More prep work for the trash directory.

	* libnautilus-extensions/Makefile.am:
	* libnautilus-extensions/nautilus-trash-directory.c:

	(nautilus_vfs_directory_initialize),
	(nautilus_vfs_directory_destroy):
	* libnautilus-extensions/nautilus-vfs-directory.h:
	Add subclasses for the trash and for general VFS directories.
	Using refactoring techniques to move code down into these
	subclasses. This is not intended to be a general framework,
	but should be good enough to handle both these cases.

	* libnautilus-extensions/nautilus-directory-async.c:
	(can_use_public_metafile), (metafile_read_check_for_directory),
	(metafile_read_failed), (metafile_read_start), (allow_metafile),

	(nautilus_file_mark_gone), (nautilus_file_changed):
	* libnautilus-extensions/nautilus-file.h:
	Add code to handle case of directory that can't be handled by
	gnome-vfs. Mostly some NULL checks. Also renamed fields to make
	it clear that the text URI is the "real" one. Added code to
	handle the "gnome-trash:" and "trash:" schemes specially in the
	code to make URIs canonical.

	* libnautilus-extensions/nautilus-mime-actions.c:
	(get_mime_type_from_uri): Return "application/octet-stream"
	instead of NULL for unknown MIME type.

	* src/file-manager/fm-directory-view.c:
	(fm_directory_view_display_selection_info): Eliminated the
	nautilus_file_get_real_name call.
	* src/nautilus-switchable-navigation-bar.c:
	(nautilus_switchable_navigation_bar_set_location): Eliminated
	the nautilus_directory_is_search_directory call.

	* src/file-manager/fm-search-list-view.c: (real_adding_file):
	Fixed formatting mistake.

	* src/nautilus-view-frame.c: (set_up_for_new_location): Emit
	the title_changed signal for each change in location.
