As required by RFC4492 an absent supported points format by a server is
not an error: it should be treated as equivalent to an extension only
containing uncompressed.

Don't assume a decode error if session tlsext_ecpointformatlist is not NULL: it can be legitimately set elsewhere.

Reorganise RI checking code and handle some missing cases.

server indicates RI support then renegotiation handshakes include RI.

NB: current MCSV value is bogus for testing only, will be updated when we
have an official value.

Change mismatch alerts to handshake_failure as required by spec.

Also have some debugging fprintfs so we can clearly see what is going on
if OPENSSL_RI_DEBUG is set.
