The attached patch adds support for Diameter conversations and Service Response
Time (Wireshark only). 

Notes:
1- For identifying a unique request-answer pair, I am currently using only the
hop_by_hop_id because these is supposed to be unique between two Diameter
agents. At the moment, there are no checks for duplicates etc. This can be
improved subsequently.

2- Conversation tracking might not work properly for SCTP multi-homed
connections.

3- The SRT dialog currently shows only one combined stat for all diameter
commands. This was OK for me and I think it is a good start. I'll try to
enchance it as time permits. There is a FIXME comment in the file should
someone else want to improve this.


The patch has been fuzz-tested with a capture containing over 1000 Diameter
requests/answers.
