  Add flags to chanspy audiohook so that audio stays in sync.
  
  There are two flags being added to the chanspy audiohook here. One
  is the pre-existing AST_AUDIOHOOK_TRIGGER_SYNC flag. With this set,
  we ensure that the read and write slinfactories on the audiohook do
  not skew beyond a certain tolerance.
  
  In addition, there is a new audiohook flag added here,
  AST_AUDIOHOOK_SMALL_QUEUE. With this flag set, we do not allow for
  a slinfactory to build up a substantial amount of audio before 
  flushing it. For this particular issue, this means that the person 
  spying on the call will hear the conversations in real time with very 
  little delay in the audio.
