463921bb649d644f79f9d7f0f96f10aa0d165f76 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.
