vpxdec stays in a loop when decoding vp9.  This patch is a
quick fix to stop the loop when all data has been decoded.
Eventually we should move the vp9_get_raw_frame() call into
vp8_get_frame().

Removes the case of coding prob = 0 for forward updates, since that
is not an allowed probability to code.
Slightly improves efficiency but may not matter in practice.

This commit enables proper partition type search for the bottom-
right corner blocks.

Change-Id: Id1123d0e4e81eba648ed4f3c0c7ab587e174f650

This commit fixed the allowable partition types for bottom-right
corner blocks.

When a block has over half of its pixels as valid content in both
vertical and horizontal directions, allow all the four partition
types in the bit-stream. Otherwise, apply partition type constraints.

* Makes a change to not reset to defaults for the tx_size
probs if an intermediate frame reverts to using a fixed tx_size.

Removes unused filters and the code for the case of 2 switchable filters;
also changes the 8tap-smooth filter coefficients for integer shifts to be
interpolating to be consistent with the way it is implemented currently.

Change-Id: I07dc1b0682845bc18fe0efa6af5e4f4da3abfa3a

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
   (upscaling 16:1, downscaling 2:1)

Problems:
 - Straightforward fixed point implementation can cause error +-1
   compared to integer division (i.e. in x_step_q4). Should only
   be an issue for frames larger than 16k.
