DTLS: add DSB support, use the key log file from the TLS dissector
The DTLS and TLS dissectors already share code for parsing the key log
file contents but the actual key material was stored separately. As
implementations (like GnuTLS) write the TLS and DTLS secrets to the same
file (specified by the SSLKEYLOGFILE environment variable), it seems
reasonable to combine them.
This also enables use of the pcapng Decryption Secrets Block for
decryption of DTLS traces. The dtls.keylog_file preference has become
obsolete and can no longer be used (this was not tested anyway).
A new test was added based on dtls12-aes128ccm8.pcap, the master secret
was extracted using the tls.debug_file preference.
