_negate()`.

  Including tests.

  This is a subset of #14032 and a pre-requirement for the v2 transport protocol.

ACKs for commit 8794a4:
