	GIO port, 6+ months in the making.
	magnatune and jamendo plugins still need to be ported, and something
	still needs to happen with the mtp plugin too.

	* configure.ac:
	* backends/gstreamer/Makefile.am:
	* lib/Makefile.am:
	Increase required versions of glib and nautilus-cd-burner (for gio),
	and libsoup and gstreamer.  Drop howl mdns support.

	* lib/gsequence.c:
	* lib/gsequence.h:
	* shell/rb-history.c:
	* rhythmdb/rhythmdb-property-model.c:
	* rhythmdb/rhythmdb-query-model.c:
	Drop our internal copy of gsequence.  It was added to glib in 2.14, we
	require 2.16 now.

	* shell/Makefile.am:
	* backends/rb-player.c: (rb_player_new):
	* backends/gstreamer/rb-player-gst-xfade.c:
	(rb_player_gst_xfade_class_init),
	(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):
	Always compile in the crossfading player backend and GStreamer missing
	plugin support.

	* lib/rb-proxy-config.c: (rb_proxy_config_get_libsoup_uri):
	* lib/rb-proxy-config.h:
	* lib/rb-soup-compat.h:
	Drop libsoup 2.2.

	* backends/gstreamer/rb-encoder-gst.c:
	(rb_encoder_gst_emit_completed), (new_decoded_pad_cb),
	(prompt_for_overwrite), (attach_output_pipeline),
	(rb_encoder_gst_encode):
	Where possible, use giostreamsink.  When creating the output stream,
	prompt for overwriting if the target file already exists.  If
	giostreamsink can't write to the target location, use whatever sink
	gstreamer wants to use, without the overwrite prompt.

	* lib/eel-gconf-extensions.c:
	* lib/rb-file-helpers.c:
	* lib/rb-file-helpers.h:
	* lib/rb-util.c:
	* lib/rb-util.h:
	Rewrite file helper functions using gio, dropping some we don't need
	any more (rb_uri_resolve_relative, mostly).  rb_uri_handle_recursively
	and rb_uri_handle_recursively_async are now mostly our own
	implementation, as gio doesn't provide anything like these functions.
	Add some functions to check for free space on the drive containing a
	directory, and something like g_file_make_directory_with_parents.

	Leave URI canonicalisation up to gio entirely - just create a GFile
	from the URI (or whatever) and extract the URI from it.

	* metadata/rb-metadata-dbus-service.c: (main):
	* metadata/rb-metadata-gst.c: (rb_metadata_init),
	(make_undecodable_error), (rb_metadata_gst_unknown_type_cb),
	(rb_metadata_handle_missing_plugin_message),
	(rb_metadata_bus_handler), (rb_metadata_load), (rb_metadata_save),
	(rb_metadata_has_missing_plugins),
	(rb_metadata_get_missing_plugins):
	* metadata/rb-metadata.h:
	Remove gnome-vfs and gnome-authentication calls, remove #ifdefs for
	missing plugin support, and use giostreamsink to create temporary
	tag-writing output files and rename them over the original file.

	* plugins/Makefile.am:
	* plugins/audiocd/rb-audiocd-plugin.c:
	* plugins/audiocd/rb-audiocd-source.c:
	* plugins/audiocd/rb-audiocd-source.h:
	* plugins/audiocd/sj-metadata-musicbrainz.c:
	Instead of nautilus-cd-burner, ask HAL to identify audio CDs for us.
	n-c-b wasn't really helping us much here.

	* plugins/audioscrobbler/rb-audioscrobbler-entry.c:
	* plugins/audioscrobbler/rb-audioscrobbler-entry.h:
	* plugins/audioscrobbler/rb-audioscrobbler.c:
	* plugins/audioscrobbler/rb-lastfm-source.c:
	Drop libsoup 2.2 compatibility, use gio to load and save the queue
	file.

