- If invisible pixels, av1_daala_dist() simply use source pixles for dst.
- Added av1_daala_dist_diff() which inputs diff signal instead of dst.

- Refactored daala_dist code so that av1_daala_dist() and _diff()
is called inside av1's distortion calculation functions, pixel_sse() and
sum_squares_visible().

This patch changes the motion vector scaling and clamping to be
slightly more accurate (removing an occasional 1px offset due to
multiple roundings) and fixes the border clamping when scaling
frames.

This reverts commit a3d70911.

Reason for revert: this was fixed in cb637674 which moved the
definition to a different line causing this change to merge
cleanly, resulting in a duplicate.

NCOBMC_ADAPT_WEIGHT allow using different interpolation kernels
to combine overlapped predictions generated using mvs in the
neighboring blocks.
This experiment will build on top of MOTION_VAR and it might conflict
with WARPED_MOTION in the developing stage, so will only be effective
when MOTION_VAR is on and WARPED_MOTION is off.

The special path in build_inter_predictors for chroma blocks
corresponding to sub8x8 luma blocks would always fetch the
scale factors from 'xd', which correspond (at least in the
decoder) to the references of the block for which is_chroma_reference
returns true.

The correct behaviour is to fetch the scale factors from 'ref_buf',
which corresponds to the references of the block currently being
predicted.

This patch fixes some encode/decode mismatches which were caused
by the above behaviour when the various reference frames had
different sizes.

Previously, for block >=8x8, and tx < 8x8,
we skipped setting the early-exit flag in block_rd_txfm() because
distortion for sub8x8 tx block is from MSE but reference (best)
is from daala-dist.
However, not setting early-exit flag turned out to be the reason
for a regression in MSE probe mode of daala-dist because
it loses the chance to set rd_stats properly.

On the other hand, there is still a small regression, say 0.05% psnr bd-rate,
which seems to occur in the case that a tx block in a partition has chosen
the skipped rd_cost since it is smaller than non-skip rd_cost and
set the early-exit flag to 0 (so, not exit), but the daala-dist applied
to the whole partition cannot access the same info but can choose from
two kinds of rd_costs:
1) all tx blocks are skipped (even if a tx block has non-zero coeff) and 0 bits
2) sum of final distortion of all tx blocks (i.e. non-zero coeff decoded)
and bits to encode coeffs.

cb4x4 itself should not require these sizes.

This simplifies compatibility with other experiments, since we can
first make them work with cb4x4 (which is now on by default), and
then worry about chroma_sub8x8 and chroma_2x2 (which is not) in
separate steps.

Encoder and decoder output should remain unchanged.

When writing the compressed header, prob_diff_update() was called
for compound_type_prob[] for every defined block size, even though
luma never uses block sizes smaller than 4x4.

This fixes is_any_masked_compound_used() and
is_interinter_compound_used() to properly return 0 for chroma-only
block sizes, and then uses these functions to guard the probability
updates in write_compressed_header() and read_compressed_header(),
the same way the actual compound type values are guarded in
read_inter_block_mode_info() and pack_inter_mode_mvs().

Without tempmv-signaling configured, using the previous frame's MVs
requires that the last frame was a show frame. With tempmv-signaling
configured, cm->show_last_frame is not checked when calculating
use_prev_frame_mvs. This patch adds that check and resolves mismatches
seen with random resizing and random superres.

Includes a couple fixes too - cm's last_width, last_height, and
last_show_frame were updated under different conditions. Now they're all
updated at the same time.
