	* acinclude.m4(BM_THUNAR_VFS_VOLUME_IMPL): Handle "none" properly.
	* thunar-vfs/thunar-vfs-volume-manager.c, thunar-vfs/Makefile.am,
	  thunar-vfs/thunar-vfs-volume-private.h, thunar-vfs/thunar-vfs.symbols,
	  thunar-vfs/thunar-vfs-volume.c, thunar-vfs/thunar-vfs-volume-none.c,
	  thunar-vfs/thunar-vfs-volume.h, thunar-vfs/thunar-vfs-volume-hal.c,
	  thunar-vfs/thunar-vfs-volume-freebsd.c: Improve the volume manager
	  implemenation. The ThunarVfsVolumeManager and ThunarVfsVolume inter-
	  faces are now abstract base classes, with the implementation API
	  completely separated from the public API. The HAL backend was fixed
	  to work around a strange HAL bug, where 'volume.is_mounted' is FALSE
	  for mounted volumes (instead of trusting HAL, we ask the kernel to
	  make sure we always display the proper state). Also, new signals
	  "mounted", "pre-unmount" and "unmounted" were added to both
	  ThunarVfsVolume and ThunarVfsVolumeManager, to allow applications to
	  perform certain actions for these events.
	* docs/reference/thunar-vfs/: Update the API documentation.
	* thunar/thunar-window.c: Whenever the user requests to unmount a
	  volume, check if the window displays a folder on this volume and if
	  so, go to the home folder, to make sure we don't display a probably
	  no longer existing mount point afterwards.
