With the removal of i4X4 and SPLIT_MV modes, the two entries for the
modes are no longer used. This patch remove the coding of the deltas.

Changes to the coding of transform sizes, along with forward
and backward probability updates.
Results:
derf300: +0.241%
Context based coding of transform sizes will be in a separate
patch.

Wrong max data size (skip has no data) and use of vp9_get_segdata()
when it should be vp9_segfeature_active().

ref_frame in MB_Mode_Info was changed in the ref frame coding patch
to be an array to handle first and second reference frame, this patch
fix the loop filter code that use the pointer directly as reference
frame.

Code intra/inter, then comp/single, then the ref frame selection.
Use contextualization for all steps. Don't code two past frames
in comp pred mode.

Split partition probabilities between keyframes and non-keyframes,
since they are fairly different. Also have per-blocksize interframe
y intramode probabilities, since these vary heavily between different
blocksizes.
Lastly, replace default probabilities for partitioning and intra modes
with new ones generated from current codec. Replace counts with actual
probabilities also.

This version of the loop filter supports non-4:2:0 subsampling and
a fourth plane, as well as changing the filtering order to be more
friendly to hardware implementations.
The filters are applied first to all vertical edges within the
64x64 SB, followed by the top horizontal edge and any internal
horizontal edges. Since filtering is applied on each 4x4 edge
serially, a dependency is created from filtering one block edge
to the next. It would be possible to remove this depencnecy by
building all filtering decisions from the unfiltered
reconstruction data.

This avoids encoding tokens for blocks that are entirely
in the UMV border. This changes the bitstream.

This commit makes the coding/reconstruction operations of intra
coding rate-distortion loop for UV components consistent with those
of the encoding process.
key frame coding gains:
derf: 0.11%
stdhd: 0.42%

Adds backward adaptation and differential forward updates of switchable
interpolation filter probabilities. Also adds some cosmetic cleanups
and minor fixes on mv_ref probabilities.
derfraw300: +0.353% (with most coming from switchable interp changes)

Restrict get_matching_candidate() to considering
mvs at 8x8 and larger sizes for last frame case.
This is to reduce the HW load of using vectors down
to the 4x4 level from the previous frame.

This speed 1 - uses variance threshold stolen from static-thresh
to determine split. Any superblock with greater than the variance
set by static thresh * quantizer index squared is split. In addition
transform size is set to largest size less than or equal to partition
size, sub pixel filter is set to normal, and only 12 modes are used
at all.
