ovl: generalize the lower_layers[] array
Rename lower_layers[] array to layers[], extend its size by one and
initialize layers[0] with upper layer values. Lower layers are now
addressed with index 1..numlower. layers[0] is reserved even with lower
only overlay.
[SzM: replace ofs->numlower with ofs->numlayer, the latter's value is
incremented by one]