	* plugins/cd-recorder/rb-cd-recorder-plugin.c:
	* plugins/cd-recorder/rb-playlist-source-recorder.c:
	* plugins/cd-recorder/rb-recorder-gst.c:
	Drop heaps of #ifdefs for old n-c-b versions, move free space checks
	to rb-util.

	* plugins/daap/Makefile.am:
	* plugins/daap/rb-daap-connection.c:
	* plugins/daap/rb-daap-plugin.c:
	* plugins/daap/rb-daap-share.c:
	* plugins/daap/rb-daap-src.c:
	* plugins/daap/rb-daap-mdns-browser-howl.c:
	* plugins/daap/rb-daap-mdns-publisher-howl.c:
	Drop howl mdns and libsoup 2.2 support.  Use gio to send files to
	clients.

	* plugins/generic-player/rb-generic-player-playlist-source.c:
	* plugins/generic-player/rb-generic-player-plugin.c:
	* plugins/generic-player/rb-generic-player-source.c:
	* plugins/generic-player/rb-generic-player-source.h:
	* plugins/generic-player/rb-nokia770-source.c:
	* plugins/generic-player/rb-nokia770-source.h:
	* plugins/generic-player/rb-psp-source.c:
	* plugins/generic-player/rb-psp-source.h:
	Rewrite all file handling code with gio, create sources based off
	GMounts.  Probably not using the right drive/volume name yet.
	PSP and nokia770 sources are completely untested.

	* plugins/ipod/rb-ipod-db.c:
	* plugins/ipod/rb-ipod-db.h:
	* plugins/ipod/rb-ipod-plugin.c:
	* plugins/ipod/rb-ipod-source.c:
	* plugins/ipod/rb-ipod-source.h:
	Rewrite file/path handling code with gio.

	* plugins/iradio/rb-iradio-source.c:
	* plugins/iradio/rb-station-properties-dialog.c:
	Use gio URI/file functions, replace gnome_vfs_uri_list_parse with
	rb_uri_list_parse.

	* plugins/magnatune/magnatune/BuyAlbumHandler.py:
	* plugins/magnatune/magnatune/__init__.py:
	Remove unnecessary gnomevfs imports

	* plugins/mtpdevice/rb-mtp-plugin.c:
	* plugins/mtpdevice/rb-mtp-source.c:
	Rewrite some file handling code using gio, use new free space checking
	function in rb-file-helpers.

	* plugins/rb-plugins-engine.c:
	Rewrite plugin scanning code with gio.

	* plugins/rb/Loader.py:
	Add a gio loader implementation that probably doesn't work, drop the
	urllib implementation (we'll require a new enough version of pygobject
	to allow us to just use the gio implementation soon)

	* podcast/rb-feed-podcast-properties-dialog.c:
	* podcast/rb-podcast-manager.c:
	* podcast/rb-podcast-parse.c:
	* podcast/rb-podcast-properties-dialog.c:
	* podcast/test-podcast-parse.c: (main):
	gio doesn't provide anything like gnome_vfs_async_xfer (thankfully!),
	so add our own simple download thread.  Implement simple easily-fooled
	download resume by seeking to an offset equal to the current size of
	the local file.  Rewrite content type checking and URI display code
	with gio.

	* remote/dbus/Makefile.am:
	* remote/dbus/rb-client.c: (main):
	Remove glib version checks, rewrite argument handling using gio.

	* rhythmdb/rhythmdb-import-job.c:
	Update for rb_uri_handle_recursively_async changes, use a GCancellable
	to cancel the import.
	
	* rhythmdb/rhythmdb-monitor.c:
	Use gio file/directory monitoring.  Not quite using it fully yet -
	G_FILE_MONITOR_EVENT_CHANGES_DONE_HINT is probably useful.

	* rhythmdb/rhythmdb-tree.c:
	Bump database format number, as URIs need to be canonicalised yet
	again.  Use a GCancellable to cancel loading.

