Previously, we'd omitted OpenSSL's OCSP APIs because they depend on a complex OCSP mechanism and encourage the the unreliable server behavior that hampers using OCSP stapling to fix revocation today. (OCSP responses should not be fetched on-demand on a callback. They should be managed like other server credentials and refreshed eagerly, so temporary CA outage does not translate to loss of OCSP.) But most of the APIs are byte-oriented anyway, so they're easy to support. Intentionally omit the one that takes a bunch of OCSP_RESPIDs. The callback is benign on the client (an artifact of OpenSSL reading OCSP and verifying certificates in the wrong order). On the server, it encourages unreliability, but pyOpenSSL/cryptography.io depends on this. Dcument that this is only for compatibility with legacy software. Also tweak a few things for compatilibility. cryptography.io expects SSL_CTX_set_read_ahead to return something, SSL_get_server_tmp_key's signature was wrong, and cryptography.io tries to redefine SSL_get_server_tmp_key if SSL_CTRL_GET_SERVER_TMP_KEY is missing.
