[pjsip] pjsip-2.0-beta released!

[Nanang Izzuddin]

Hi all,

The beta version of the upcoming 2.0 version has been released on
2011/12/29 (yes, this is late announcement, sorry for that).

Updating to this version is highly recommended. Lots of enhancement
and bug fixes have been done as usual. Also some API changes
especially on video have been carried out, however by that, we hope
such API changes on the next release can be avoided.
