  Don't send redirecting updates to the caller if the dialplan forked the call.
  
  Each fork in the dial could be redirected and confuse the caller.  For
  ISDN the DivLeg1 and DivLeg3 messages would get confused because ISDN
  redirects calls in sequence not in parallel.
  
  * Also fixed a formatting inconsistency in app_dial.c and make a warning
  message more useful about what frame type could not be written.
