In previous implements of Interoperable RA-TLS, we can only generate & verify pubkey-hash in sha-256 format. This commit brings support for verifying pubkey-hash minimal set of hash functions: sha-256 (ID 1), sha-384 (ID 7) and sha-512 (ID 8). Note that we are still only able to generate pubkey-hash in sha-256 format in RATS-TLS.
In addition, in this commit, we moved part of the code from openssl/un_negotiate.c to tls_wrapper_verify_certificate_extension.c to reduce coupling.
