  Fix playback failure when using IAX with the timerfd module.
  
  To fix this issue the alert pipe will now be used when the timerfd
module is
  in use. There appeared to be a race that was not solved by adding
locking in the
  timerfd module, but needed to be there anyway. The race was between the
timer
  being put in non-continuous mode in ast_read on the channel thread and
the IAX 
  frame scheduler queuing a frame which would enable continuous mode
before the
  non-continuous mode event was read. This race for now is simply avoided.

  I put tested by tpanton because it was tested on his hardware. Thanks
for the
  remote access to debug this issue!
