[OpenSIPStack] OpenSBC Shared Line Appearance Support

[<jo...@op...>]

Hi Everyone,

Shared Line Appearance is now in CVS.   You can now register multiple UA 
sharing the same Address Of Record (AOR) and let OpenSBC automatically 
fork calls.  I would appreciate bug reports if you find any.

In addition to SLA, the registrar/upper-registrar code has been fully 
re-written to take advantage of the new transaction-bypass mechanism.  
Transaction Bypass is the ability of the application layer to set its 
own handler for messages received by NIST and NICT transactions.  This 
would tremendously optimize the code which before required a session and 
session manager to handle transactions.

Cheers!

Joegen
