This commit resolves the broken coding pipeline in ext-tile when
obu is enabled. It fixes the unit test failure due to enc/dec
mismatch.

When lv-map and new-quant are enabled together,
av1_read_coeffs_txb currently does not use the new-quant
lookup table to get the dequantized value, which causes an
encode/decode mismatch. This patch fixes the function to
make lv-map work with new-quant.

The inverse transform API was changed to pass in an unpadded 32x32
block of coefficients for transforms larger than 32x32, but the
code path actually used for daala_tx was not modified to pad it out
to the full size like the others were.

Added is_compound in ConvolveParams, so that later we could handle
single ref and compound ref differently in optimization.

For ext-skip, if a partition block uses the new skip mode,
NEAREST_NEARESTMV is the prediction mode. Other predictions were once
tried out but did not show noticeable coding gains.

This patch modified convolve function prototype. The temp buffer used in
convolve function is already available in conv_params, which doesn't need
to be passed in. Instead, pass in the destination buffer so that the
result can be written in the destination directly for single ref case.
More patch will be followed.

This adds part of the proposal in "AV1 Tile Overview v1_1".
A new dependent_horztilegroups configure option is added
(disabled by default).

The experiment adds syntax dependencies between tile groups.

"+ 1" has been added in a few locations to match the indices for the
context for the CDFs and the motion vectors.

Suggested fix (of removing +1s entirely) can then be implemented
without further affecting the overall behaviour of the encoder and
decoder.

This enables CDEF for chroma when the horizontal and vertical
subsampling differs.  Since the direction search is only performed in
luma, the following corrections to the direction index are done for
chroma to correct the distortion resulting from the subsampling:

4:2:2:   4:4:0:
0 -> 7   0 -> 1
1 -> 0   1 -> 2
2 -> 2   2 -> 2
3 -> 4   3 -> 2
4 -> 5   4 -> 3
5 -> 6   5 -> 4
6 -> 6   6 -> 6
7 -> 6   7 -> 0

This improves the chroma PSNR BDR by about 2% for 4:2:2 content at
cpu-used=4, low delay configuration.  4:2:0 and 4:4:4 content is
unchanged.

For ext-skip, the use of distance-weighted prediction has only shown
a coding gain in the AMCY low delay scenario. It is hence not being
considered and compound-average is used exlusively.

based on the latest discussion in the HW working group about how loop
filter should be integrated with tiles, the following decisions have been
made:
1. two seperated flages should be added for
loop_filter_across_tiles_enabled for horizontal tile boundary and
vertical tile boundary.
2. encoder and decoder should only check these two flags to determine
whether loop filtering (including deblocking, CDEF and loop restoration)
should cross tile boundaries (vertical and/or horizontal) or not
regardless the horitontal depepdent tile flag.

This change list implemented the support for two seperated
loop_filter_across_tiles_enabled flags for vertical and horizontal tile
boundaries. The new experiment is disabled as default before it is
adopted.

When the optimized non-zero tail is longer that 2, the likelihood
that forcing to drop all the tail coefficients would give better
rate-distortion optimization is much lower. This commit makes the
encoder to check such conditions and speed up the lv-map/multi
encoding speed.

Local test clips at high target bit-rate / quality show 20% overall
encoding speed up. The coding performance change for lowres is
0.014%.

This makes motion by function easier in some editors (such as Emacs or
vi), which get a bit confused by

  #if 1
  foo {

This makes code motion a bit easier in editors. To do so, remove some
copy-paste code in scale_references and rewrite a duplicated loop in
set_high_precision_mv.

This patch should have no effect on behaviour.

By default, the DC_PRED is not cached (this includes
decoding). During cfl_rd_pick_alpha(), DC_PRED caching
is enabled, the DC_PRED is cached after the first time it
is computed (for each plane) and then it is reused when
testing all the other scaling parameters.

To avoid using a UV_PREDICTION_MODE with intra_mode_to_tx_type_context,
a wrapper function is added. Using a UV_PREDICTION_MODE with
intra_mode_to_tx_type_context is problematic with UV_CFL_PRED which
needs to be converted to DC_PRED.
