Subject: [SIP] REFER Referred-By syntax is broken

The Referred-By syntax is badly broken. It uses commas in the middle,
not as a way to separate replications of the header and just lists a
bunch of parameters separated by spaces.

This violates the SIP extension rules, besides being a pain to parse
(since it requires a special-purpose parser just for that line). This
may be similar in some way to the WWW-Authenticate mess, but we don't
have to replicate this here...

The header should be using the normal ;parameter mechanism.
