Add a TLS version consistency check during session resumption

This is a temporary fix for while we are still using the old session
resumption logic in the TLSv1.3 code. Due to differences in EXTMS support
we can't resume a <=TLSv1.2 session in a TLSv1.3 connection (the EXTMS
consistency check causes the connection to abort). This causes test
failures.

Ultimately we will rewrite the session resumption logic for TLSv1.3 so this
problem will go away. But until then we need a quick fix to keep the tests
happy.

Rename the Elliptic Curves extension to supported_groups

This is a skin deep change, which simply renames most places where we talk
about curves in a TLS context to groups. This is because TLS1.3 has renamed
the extension, and it can now include DH groups too. We still only support
curves, but this rename should pave the way for a future extension for DH
groups.

Includes addition of the various options to s_server/s_client. Also adds

This isn't "real" TLS1.3!! It's identical to TLS1.2 apart from the protocol
and the ciphersuite...and the ciphersuite is just a renamed TLS1.2 one (not
a "real" TLS1.3 ciphersuite).

A client can send a session id that's shorter, and the callback could also
