We haven't implemented RFC 7250 yet, although I added the
CertificateType enumeration to Java version a while back, and it's on my
list of nice-to-have TLS extensions (leading to Cache Info support) that
nobody has asked for (until now).

Extension negotiation itself can be done without needing any changes to
the library itself, but this is one of those cases where the library
needs to be "extension-aware" since it affects the parsing of the
Certificate messages. Possibly we need to reorganise things a bit so
that the core library is completely agnostic about certificate formats
and delegates all certificate processing to the peer objects
(TlsClient/TlsServer), with useful defaults of course.

Pete Dettman
