Now the single ref comp mode should work with WEDGE and
COMPOUND_SEGMENT. For motion_var, the OBMC_CAUSAL mode uses the 2nd
predictor if the neighboring block is single ref comp mode predicted.

This patch removes the mode of SR_NEAREST_NEWMV and leaves four
single ref comp modes in total:

SR_NEAREST_NEARMV
SR_NEAR_NEWMV
SR_ZERO_NEWMV
SR_NEW_NEWMV

A new experiment SBL_SYMBOL, meaning superblock-level symbols, will
be explored. It allows some symbols being coded at superblock level
(64x64) by checking whether a symbol(e.g. motion_mode, tx depth,
and interpolation filter) is identical across macroblocks in a
superblock.

This reverts commit bf3813a1.

Reason for revert: feature not ready.
Incompatible with lossless under some circumstances,
causes the following assertion failure:
Assertion `(!is_compound) == (cm->reference_mode == SINGLE_REFERENCE)' failed

Earlier, intra prediction for rectangular blocks was performed by
running two steps of prediction on square sub-blocks.

With this experiment, we do proper intra prediction for rectangular
blocks. This ensures that we make use of all available neighboring
pixels especially for directional modes. For this, all the intra
predictors were updated to work with rectangular transform block sizes.

Performance improvements are small but free of cost:

All Intra frames:
lowres: -0.126
midres: -0.154

Video Overall:
lowres: -0.043
midres: -0.100

[Could not get AWCY results due to a backlog.]

Move the large stack allocation from stack initialization to
dedicated mem space. This resolves the extremely large stack issue
when ext-partition, motion-var, and high bit-depth are all turned
on.

This coding tool is targeted to check redundant references available
to each frame at the frame level, and then try to save bits to avoid
coding redundant reference information at the block level.

This was being worked around by forcing highbitdepth to be off when
enabling tx64x64.

With the fixes, removed the work-around.

Encode a block line by line, horizontally or vertically. In the vertical
mode, each row is predicted by the reconsturcted row above;
in the horizontal mode, each column is predicted by the reconstructed
column to the left.

The DPCM modes are enabled automatically for blocks with horizontal or
vertical prediction mode, and 1D transform types (ext-tx).

We no longer support armv6 and the corresponding
optimized source files have been removed. This
commit removes support for the target and its
media instruction set extensions from the build
system as well.

Once armv6 jobs are removed from the integration
config we can start rejecting --enable/disable-media.

Also reject --enable-edsp.

This causes the HBD operating path to be compiled by default, allowing
default builds to handle all AV1 profiles, instead of only Profile 0.
This doesn't change the current behaviour of the code.

This will help ensuring the HBD operating path continues to compile.

this change enables loopfiltering_across_tiles by defualt after
it has been adopted. support in the deblocking filter and CDEF
filter has been implemented. a command line argument --tile-loopfilter
has beed added to enable (1) or disable (0) loop filter across
tile boundarys.
