Issue #12551: Provide a get_channel_binding() method on SSL sockets so as
to get channel binding data for the current SSL session (only the
"tls-unique" channel binding is implemented).  This allows the
implementation of certain authentication mechanisms such as SCRAM-SHA-1-PLUS.

Patch by Jacek Konieczny.
