Summary:                    [patch] [regression] One-legged Transfer (INVITE /
Replaces) not working anymore
Description: 
It seems that the "One legged Transfer" (INVITE with replaces: header) is
not working anymore in newer Versions of the 1.4 Branch.
The function has been working up to Asterisk 1.4.26.3, but doesn't
starting from 1.4.27.1 (including latest stable 1.4.29 and 1.4.30-rc2).
(With exactely the same configuration.)

Scenario:
- 10013 ("Test3") calls 10012  ("Test2")
- 10014 ("Test4") tries to pick up the call
Result:
- On phone 10012, the call is ended
- 10013 seems to answer / pick up the call, but there's no connection (no
audio)
- 10014 keeps playing the Ring-back Tone

Wow, that was quick! Thanks, David!
Tested with (patched) Asterisk 1.4.29: Pickup Case works, no locks left.
Attention: I've only tested the Pickup scenario, no regular transfers!!!
If you want me to test some other cases too, I need more testing
instructions. Attended transfers using snom phones don't seem to go through
handle_request_invite().
