OK, staring at the code a bit longer, I realize that since the type is
now named "struct layer_access_masks", "layer_masks" is actually still
a reasonable shorthand.  I have abbreviated that to "masks" in some
places where it is anyway clear from the context that those are the
layer access masks, but left it as "layer_masks" in places where we
also use other access masks, for disambiguation.
