aa39a0557c kqueue: Multiple fixes and simplifications
- Stop using a custom thread for listening to kqueue(2) events.  Instead
   call kevent(2) in non blocking mode in a monitor callback.  Under the
   hood poll(2) is used to figure out if new events are available.

 - Do not use a socketpair with a custom protocol requiring 2 supplementary
   context switches per event to commicate between multiple threads.  Calling
   kevent(2), in non blocking mode, to add/remove events is fine from any
   context.

 - Add kqueue(2) events without the EV_ONESHOT flag.  This removes a race
   where some notifications were lost because events had to be re-added for
   every new notification.

 - Get rid of the global hash table and its associated lock and races.  Use
   the 'cookie' argument of kevent(2) to pass the associated descriptor when
   registering an event.

 - Fix _kh_file_appeared_cb() by properly passing a monitor instead of a
   source to g_file_monitor_emit_event().

 - Properly refcount sources.

 - Remove a lot of abstraction making it harder to fix the remaining issues.

9e8f4d4736 kqueue: add a bit of extra paranoia on cancel
Cancellation of GPollFileMonitor is now handled correctly (in the sense
that no further signals will follow) but let's be extra paranoid and
disconnect our handler anyway, for good measure.

641b98ce6b kqueue backend: port to new GLocalFileMonitor API
This is the bare minimal effort.  This seems not to crash immediately,
but it definitely needs some better testing.

The backend is not in good shape.  It could use some serious work.

a335fd1de8 GFileMonitor: Add kqueue(3) support to GIO
Written by Dmitry Matveev as part of GSoC 2011:
http://netbsd-soc.sourceforge.net/projects/kqueue4gio/

This brings native file monitoring support on systems supporting kqueue(3)
(all BSDs) and remove the need to rely on the unmaintained gamin software.
The backend adds GKqueueDirectoryMonitor and GKqueueFileMonitor.

Some parts rewritten by myself (to prevent needing a configuration file).
Helpful inputs from Colin Walters and Simon McVittie.
