  Assist proper thread synchronization when stopping the logger thread.
  
  I was finding that on my dev box, occasionally attempting to "stop now" in
  trunk would cause Asterisk to hang. I traced this to the fact that the logger
  thread was waiting on a condition which had already been signalled. The logger
  thread also need to be sure to check the value of the close_logger_thread variable.
  
  The close_logger_thread variable is only checked when the list of logmessages is empty.
  This allows for the logger thread to print and free any pending messages before exiting.
