* 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
Pass 1/2 frame 50/51 8976B 1436b/f 86169b/s 2902620 us
(17.23 fps)
Pass 2/2 frame 25/0 0B 2933053 us 8.52 fps [ETA unknown]
aomenc: ../../av1/encoder/cost.c:46: cost: Assertion `prob != 0' failed.

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.

Start adding cmake build support. This is based on the generic-gnu
target and will not build anything. It simply produces a project file
(when generating for a IDE) that can be loaded and that allows for
interaction with (most of) the aom sources used in a generic-gnu
build.
Notable missing pieces:
- flag testing
- config generation
- experiment configuration
- enable/disable encoder/decoder
- aomenc/aomdec
- all third party library build integration
- all tests
