The function module in inter_predictor() has been changed to
universally support arbitrary block size inter prediction. Hence
sub8x8mc can be a standalone experiment now.

The rectangular transform syntax is by default supported, hence
no need to put it under the experimental flag. This does not change
the coding statistics.

* changes:
Avoid the "initial copy" in the deringing filter
Only copy the deringed blocks back into the buffer
Reducing copies in deringing filter
sb_all_skip_out() now computes a list of deringed blocks
compute bskip as we go
Revert "Fix dering filter when using 4:2:2 or 4:4:0 subsampling"
This prepares the integration of rectangular transform block size
with recursive transform block partition system.

Upsampled references currently increase the size of references by
64 times. This patch limits the memory used by the encoder to
about 3GB when encoding high bit depth content.
This should be re-evaluated in the future, if doing 8-tap
resampling in the motion search becomes reasonably fast, or if
the upsampled references are reduced in size (by omitting some
subpel positions and interpolating them instead).

Reverted commit: f8306bfdc (with some changes).
Reason: This was triggering an assert in debug build because of zero
probability values. So, using an "UNUSED_PROB" macro to replace these to
retain clarity.
Assertion failure can be reproduced as follows:
$ make clean; extra_cflags='-O0 -g -fno-inline' ../../configure
--enable-debug --enable-experimental --enable-palette && make -j 16
$ ./aomenc -D --codec=av1 ~/videos/screen_content_set/gimp.y4m -o
/tmp/foo.webm --tune-content=screen --limit=50

This commit allows the partition context model to account for the
maximum transform block size of the coding block.

- Add unit tests to verify the bit-exact result.
- User level time reduction (EXT_TX):
encoder: 3.63%
decoder: 2.36%
- Also add tx_type=V_DCT...H_FLIPADST SSE2 for 16x16 inv txfm.
