Description
-------

* Fixed ast_channel_publish_dial_forward() not locking the forwarded channel when taking the channel snapshot.

* Fixed app_dial.c:do_forward() using the wrong channel to get the original call forwarding string.

* Removed unnecessary locking when calling ast_channel_publish_dial() and ast_channel_publish_dial_forward() in app_dial and app_queue.  Holding channel locks when calling ast_channel_publish_dial_forward() with a forwarded channel could result in pausing the system while the stasis bus completes processsing a forwarded channel subscription.

Testing
-------

Dialed a number that redirected the call to a new number.  Call still went were expected.


Thanks,
