* Remove some unused variables
* Reduce need for casts by typing intermediate buffers appropriately
* Avoid copying data which is never modified; use the original data
  instead.
* Reduce number of intermediate buffers required, saving allocations
  of 576KiB in the decoder and ~1MiB in the encoder

This commit enables the cb4x4 mode to support ext-tx experiment. The
coding performance gains are:

       ext-tx   cb4x4    ext-tx + cb4x4

midres  2.1%     1.2%      3.0%

Similarly to the refactoring of PVQ codes for 4x4 intra,
instead of calling tx and pvq_encode_helper() in 4x4 inter,
av1_xform_quant() is called.

This commit gives no change in metrics.

This commit adds a new experiment to allow disabling of loop filtering
on tile boundaries. It is implemented by adding a syntax field
"loopfilter_across_tiles_enabled" into the uncompressed frame header. 
If it is set to 0, decoder and encoder will disables loop filtering for
block edges that are also tile boundaries.

In 4x4 intra search for RDO, AV1 codes has been changed to
call av1_xform_quant() while ago, while PVQ did not but call
txfm and pvq_encode_helper() instead, which caused duplicated codes
and thus worse maintenance and testing.

This refactor also has fixed the long-sitting bug,
which we couldn't find before refactoring.

The convolve filters generated by loop_wiener_filter_tile
are not compatible with some existing convolve implementations
(they can have coefficients >128, sums of (certain subsets of)
coefficients >128, etc.)

So we implement a new variant, which takes a filter with 128
subtracted from its central element and which adds an extra copy
of the source just before clipping to a pixel (reinstating the
128 we subtracted). This should be easy to adapt from the existing
convolve functions, and this patch includes SSE2 highbd and
SSSE3 lowbd implementations.

This commit allows the sub8x8 blocks to compose and filter their
chroma components for supertx in cb4x4 mode. The coding gains of
supertx and cb4x4 are largely additive:

          supertx      cb4x4       cb4x4 + supertx
lowres     -1.0%       -2.7%        -3.64%
midres     -0.8%       -1.3%        -2.10%
