Simplify prepare and set semantics (comments only)
Documentation updated for semantic changes vs. HWC 0.x:
* Prepare won't be called with NULL pointers. This used to be used to
disable hardware composition, though that wasn't documented. Now
we'll call prepare with non-NULL pointers but the layer list will
have zero layers.
* Set won't be called with NULL pointers. This used to cause the
display to turn off; that is now done by calling the blank() method,
which is no longer optional.
