* 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 reverts commit 401204a5.

Change-Id: Id27eadf679b0df2d2ccfab61155be29979b0b6ba

This prepares the integration of rectangular transform block size
with recursive transform block partition system.

Remove redundant experimental flag. This does not change the coding
statistics.

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).

Count the transform block partition context in the unit of pixels.

Reverted commit: f8306bfd (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.

1. Avoid compiler warnings.
2. Enable prob_diff_update() required by update_txfm_probs().
