Do the same for tools.

BUG=aomedia:828

Change-Id: I284dd44ae57c461012ae2b034a23a3cad9361af0

This is the first tool in the CMake build, so some extra
noise is involved:

- Setup tools list vars and handling.
- Add tools support to the dist rule.
- Move usage_exit.c generation to CMakelists.txt to allow
  use by the aom_entropy_optimizer target.

This hides behind --enable-ext_partition_types_ab. When that flag is
set, the mixed partitions change from

   +-+-+---+          +-+-+---+
   |   |   |          | | |   |
   |---+   |    to    | | |   |
   |   |   |          | | |   |
   +-+-+---+          +-+-+---+

(that's PARTITION_VERT_A; other partitions change similarly).

Since 128x32 and 32x128 block support hasn't yet been merged, this
patch also temporarily disables these partitions for 128x128 blocks.

The updates in this CL are for the scenario when ext-comp-refs is off.

For --disable-global-motion --disable-ext-tx --disable-ext-comp-refs
--disable-convolve-round, the patch obtains a small BDRate gain for
PSNR: lowres -0.08%; midres -0.05%

Move functions related to frame index in natural order setup into
a root experiment.

Change-Id: Iebc71514b951dbb658cf0e1c3d42bb2b180d830f

The frame index in natural display order is needed by several
experiments, hence move it as a root experiment. The additional
overhead cost associated with frame_marker is below 0.05% level.

This should relief the concern of latency incurred by generating
scan order

CfL now consistently uses clip_pixel. This change does not alter the
bitsteam.

Coefficient prob model was removed earlier in
https://aomedia-review.googlesource.com/c/aom/+/17062, so these were
unused and updating them was a wasted effort.

This table was removed in this patch:
https://aomedia-review.googlesource.com/c/aom/+/17062/12/av1/common/entropy.c#b1411,
so no need to optimize it anymore.

For prediction block width equal to 32, avx2 can further speedup
the prediction function (i7-6700):

32x32     avx2 v. sse2
DC        ~1.4x
top       ~1.5x
left      ~1.4x
128       ~1.5x
v         ~1.6x
h         ~1.2x

32x16     avx2 v. sse2
DC        ~2.2x
top       ~1.7x
left      ~1.6x
128       ~1.8x
v         ~1.9x

Note: 32x16 H_PRED on avx2 does not run faster enough than sse2 yet.

Also, do not increment the offset for cases that don't use quantization
matrices.

This prevents the offset from going beyond the array size.

2. Run "make test" to download lightfield test data: vase10x10.yuv.
3. Run lightfield encoder to encode whole lightfield:
  examples/lightfield_encoder 1024 1024 vase10x10.yuv vase10x10.webm 10 10 5
4. Run lightfield decoder to decode a single tile:

Note: Enabled use of AOME_USE_REFERENCE(previously deprecated) for this
example.

Experiment LOOPFILTER_LVL has 4 deblocking filter levels for:
y plane horizontal, y plane vertical, u plane, and v plane.

The patch supports segment updates for each of the four filter levels.

Change-Id: I494e8d9ab67e37c5f6234b8d9db8e3e3abf70d52

With ext-partition and tx64x64 enabled, the encoder could choose
TX_64X64 to encode the transform for a subsampled plane of a
BLOCK_128X128 block. This broke an assumption in the nested loop in
write_tokens_b and also caused bug 827 (with a rather cryptic
failure).

This patch changes get_vartx_max_txsize to ensure that the encoder and
decoder don't think they can use TX_64X64 in this situation. It also
adds a couple of assertions to the loop mentioned above so that if
something comes unstuck it'll be much more obvious what went wrong.

1. seg->temporal_update flag is only read when seg->update_map flag is
set to 1 in the bit stream. in case update_map flag is different from frame
to frame, the temporal_update flag will not be reset to 0 when
update_map flag changed from 1 to 0. i.e, the previous temporal_update
flag will be used in the later process. in the read_inter_segment_id
function, temporal_update flag is used to read the segment id. it will
cause bit stream parsing error.
