mbedtls/library
History
Hanno Becker b03f88f06c Introduce helper for handling of post-handshake handshake messages 
Handling the receipt of a handshake record after the initial handshake
requires non-trivial logic depending on the protocol version and the
endpoint. This logic is currently embedded in mbedtls_ssl_read().

With the introduction of support for [D]TLS 1.3, the logic will become
even more complex, since [D]TLS 1.3 drops support for renegotiation --
which in [D]TLS 1.2 is the main purpose of post-handshake handshake
messages -- but instead introduces numerous other post-handshake
handshake messages.

In order to pave the way for those changes, this commit improves
readability and maintainability of mbedtls_ssl_read() by moving
the TLS <=1.2 logic for handling post-handshake handshake messages
into a separate helper function ssl_handle_hs_message_post_handshake().

The logic of the code is entirely unchanged.
