Summary:                    [patch] SIP Forking Feature
Description: 
This feature enables a user to register from multiple locations and there
by allows forking of a SIP call.

Registration entries are maintained as a list in peers.
Registration refreshes of the same user are checked and updated
accordingly. New registrations of the same user from different location
will be added as a list in sip_peer structure.

An outgoing call is checked against the number of peers registered from
peer list and the invite is forked to all the location from where the user
is registered. Only the fisrst successful 2xx will establish a call, and
other forked calls will be terminated.

Thanks for the update.

My idea was from SIP point of view, as this is specific to SIP (dont know
whether other channels drivers support it) and also as the forking needs to
be done for a 'single' user registered from multiple locations, unlike
wherein PBX layer the call is forked to 'different' users, i thought it
would be better to handle at SIP channel driver

But these are valuable comments and let me see how best it can be
implemented at pbx layer
