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.

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.

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.

and will allow reuse in the decoder.

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

Change-Id: I5a51c4065a1493e2e2a544d243907672614752a7

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).

This patch fixes a regression introduced in 1d190950 where the encoder
 was using the 4x4 VP9/AV1 transforms for RDO, but then used the Daala
 transforms for encoding.
The ~2% improvement below comes from forcing the C implementation of the
 4x4 and 8x8 transforms to be used when CONFIG_DAALA_DCT4 and
 CONFIG_DAALA_DCT8 are enabled respectively.
