Summary:                    app_dial gosub does not pass back GOSUB_RETVAL
Description: 
When calling a Gosub routine (Dial with U() option) the GOSUB_RETVAL
variable is not propagated back to the calling channel.  This makes it
effectively impossible to alter the behavior of the dialplan by having the
Gosub routine set a value with the Result application.

This patch alters app_dial to check for the GOSUB_RETVAL channel variable
on the called channel (peer) and, if set, set it on the calling channel
(chan).
