[reSIProcate] new Cookie authentication scheme implemented

[Daniel Pocock]

Hi all,

Catalin is just finishing off a cookie authentication scheme in the
repro SIP proxy
https://github.com/catalinusurelu/resiprocate/tree/b-gsoc-2013

It is based on a shared-secret digest mechanism, similar to the way
tokens are constructed for e-commerce web sites.

The tokens include a timestamp to ensure SIP sessions have to be started
within a certain timeframe.

Would anybody be interested in testing this work with JsSIP perhaps?

Regards,

Daniel
