	* libnautilus-extensions/nautilus-audio-player.c:
	* libnautilus-extensions/nautilus-audio-player.h:
 	(player_thread),
	(nautilus_audio_player_play), (nautilus_audio_player_stop),
	(esdout_init), (esdout_write), (get_latency), (esd_stou8),
	(esd_utos16sw), (esd_utos16), (esd_16sw):
	New code to add support for an audio player thread. This is
	a first step to avoid the use of external binaries from
	within nautilus to preview audio. This will hopefully allow
	us to use a more flexible preview mechanism in the future.
	The new code currently uses the audiofile library from
	gnome cvs.

	* libnautilus-extensions/Makefile.am:
	Add new files to build.

	* src/file-manager/fm-icon-view.c: (fm_icon_view_destroy),
	(fm_icon_view_begin_loading), (play_file), (preview_audio),
	(icon_container_preview_callback), (fm_icon_view_initialize):
	Add a conditional to allow the use of the new audio preview
	code.  The conditional is currently set to use the old code,
	not the new mechanism.
