Guess zpos from plane type
...
Many drivers don't expose the zpos plane property. We can guess it from the
plane type though: primary, overlay, cursor. Except some drivers expose
underlays too: underlays, primary, overlay, cursor. Underlay planes don't have a
special type, they are just marked as overlays. To detect them, check whether
their plane ID is less than the primary plane ID.

Reset best allocation to NULL

Without this, if no allocation has been found, garbage will be read from

Change planes to be a linked list instead of an array
...
We'll need this anyway when we allow users to choose which planes to give us.
Let's not start building algorithms on top of arrays.
