Requires a refactor of the ServerHello parsing, so that we parse first and
then subsequently process. This is because the resumption information is
held in the extensions block which is parsed last - but we need to know that
information earlier.

The record layer was making decisions that should really be left to the
state machine around unexpected handshake messages that are received after
the initial handshake (i.e. renegotiation related messages). This commit
removes that code from the record layer and updates the state machine
accordingly. This simplifies the state machine and paves the way for
handling other messages post-handshake such as the NewSessionTicket in
TLSv1.3.

In TLSv1.2 an individual sig alg is represented by 1 byte for the hash
and 1 byte for the signature. In TLSv1.3 each sig alg is represented by
two bytes, where the two bytes together represent a single hash and
signature combination. This converts the internal representation of sigalgs
to use a single int for the pair, rather than a pair of bytes.

This variable represents the index of the cert within the chain, so give it
a name that better represents that.

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).

Various functions got renamed. We need to rename the error codes too.

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.
