  add silence gen to wait apps
  
  asterisk.conf's 'transmit_silence' option existed before
  this patch, but was limited to only generating silence
  while recording and sending DTMF.  Now enabling the
  transmit_silence option generates silence during wait
  times as well.
  
  To achieve this, ast_safe_sleep has been modified to
  generate silence anytime no other generators are present
  and transmit_silence is enabled.  Wait apps not using
  ast_safe_sleep now generate silence when transmit_silence
  is enabled as well.
