summary 
pyOpenSSL allows TLS connection bypass via unhandled callback exception in set_tlsext_servername_callback
If a user provided callback to `set_tlsext_servername_callback` raised an unhandled exception, this would result in a connection being accepted. If a user was relying on this callback for any security-sensitive behavior, this could allow bypassing it.

Unhandled exceptions now result in rejecting the connection.