	* rhythmdb/Makefile.am:
	* rhythmdb/rhythmdb-private.h:
	* lib/rb-marshal.list:
	* rhythmdb/rhythmdb.c:
	* rhythmdb/rhythmdb.h:
	gio doesn't have a 'stat 10000 files' function, so implement it ourselves
	with a thread.  Attempt to mount volumes as required, emitting a
	signal to create a mount operation (rhythmdb theoretically shouldn't
	use gtk).  Move directory recursion into the action thread, rather
	than creating a new thread each time.  Use GSlice to allocate
	RhythmDBEvent and RhythmDBAction structures; we often have quite a lot
	of them.  Remove the gnome-vfs trash code, leaving the gio code added
	before 0.11.5.

	* shell/main.c: (main), (load_uri_args):
	Remove gnome authentication manager calls.  Use gio to process
	commandline args.

	* shell/rb-missing-plugins.c: (rb_missing_plugins_init):
	* shell/rb-playlist-manager.c:
	* shell/rb-shell-player.c: (rb_shell_player_class_init),
	(volume_pre_unmount_cb), (rb_shell_player_init),
	(missing_plugins_cb):
	* shell/rb-shell-preferences.c: (help_cb),
	(rb_shell_preferences_init), (rb_shell_preferences_sync):
	* shell/rb-shell.c: (rb_shell_create_mount_op_cb), (construct_db),
	(rb_shell_cmd_contents), (rb_shell_load_uri):
	* shell/rb-tray-icon.c: (rb_tray_icon_drop_cb):
	Various bits of rewriting for gio.  With new enough gtk+, use
	gtk_show_uri to display help rather than gnome_help_display, and
	create gtk mount operations when requested by rhythmdb.

	* bindings/python/rb.override:
	* shell/rb-removable-media-manager.c:
	* shell/rb-removable-media-manager.h:
	* sources/rb-removable-media-source.c:
	Use gio's drive/volume/mount monitor.  Handle both mounts and volumes
	because in some cases (audio CDs, mostly) we don't require the volume
	to be mounted, but mostly we do.  If a source is created for a volume,
	don't allow one to be created for the corresponding mount, and vice
	versa.  When asked to 'eject', first try ejecting the volume, then the
	mount, and then unmount instead.  If eject or unmount fails, don't
	remove the corresponding source.

	* sources/rb-auto-playlist-source.c:
	* sources/rb-browser-source.c:
	* sources/rb-library-source.c:
	* sources/rb-play-queue-source.c:
	* sources/rb-playlist-source.c:
	* sources/rb-podcast-source.c:
	* sources/rb-static-playlist-source.c:
	Rewrite file handling, URI formatting, list parsing, etc. code with
	gio equivalents.

	* widgets/rb-entry-view.c: (rb_entry_view_location_cell_data_func):
	* widgets/rb-entry-view.h:
	* widgets/rb-property-view.c:
	* widgets/rb-query-creator-properties.c:
	(escapedStringCriteriaSetWidgetData),
	(escapedStringCriteriaGetWidgetData):
	* widgets/rb-song-info.c: (rb_song_info_update_filesize),
	(rb_song_info_update_location):
	* widgets/rb-uri-dialog.c:
	Replace gnome-vfs URI formatting and unescaping functions with gio
	equivalents.

	* tests/bench-rhythmdb-load.c: (main):
	* tests/test-audioscrobbler.c: (START_TEST):
	* tests/test-file-helpers.c: (main):
	* tests/test-rhythmdb-property-model.c: (main):
	* tests/test-rhythmdb-query-model.c: (main):
	* tests/test-rhythmdb.c: (main):
	Update test programs, mostly removing gnome_vfs_init() and
	gnome_vfs_shutdown().

	* lib/rb-debug.c: (rb_debug_init_match):
	Add gio log domain to the set we handle to interrupt debuggers.

	From #510392, fixes #319758.
