As part of the SignatureAlgorithm change in the TLS 1.3 specification,
the existing signature/hash combinations are replaced with a combined
signature algorithm identifier. This change maintains the existing APIs
while fixing the internal representations. The signing code currently
still treats the SignatureAlgorithm as a decomposed value, which will be
fixed as part of a separate CL.

Now dtls1_do_handshake_write takes in a serialized form of the full message and
writes it. It's a little weird to serialize and deserialize the header a bunch,
but msg_callback requires that we keep the full one around in memory anyway.
Between that and the handshake hash definition, DTLS really wants messages to
mean the assembled header, redundancies and all, so we'll just put together
messages that way.
This also fixes a bug where ssl_do_msg_callback would get passed in garbage
where the header was supposed to be. The buffered messages get sampled before
writing the fragment rather than after.

This is the only codepath where ssl->version can get a garbage value, which is
a little concerning. Since, in all these cases, the peer is failing to connect
and speaks so low a version we don't even accept it anymore, there is probably
not much value in letting them distinguish protocol_version from a record-layer
version number mismatch, where enforced (which will give a version-related
error anyway).
Should we get a decode_error or so just before version negotiation, we'd have
this behavior already.
