Generic call forward api, ast_call_forward()

Browse Source 
The function ast_call_forward() forwards a call to an extension specified in an ast_channel's call_forward string.  After an ast_channel is called, if the channel's call_forward string is set this function can be used to forward the call to a new channel and terminate the original one.  I have included this api call in both channel.c's ast_request_and_dial() and res_feature.c's feature_request_and_dial().  App_dial and app_queue already contain call forward logic specific for their application and options.

(closes issue #13630)
