tickit_watch_process - invoke a callback when a child process terminates

tickit_watch_process()  registers  a  callback  function  to be invoked by the toplevel event loop when a
       child process terminates. A registered callback will be invoked by a running call to  tickit_run(3).  The
       info pointer will point to a structure containing the process PID and exit status.

       If  registered  with the TICKIT_BIND_FIRST flag, the callback will be inserted at the start of the queue,
       coming before others. If not, it is appended at the end.

       If cancelled by tickit_watch_cancel(3) the callback function is invoked with  just  the  TICKIT_EV_UNBIND
       flag if it had been registered with TICKIT_BIND_UNBIND.
