When this was an array of layer_mask_t, the name layer_masks was a
description of that underlying data type.  Now that we have removed
the layer_mask_t datatype, it is not as obviously true any more.

When trying to name these variables after the "role" that they have in
their declaration context, I think of them as "unfulfilled per-layer
access requests", but that strikes me as a bit long.

For the upcoming patch set, I'm leaning towards naming these variables
just "masks", to keep it short.

I'm afraid that this one did not get any further than what it already
was, and I'll have to leave it out for now.  But I have it on my TODO
list.
