cd32a50d67 Fix NewSesssionTicket vs ChangeCipherSpec bug
Since we were cheating on state, ssl_read_record() wasn't able to drop
out-of-sequence ChangeCipherSpec messages. Cheat a bit less.

502bf30fb5 Handle reassembly of handshake messages
Works only with GnuTLS for now, OpenSSL packs other records in the same
datagram after the last fragmented one, which we don't handle yet.

Also, ssl-opt.sh fails the tests with valgrind for now: we're so slow with
valgrind that gnutls-serv retransmits some messages, and we don't handle
duplicated messages yet.
