Disallow to rename the layer mask. Instead, always name the mask
"<layer name> mask". Fixes bug #133112 along with some other
unreported ones.
* app/core/gimpitem.[ch]: added a boolean return value indicating
success to GimpItem::rename().
(gimp_item_real_rename): push an undo step only if the item is
attached.
* app/core/gimplayer.c (gimp_layer_rename): refuse renaming if
the layer is a floating selection floated from a channel
(renaming a layer's floating selection makes a new layer out
of the floating selection).
(gimp_layer_duplicate): use gimp_layer_add_mask() to attach the
mask's duplicate. Fixes mask refcount brokenness for duplicated
layer masks.
(gimp_layer_name_changed): new function. Automatically renames the
layer mask when the layer's name changes.
* app/core/gimplayermask.c (gimp_layer_mask_rename): new function
which refuses renaming.
(gimp_layer_mask_name_changed): skip the unique name voodoo
GimpItem does by not chaining up.
(gimp_layer_mask_set_layer): change the mask's name whenever it is
attached to a layer.
* app/text/gimptextlayer.c (gimp_text_layer_rename): fiddle with
text_layer->auto_rename only if renaming was successful.
* app/widgets/gimpitemtreeview.c (gimp_item_tree_view_name_edited):
restore the old name if renaming failed.
* tools/pdbgen/pdb/drawable.pdb (set_name): return an execution
error if renaming failed.
* app/pdb/drawable_cmds.c: regenerated.
