	* backends/rb-player.c: (rb_player_interface_init),
	(rb_player_open), (rb_player_close), (rb_player_play),
	(rb_player_set_replaygain), (rb_player_multiple_open),
	(rb_player_new), (_rb_player_emit_eos), (_rb_player_emit_info),
	(_rb_player_emit_buffering), (_rb_player_emit_error),
	(_rb_player_emit_tick), (_rb_player_emit_event),
	(_rb_player_emit_playing_stream):
	* backends/rb-player.h:
	* bindings/python/rb.defs:
	* lib/rb-marshal.list:
	Additions to the RBPlayer interface to support gapless and crossfading
	playback.  The caller now associates data with each stream it opens,
	which is passed back through signals.  If the backend supports it, the
	caller can open multiple streams at the same time, allowing the next
	stream to be prepared before the current stream ends.  rb_player_play
	now has a parameter that specifies what should happen to the existing
	playing stream.  The 'playing-stream' signal is emitted when the
	playing stream actually changes, so the caller doesn't have to assume
	that rb_player_play takes effect immediately.

	* shell/rb-shell-player.c: (rb_shell_player_constructor),
	(rb_shell_player_get_crossfade),
	(rb_shell_player_open_playlist_url),
	(rb_shell_player_handle_eos_unlocked),
	(rb_shell_player_handle_eos), (rb_shell_player_init),
	(open_location_thread), (rb_shell_player_open_location),
	(rb_shell_player_play), (do_next_idle),
	(rb_shell_player_set_playing_entry), (rb_shell_player_do_previous),
	(rb_shell_player_do_next_internal), (rb_shell_player_do_next),
	(rb_shell_player_play_entry), (rb_shell_player_playpause),
	(rb_shell_player_sync_replaygain),
	(rb_shell_player_entry_activated_cb),
	(rb_shell_player_property_row_activated_cb),
	(rb_shell_player_set_playing_source_internal),
	(rb_shell_player_stop), (new_playing_stream_idle_cb),
	(current_playing_stream_idle_cb), (playing_stream_cb), (error_cb),
	(tick_cb), (gconf_track_transition_time_changed),
	(gconf_track_transition_album_check_changed),
	(gconf_network_buffer_size_changed):
	Use the RhythmDBEntry as the data associated with RBPlayer streams.
	Add various checks to ignore signals from RBPlayer that don't
	correspond to the stream we think is playing.

	Update the UI when the player emits the playing-stream signal, rather
	than hoping that rb_player_play works immediately.

	Read preferences for crossfading and network buffer size from gconf.
	Provide an option to disable crossfading between tracks on the same
	album (for DJ mix/live concert cases).

	In the player tick signal handler, start crossfading or prepare for
	gapless playback when the playing stream gets within a few seconds of
	the end.  Treat this as EOS (and therefore update play statistics
	etc.) and ignore the real EOS when it arrives.

	* shell/rb-shell.c: (rb_shell_finalize),
	(rb_shell_construct_notify_titles):
	Nothing very important

	* sources/rb-streaming-source.c: (buffering_cb):
	* plugins/iradio/rb-iradio-source.c: (info_available_cb):
	Minor updates for RBPlayer interface changes

	* backends/gstreamer/Makefile.am:
	* backends/gstreamer/rb-player-gst.c: (rb_player_init),
	(tick_timeout), (emit_signal_idle), (rb_player_gst_bus_cb):
	Update the existing player backend for the RBPlayer interface changes.

	* shell/Makefile.am:
	* backends/gstreamer/rb-player-gst-xfade.c:
	* backends/gstreamer/rb-player-gst-xfade.h:
	New player backend implementing crossfading and gapless playback.

	* plugins/visualizer/rb-visualizer-plugin.c:
	(create_visualizer_element), (update_playbin_visualizer),
	(update_tee_visualizer), (update_visualizer), (impl_activate):
	Use the RBPlayerGstTee interface to implement visualization for the
	new player backend; somewhat shaky at the moment.

	* plugins/audiocd/Makefile.am:
	* plugins/audiocd/rb-audiocd-plugin.c:
	(rb_audiocd_plugin_can_reuse_stream_cb),
	(rb_audiocd_plugin_reuse_stream_cb), (impl_activate):
	Use the new player backend's can-reuse-stream and reuse-stream signals
	to skip between tracks on audio CDs rather than closing and reopening
	the device (or attempting to crossfade between tracks..)

	* data/glade/playback-prefs.glade:
	* data/rhythmbox.schemas:
	* lib/rb-preferences.h:
	* shell/rb-shell-preferences.c: (rb_shell_preferences_init),
	(rb_shell_preferences_sync), (update_playback_prefs_sensitivity),
	(rb_shell_preferences_player_backend_cb),
	(rb_shell_preferences_album_crossfade_cb),
	(rb_shell_preferences_transition_duration_cb),
	(rb_shell_preferences_network_buffer_size_cb):
	Add preferences UI for playback.

	Fixes #130426.
