  Made Dial d and H options no longer immediately auto-answer the calling leg.
  
  The Dial d and H options break DTMF attended transfer atxferdropcall
  option.
  
  1) Party A calls party B.
  2) Party B does a DTMF attended transfer to Party C.
  
  If the dialplan uses the Dial d or H options to call Party C then the Dial
  application answers the call immediately before initiating the call leg to
  Party C.  The premature answer causes the transfer code to not invoke the
  atxferdropcall=no behavior for a blonde transfer since Party C has
  "answered".  The transfer code thinks that Party B has "consulted" with
  Party C when Party B hangs up and completes the transfer to Party A.
  Party A now hears ringback until Party C actually answers.
  
  ASTERISK-13294 Dial d option.
  ASTERISK-11067 Dial H option to disconnect before answer.
  
  The referenced issues made Dial answer with the d and H options because
  many SIP and ISDN phones cannot send DTMF before the call is connected.
  
  * Made require the dialplan to control when or if the call needs to be
  answered to use the Dial application d and H options.  (The call is no
  longer surprise answered when using the Dial d or H options.)

 * The outgoing directory (where .call files are read) now uses inotify to

   If your outgoing folder is on a NFS mount or another network file system,
