[reSIProcate] Via Branches: format change, cookie change.


As part of the SigComp integration, I updated the Via header field branch parameter, since I need to squirrel away information on a per-transaction basis, and I need to get to it down in the transports (before transaction correlation is performed).

Scott Godin discovered that this change leads to incompatibilities when running an older resip client against a newer resip proxy. I've fixed this problem by changing the resip cookie from -d87543- to -d8754z-.

I don't suspect anyone really cares about this change, but it seemed fundamental enough that I wanted to put it on the list so that any objections can be raised.
