  Improve handling of AST_CONTROL_T38 and AST_CONTROL_T38_PARAMETERS for non-T.38-capable channels.
  
  This change allows applications that request T.38 negotiation on a channel that
  does not support it to get the proper indication that it is not supported, rather
  than thinking that negotiation was started when it was not.
