We remove the separate CertificateStatus message for TLSv1.3, and instead
send back the response in the appropriate Certificate message extension.

Continuing from the previous commit we also need to extend the extensions
framework to supply the Certificate we just read during parsing.

The Certificate message in TLS1.3 has an extensions block for each
Certificate. Therefore we need to extend tls_construct_extensions() to pass
in the certificate we are working on. We also pass in the position in the
chain (with 0 being the first certificate).

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indexes into the table are no longer valid.

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.

The existing code used the magic number -1 to represent the absence of
a status_type in the extension. This commit replaces it with a macro.

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.

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.
