Fixed point reference picture scaling
Fixed point scaling factors are calculated once for each
reference frame by using integer division. Otherwise fixed point
scaling routines are used in all scaling calculations. This makes it
possible to calculate fixed point scaling factors on device driver
software and pass them to hardware and thus avoid division on hardware.
TODO:
- Missing check for maximum frame dimensions
(currently scaling uses 14 bits)
- Missing check for maximum scaling ratio

It seems like I inverted the meaning of the contexts by accident?

TX_SIZE contexts simplification.
Reduces TX_SIZE contexts to 2 for each kind. The code is
cleaner and there is hardly any performance difference with
more than two contexts.
Results: almost neutral

Uncompressed header: new encoding for frame size
For key frames everything is the same as before. For inter frames we try
to reference last/golden/altref frame size. If there is no match then the
actual size is encoded. Also we don't allow zero width and height anymore.
