ssl: unify common Hello dissection to ssl-utils
Based on DTLS code with changes merged from SSL. Changes:
- Ignore large Session IDs, this was not harmful though since the
backing storage was 256 bytes in size.
- {ssl,dtls}.handshake.random: fixed description, it is not used like
a SSLv2 random challenge.
- dtls: also debug print client/server for random
- SSL: the common dissector now returns an offset rather than dissected
length.
- dtls: display actual Session ID bytes in the UI rather than the text
"Session ID (32 bytes)". The length field is already visible in the
preceding field.
Also changed is the handling of key material generation. The SSL
dissector previously generated key material based on the Session ID,
Session Ticket or a key logfile. (DTLS did not have this functionality.)
As decryption is needed only after ChangeCipherSpec, I have removed it
from the ServerHello handling. This will break decryption when a
ClientKeyExchange message is missing, but it will be restored proper in
a next patch.
(By the way, there was an inverted if-condition bug in DTLS that could
break decryption by not restoring the master key matching a SID. This
is gone in the refactoring because the faulty code is removed.)
