* thunar/thunar-local-file.h: Add missing THUNAR_LOCAL_FILE_GET_CLASS().
	* configure.in.in: Add checks for kqueue() and required headers.
	* thunar-vfs/thunar-vfs-info.{c,h}: thunar_vfs_info_update() is now
	  part of the public API as it's used by monitor and will be used
	  by the ThunarLocalFile implementation later as well.
	* thunar-vfs/thunar-vfs-monitor.{c,h}: Add implementation for most
	  of the ThunarVfsMonitor. The current implementation uses kqueue()
	  if available with a fallback to regular polling.
