This machinery is so different between TLS and DTLS that there is no
sense in having them share structures. This switches us to maintaining
the full reassembled message in hm_fragment and get_message just lets
the caller read out of that when ready.
This removes the last direct handshake dependency on init_buf,
ssl3_hash_message.

Both DTLS and TLS still use it, but that will change in the following
commit. This also removes the handshake's knowledge of the
dtls_clear_incoming_messages function.
(It's possible we'll want to get rid of begin_handshake in favor of
allocating it lazily depending on how TLS 1.3 post-handshake messages
end up working out. But this should work for now.)

These are where the DTLS- and TLS-specific transport layer hooks will be
defined. Later we can probably move much of the implementations of these
hooks into these files so those functions can be static.
While I'm here, fix up the naming of some constants.
