523fb3233a Ignore PKCS1 based sig algs in TLSv1.3
In TLSv1.3 we must use PSS based sig algs for RSA signing. Ignore any
shared sig algs which are PKCS1 based.

ace081c1ed Fix client application traffic secret
A misreading of the TLS1.3 spec meant we were using the handshake hashes
up to and including the Client Finished to calculate the client
application traffic secret. We should be only use up until the Server
Finished.

536199ece0 Use NIDs instead of the old TLSv1.2 sigalgs hash and sig ids
We had an extra layer of indirection in looking up hashes and sigs based
on sigalgs which is now no longer necessary. This removes it.

703bcee021 Convert Sigalgs processing to use ints
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.

290a0419f0 Mark a HelloRequest record as read if we ignore it
Otherwise the client will try to process it again. The second time around
it will try and move the record data into handshake fragment storage and
realise that there is no data left. At that point it marks it as read
anyway. However, it is a bug that we go around the loop a second time, so
we prevent that.

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).

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.
