Remove the restriction that the neighboring predictor cannot be
used in obmc prediction if it is an interintra or wedgeinterinter
block. The inter predictor of the interintra block, or the first
inter predictor(using LAST or GOLDEN frame) of the wedgeinterinter
block will be exploited in obmc prediction.

The bug is introduced by commit 1a0352d, in which mv costs are
counted twice in joint_motion_search() in ext_inter experiment.

This commit enables 1/8 luma component motion vector precision
for all motion vector cases. It improves the compression performance
of lowres by 0.13% and hdres by 0.49%.

Reduce transform set for intra for 8x8 and smalller to 7 from 12.
Also fixes an issue with prob updates.
Enocder Speed-up about 8-10%
Coding efficiency very little change.

Block size passed into denoiser filter is always >= BLOCK_8X8 (in
vp9_pick_inter_mode), it is not necessary to check smaller block
size. Passed the bitexact test on clips with different resolutions and
noise levels.

Fix will reset the consec_zero_mv map on non-skipped blocks with non-zero mv.
Adjust thresholds on consec_zero_mv in noise estimation and skin detection,
as more possible reset on map means lower thresholds should be used.

webm_read_frame is the only function now which requires
documentation for what the return value means (other two are quite
obvious - file_is_webm and webm_guess_framerate).

In VP9 internal denoiser, motion magnitude is computed from
best_sse_mv, which should be set to 0 at the begining. This bug may
cause visual aritifact in denoiser. Also, delete two improper comments.

MMX and X87 floating point instructions cannot be mixed freely on
the 32 bit x86 architecture.
This fixes a lot of unit tests in the 32bit build with
--enable-ext-intra.

Need to check that sse for non-zero mv has been set for the current block
(i.e., check that nonzero-mv is tested as a mode, so newmv_sse != UINT_MAX)
before forcing to not use zero-mv for denoising.
Also increase some thresholds (sse and sse_diff) for high noise case,
and use shift operaton instead of multiplication on a threshold computation.

- Optimization on tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Overall encoder speed improves ~4.5%-6%.
- Update bit-exact unit test against current C version.

Resolved two TODO items.
Force a minimum value of 1.0 for frame duration as per section duration.
Column inactive zone is currently set to 0 as most of the serious issues
relating to inactive regions relate to letter boxing.

In Aq mode 1 the segment and AQ delta for each block is based
on spatial variance. There may be a net imbalance between blocks
that have lower Q than the baseline value and those that have higher Q.
This patch monitors that imbalance and extends the allowed baseline
Q range for the frame to accommodate adjustment of that baseline value
to compensate.

This commit fixes an out-of-bound memory access case in the
loop filter mask setting. This issue was introduced in
