First part of file chooser fixes.
* gtk/gtkfilechooserbutton.c (model_add_special): also set the
handle in the model for the desktopdir case.
* gtk/gtkfilechooserdefault.c (shortcuts_add_current_folder): free
volume in case we retrieved it but don't pass it on to insert_path,
(shortcuts_model_create): change the column type for the handles
to pointer instead of GObject so our handle ref counting is not
disturbed,
(show_and_select_paths_finished_loading): don't forget to unref
the dialog.
* gtk/gtkfilesystemunix.c (gtk_file_system_unix_class_init),
(gtk_file_system_unix_init), (gtk_file_system_unix_dispose):
remove pending execute_callbacks_idle during dispose, also
execute all callbacks waiting to be run in the next idle,
(queue_*callback), (execute_callbacks_idle): refactor to maintain
a list of callbacks to call per file system instead of globally,
guard the file system during callback invocation,
(gtk_file_system_unix_get_folder): only add load folder idle if
none has been added yet.
