[reSIProcate] Embedded headers in a SIP Uri

[Jeremy Geras]

There's an exception when the INVITE below is parsed (using the latest code).  It looks like a bug in the parsing of embedded headers in a Uri (shows up when the Request-Line is parsed).  My reading of 3261 is that "headers" in the following won't ever contain a space (unless it's escaped):

SIP-URI          =  "sip:" [ userinfo ] hostport
                    uri-parameters [ headers ]

So I think Uri.cxx:850 should be changed to the following:

pb.skipToOneOf(ParseBuffer::Whitespace);

I've updated resip/stack/test/testSipMessage.cxx with a test case for this.  I'll check in my fix to Uri.cxx if someone can confirm that it looks good.

Thanks,
Jeremy
