0785274ca5 Fix extension for various no- options
Previously we were omitting the extension information from ext_defs if
the association no- option was defined. This doesn't work because the
indexes into the table are no longer valid.

3b58c54f26 Fix the EC point formats extension
This should be sent in the ServerHello if a EC based ciphersuite is
negotiated. The relevant flag to do this was missed off in the recent
extensions refactor.

70af3d8ed7 Avoid repeatedly scanning the list of extensions
Because extensions were keyed by type which is sparse, we were continually
scanning the list to find the one we wanted. The way we stored them also
had the side effect that we were running initialisers/finalisers in a
different oder to the parsers. In this commit we change things so that we
instead key on an index value for each extension.

6b473acabd Refactor ClientHello extension parsing
This builds on the work started in 1ab3836b3 and extends is so that
each extension has its own identified parsing functions, as well as an
allowed context identifying which messages and protocols it is relevant for.
Subsequent commits will do a similar job for the ServerHello extensions.
This will enable us to have common functions for processing extension blocks
no matter which of the multiple messages they are received from. In TLSv1.3
a number of different messages have extension blocks, and some extensions
have moved from one message to another when compared to TLSv1.2.
