Modified to work with 8x8 blocks of memory.  Will revisit
later for further optimizations.  For the HD clip used, the
decoder improved by almost 20%.

Encoding time of crew (CIF, first 50 frames) @ 1500kbps goes from 4min56
to 4min42.

* changes:
  Remove unused vp9_idct_add_{y,uv}_block
  Remove some unused loopfilter code

These functions are not used, and appear to have been superceded.

This code is unreachable, and not useful for later reference.

The mmx routines work as expected for the loop filter, so enable them.

Change-Id: I2bbd9b99a4445fcba17bb95002f1fb6e01fe8f85

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().

The encode-side scaling was not indexing through the image correctly
for the chroma planes, causing a green checkerboard-like output in
the unit test.

A corrupt bitstream could refer to a reference frame that has no size.

Previous code indexed using the tile length coded in the bitstream
without checking that the read would be valid.

Change-Id: Ia5047762223a4f80d75016dd546dc2ef18b6887d

Fixes a condition where the address of the mismatching pixels was not
being found/printed.

Change-Id: Ifac5cd3471bc2437448128591eea7c7b87e2d8fe

Don't do the 15 tap filter if there aren't 8 pixels below/right of the
edge.

Change-Id: I62f16437c1d9ba59b6901a5fe71ddb2f472da344

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.

Avoids divide-by-zero when variance is 0.

* New probs for subpel filters/tx_count
* Makes a change to not reset to defaults for the tx_size
probs if an intermediate frame reverts to using a fixed tx_size.
* A few updates to the parameters for backward adaptation for mode/mv
* some cosmetic cleanups

This is consistent with uncompressed header encoding.

Remove the bilinear filter mode, and the no-loopfilter mode, and the
related vp9_setup_version() function.
