Since the scaled luma can be negative, ROUND_POWER_OF_TWO_SIGNED must be used.
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
passed inc_mv_cdf() instead of its pointer type.

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.

Fix a rare case in which the tile boundary information was not
set up properly in the decoder when using LOOPFILTERING_ACROSS_TILES

The situation was:
* One frame uses loop filtering across tiles. Then its tile
  boundary information is not needed, so is not calculated.
* The next frame (in decode order) has the same size and the
  same tile layout, but doesn't use loop filtering across tiles.
* Now the tile boundary information *is* needed, but we weren't
  recalculating it. This resulted in the loop filter being
  applied across tile boundaries even though we signalled not to.

Since the conditions on when we can reuse the previous frame's
boundary information are complex, and the overhead of calculating
the tile boundaries is low, we avoid this issue by simply
recalculating the boundary information each frame.
