Before this patch we were passing in the number of pixels as
number of 4x4 blocks, thus allocating much more memory than
necessary. With this patch, the heap usage on a CIF test clip
drops from 130MB to 93MB.

When Chroma from Luma is combined with chroma_sub8x8, the prediction
used for sub8x8 blocks originates from multiple luma blocks. Extra
asserts are added to validate that the prediction buffer contains all
the required information.

This patch eliminates the is_inside() checking for each neighouring
block in scan_row_mbmi() and scan_col_mbmi(). Instead, in
setup_ref_mv_list(), find maximum above row_offset and left col_offset
for current block, and use them to decide which above rows and left
columns to search on. This patch doesn't change bitstream. No
noticeable speedup is seen.

This changes the behavior from rounding toward -infinity to rounding towards 0.

Patch 5c06a646 pulled the "if (!cm->loopfilter_across_tiles_enabled)"
check out of av1_setup_across_tile_boundary_info, intending for the
condition to be checked in the caller instead. The check was added
to the decoder but not to the encoder, leading to encode/decode
mismatches when the flag was set.

Fix this by correctly applying the change to the encoder as well.

With recent changes, it is now possible to store the storage
flag inside the CFL_CTX. This simplifies the implementation
and will allow reuse in the decoder.

This change does not alter the bitstream.

Change-Id: If781aac66b47c1a707f4f9a647cb8a3294477a48

Reworked how the storage flag is set to avoid duplication on the encoder
side. Reconstructed Luma pixels are stored in encode_superblock in the
loop that calls av1_encode_intra_block_plane and in the extra call to
txfm_rd_in_plane after the luma RDO, but prior to the chroma RDO.

This change does not alter the bitsteam.

When CONFIG_EXT_INTER is disbaled, an instane of struct nmv_context is

When updating default_partition_cdf, this sums the probabilities that
were divided evenly across the pairs PARTITION_HORZ_A/PARTITION_HORZ_B
and PARTITION_VERT_A/PARTITION_VERT_B. Those summed probabilities now
get distributed evenly across the triples you get by adding
PARTITION_HORZ_4 and PARTITION_VERT_4, respectively.

Rather than implement 2X8/8X2 blocks for now, ss_size_lookup returns
4X8/8X4 block sizes to use as chroma transform sizes for 4X16/16X4
blocks.

The changes in setup_pred_plane and set_skip_context are because this
is presumably the first time we've had to deal with 16x4 or 4x16
blocks. Since BLOCK_16X4 is not less than BLOCK_8X8, the existing
logic didn't work (and the "shuffle back one" logic should probably be
done for small widths and heights separately).
