Rename MI_BLOCK_SIZE.* -> MAX_MIB_SIZE.* (MIB is for MI Block).
Rename MI_MASK.* -> MAX_MIB_MASK.*
There are no functional changes.
This is in preparation for coding the superblock size at the frame
level, which will require some of these constants to become variables.
The new names better reflect future semantics, and hence make the code
clearer.

If --enable-ext-partition is used at build time, the superblock size
(sometimes also referred to as coding unit (CU) size) is extended to
128x128 pixels.

This has been ported under ext_partition_types because it is due
to be combined with the coding_unit_size experiment which is
already being ported under ext_partition

Combinations of different mv modes for two reference frames
are allowed in compound inter modes. 9 options are enabled,
including NEAREST_NEARESTMV, NEAREST_NEARMV, NEAR_NEARESTMV,
NEAREST_NEWMV, NEW_NEARESTMV, NEAR_NEWMV, NEW_NEARMV, ZERO_ZEROMV,
and NEW_NEWMV.
This experiment is mostly deported from the nextgen branch.
It is made compatible with other experiments
Coding gain of EXT_INTER(derflr/hevcmr/hevchd): 0.533%/0.728%/0.639%

Current implementation is a bilateral filter whose
parameters are transmitted in the bitstream.
derflr: -0.647% BDRATE
hevcmr: -0.794% BDRATE
This is a prelimary patch. Various other variations are to
be investigated next, that will hopefully be less expensive
on the decoder side.

NEW2MV is enabled, representing a new motion vector predicted from
NEARMV. It is mostly ported from nextgen, where it was named
NEW_INTER.
A few fixes are done for sub8x8 RDO to correct some misused
mv references in the original patch.
A 'bug-fix' for encoding complexity is done, reducing the additional
encoding time from 50% to 20%. In sub8x8 case, the old patch
did motion search for every interpolation filter (vp9 only
searches once). This fix also slightly improves the coding gain.
This experiment has been made compatible with REF_MV and EXT_REFS.
Coding gain (derflr/hevcmr/hevchd): 0.267%/0.542%/0.257%
Change-Id: I9a94c5f292e7454492a877f65072e8aedba087d4
Various additional changes were made to make the experiment
compatible with misc_fixes.
derflr: +0.979%
hevcmr: +0.865%
Speed-wise with --enable-supertx the encoder is only about 10%
slower than without. Decoding impact is about 30% slowdown.
Note this does not work with ext-tx or var-tx yet. That is
a TODO.
Change-Id: If25af4241a7a9efbd28f58eda3c4f044c7a7ef4b
Remove MISC_FIXES flags except for the changes on MV precision, which
has a 0.1% performance drop.
On derflr, the impact is -0.012%.

This commit allows the loop filter to account for the recursive
transform block partition when selecting the filter and mask.
Change-Id: I62b6c2dcc0497cbe1f264b03c46163f55d2c9752
This commit refactors the loop filter selection process to support
variable transform block sizes based filter mask. It disables the
multi-thread loop filter implementation to simplify the experiments.
The speed impact on speed 0 encoding is negligible.

In practice, this fixes the issue that if you have an odd number of
mi_cols, on the full right of the image, the UV int4x4 loopfilter
will be skipped over odd cols as well as odd rows (because it holds a
single variable for both edges).
See issue 1016.

The implicitly changed value would be used for contextualizing future
skip flags of neighbour blocks (bottom/right), which is certainly not
what was intended. The original code stems from vp8, and was useful
in cases where coding of the skip flag was disabled. In vp9, the skip
flag is always coded. The result of this change is that for bitstream
parsing purposes, decoding of the skip flag becomes independent of
decoding of block coefficients.
See issue 1014.
