	* metadata/rb-metadata.h:
	* metadata/test-metadata.c: (load_metadata_cb):
	Process GStreamer missing-plugin messages.  This requires a slightly
	newer version of GStreamer than we otherwise require, so it's
	conditional.  Missing plugin information is available to callers of
	the RBMetadata interface.

	* shell/Makefile.am:
	* lib/rb-marshal.list:
	* shell/rb-shell.c: (rb_shell_constructor):
	* shell/rb-missing-plugins.c:
	(rb_plugin_install_plugin_is_blacklisted),
	(rb_plugin_install_blacklist_plugin),
	(rb_plugin_install_context_free), (rb_plugin_install_done),
	(on_plugin_installation_done), (missing_plugins_event),
	(missing_plugins_cb), (rb_missing_plugins_init):
	* shell/rb-missing-plugins.h:
	Add some machinery for calling GStreamer plugin installation helpers
	and then retrying the original operation.

	* rhythmdb/rhythmdb-private.h:
	* rhythmdb/rhythmdb.c: (rhythmdb_class_init), (rhythmdb_init),
	(rhythmdb_shutdown), (rhythmdb_finalize), (rhythmdb_read_leave),
	(rhythmdb_process_metadata_load_real),
	(rhythmdb_missing_plugins_cb),
	(rhythmdb_missing_plugin_event_cleanup),
	(rhythmdb_process_metadata_load), (rhythmdb_process_one_event),
	(rhythmdb_execute_load):
	Add missing plugin handling for file importing.  Requires some
	interesting locking to block further import attempts while installing
	plugins.  We don't process missing plugins for files we're going to
	ignore anyway.

	Also, while the database is read-only, add write operations to a
	separate queue rather than requeueing them endlessly until the
	database is writeable again.

	* podcast/rb-podcast-manager.c: (rb_podcast_manager_class_init),
	(rb_podcast_manager_download_file_info_cb),
	(missing_plugins_retry_cb), (missing_plugins_retry_cleanup),
	(rb_podcast_manager_save_metadata), (download_progress_cb):
	Add missing plugin handling for podcast downloads.  When installation
	is complete, retry the metadata load operation.

	* backends/gstreamer/Makefile.am:
	* backends/gstreamer/rb-player-gst-xfade.c:
	(rb_player_gst_xfade_class_init), (emit_missing_plugins),
	(rb_player_gst_xfade_handle_missing_plugin_message),
	(rb_player_gst_xfade_bus_cb):
	* backends/gstreamer/rb-player-gst.c: (rb_player_gst_class_init),
	(rb_player_gst_handle_missing_plugin_message),
	(rb_player_gst_bus_cb), (rb_player_gst_sync_pipeline),
	(end_gstreamer_operation):
	* shell/rb-shell-player.c: (rb_shell_player_class_init),
	(rb_shell_player_init), (missing_plugins_retry_cb),
	(missing_plugins_retry_cleanup), (missing_plugins_cb):
	Add missing plugin handling for playback.  When GStreamer complains
	about missing plugins, stop playback, request installation, then retry
	playback when it's done.

	Fixes #338308.
