  -----------
  Added proto function for extra conn matching.

A TCP-based protocol may export an API function for performing extra checks when comes to matching and re-using existing connections.
For now the SSL using modules (TLS & WSS) are using the function to perform SSL cert matching, to avoid re-using connections with wrong SSL certificate.
Fixes #1651
