* libnautilus-extensions/nautilus-directory.c:
	(nautilus_directory_notify_files_removed,
	nautilus_directory_notify_files_moved): Use
	`nautilus_file_get_existing', not `nautilus_file_get', to check if
	a file is already known. `nautilus_file_get' would have created
	new NautilusFiles and NautilusDirectories only to do redundant
	notification later in the function. Also, the old code was a bit
	silly because `nautilus_file_get' only returns NULL for a NULL
	URI.

	Work towards bug 3362, eliminate directory metadata.

	* libnautilus-extensions/nautilus-file-attributes.h: Added
	NAUTILUS_FILE_ATTRIBUTE_METADATA attribute.

	* libnautilus-extensions/nautilus-directory-async.c
	(set_up_request_by_file_attributes):

	* libnautilus-extensions/nautilus-wait-until-ready.h,

	nautilus_directory_file_monitor_add,
	nautilus_self_check_directory, nautilus_file_monitor_add,
	nautilus_file_call_when_ready, nautilus_file_wait_until_ready):
	Remove monitor_metadata or wait_for_metadata attribtues from these
	calls; the new way to do it is to monitor or wait for the METADATA
	file attribute.

	* libnautilus-extensions/nautilus-directory-private.h
	libnautilus-extensions/nautilus-directory-async.c:
	(nautilus_directory_monitor_add_internal,
	nautilus_directory_call_when_ready_internal,
	nautilus_directory_check_if_ready_internal): Eliminate
	monitor_metadata, wait_for_metadata, etc arguments.

	* libnautilus-extensions/nautilus-merged-directory.c:
	(merged_callback_connect_directory), (merged_call_when_ready),
	(merged_file_monitor_add), (monitor_add_directory):

	(vfs_call_when_ready), (vfs_file_monitor_add):

	* libnautilus-extensions/nautilus-directory-background.c
	(nautilus_connect_background_to_directory_metadata): Monitor
	metadata the new approved way.

	* libnautilus-extensions/nautilus-mime-actions.c
	(nautilus_directory_wait_for_metadata,
	nautilus_mime_get_default_component_for_uri_internal,
	nautilus_mime_get_short_list_components_for_uri,
	nautilus_mime_get_all_components_for_uri,
	get_mime_type_from_file): Wait for metadata the new approved way.

	* src/file-manager/fm-directory-view.c
	(fm_directory_view_activate_file, fm_directory_view_load_uri,
	finish_loading_uri, metadata_ready_callback):
	Monitor/call_when_ready using the new API.

	* src/file-manager/fm-properties-window.c:
	(create_properties_window, fm_properties_window_present):
	Monitor/call_when_ready using the new API.

	* src/file-manager/fm-search-list-view.c (real_adding_file):
	Monitor/call_when_ready using the new API.

	* src/file-manager/nautilus-trash-monitor.c
	(nautilus_trash_monitor_initialize): Monitor/call_when_ready using
	the new API.

	* src/nautilus-applicable-views.c (nautilus_navigation_info_new):

	nautilus_sidebar_add_panel_items,
	nautilus_sidebar_background_is_default, receive_dropped_uri_list,

	background_appearance_changed_callback, background_reset_callback,
	open_with_callback, nautilus_sidebar_update_buttons,
	nautilus_sidebar_update_appearance, nautilus_sidebar_set_uri):
	Monitor/call_when_ready using the new API, and use file metadata
	instead of directory metadata. Keep around a NautilusFile
	representing the current sidebar location, simplifying bunches of
	code and hopefully eliminating potential redundant I/O.

	* src/nautilus-window-manage-views.c
	(viewed_file_changed_callback, position_and_show_window_callback,
	nautilus_window_end_location_change_callback):
	Monitor/call_when_ready using the new API, and use file metadata
