Summary:                    [patch] Dial()'s do_forward() breaks Local/ channel
frame forwarding
Description: 
This was spotted due to an issue that is caused with CDR records of calls
redirected via a SIP 302 message. The dstchannel is recorded incorrectly.


In chan_local:local_queue_frame(), there is a test to see whether
there is a channel or app to forward data to before frames are passed
on:

               if (other->pbx || other->_bridge ||
!ast_strlen_zero(other->appl)) {
                       ast_queue_frame(other, f);
               }

For a call that is being dialled, there is no pbx or bridge object, so
chan_local will only forward data if 'appl' is correctly set.

In app_dial:do_forward(), the original channel is replaced with a new
"forward" channel, but 'appl' is never set on this channel - The
effectively kills frame passing on the new Local/ channel created by
do_forward, and it stays that way until it is optimized away.
