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.

Move state machine knowledge out of the record layer 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.

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. Perl changes reviewed by Richard Levitte.

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. Perl changes reviewed by Richard Levitte.
