Review request for Asterisk Developers.


Summary
-------

This changes the behavior of __login_exec to use a pthread condition to wait rather than just waiting for a lock. Using a pthread condition frees the restraint of requiring the same thread to let execution continue (by unlocking the lock), which is important as originate uses multiple threads.


This addresses bug 12269.

Testing
-------

Testing done both here and by reporters show the problem is resolved, but I wanted to make sure I'm not missing anything as changing locking can be tricky.


Thanks,

Jeff
