Implement this function by moving bits from glocalfileinfo.c

Browse Source 
2008-02-21  David Zeuthen  <davidz@redhat.com>

	* glocalfileinfo.c: (_g_local_file_info_get):
	* gcontenttype.c:
	(g_content_type_get_icon): Implement this function by
	moving bits from glocalfileinfo.c
	(g_content_type_get_description): Unalias before getting
	description (#517687)

	* gfile.c: (g_file_class_init),
	(g_file_query_filesystem_info_async),
	(g_file_query_filesystem_info_finish),
	(query_filesystem_info_data_free),
	(query_filesystem_info_async_thread),
	(g_file_real_query_filesystem_info_async),
	(g_file_real_query_filesystem_info_finish):
	* gfile.h: Implement async version of
	g_file_query_filesystem_info()

	* gfileinfo.h: Add new attributes for filesystem::use-preview

	* gio.symbols: Update

	* gthemedicon.c: (g_themed_icon_append_name):
	* gthemedicon.h: Add new new convenience function.

	* gunionvolumemonitor.c: (g_union_volume_monitor_dispose),
	(get_mounts), (get_volumes), (get_connected_drives),
	(get_volume_for_uuid), (get_mount_for_uuid),
	(g_union_volume_monitor_init), (populate_union_monitor),
	(g_volume_monitor_get), (_g_mount_get_for_mount_path),
	(g_volume_monitor_adopt_orphan_mount):
	* gvolumemonitor.c:
	* gvolumemonitor.h: Use recursive locks so it's safe for volume
	monitor implementations to call into the main volume monitor. Also
	separate object initialization and volume monitor initialization
	such that non-native volume monitors can properly adopt their
	mounts away.
