/* Extension context codes */
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.

Move init of the WPACKET into write_state_machine() Instead of initialising, finishing and cleaning up the WPACKET in every message construction function, we should do it once in write_state_machine(). Reviewed-by: Rich Salz <rsalz@openssl.org>

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.
