- First pass encoding time reduces ~10.9% on i7-6700
  at 100 frames, 1080p.
- avx2 works for coeff number >= 8 cases; coeff number < 8
  case will be implemented by sse2.
- Unit test is added type B/FP/DC.

Previously, for block >=8x8, and tx < 8x8,
we skipped setting the early-exit flag in block_rd_txfm() because
distortion for sub8x8 tx block is from MSE but reference (best)
is from daala-dist.
However, not setting early-exit flag turned out to be the reason
for a regression in MSE probe mode of daala-dist because
it loses the chance to set rd_stats properly.

On the other hand, there is still a small regression, say 0.05% psnr bd-rate,
which seems to occur in the case that a tx block in a partition has chosen
the skipped rd_cost since it is smaller than non-skip rd_cost and
set the early-exit flag to 0 (so, not exit), but the daala-dist applied
to the whole partition cannot access the same info but can choose from
two kinds of rd_costs:
1) all tx blocks are skipped (even if a tx block has non-zero coeff) and 0 bits
2) sum of final distortion of all tx blocks (i.e. non-zero coeff decoded)
and bits to encode coeffs.

Adds an option bit in the bitstream syntax to allow chroma to
have restoration tilesize that is coupled to luma based on
subsmapling of the color components.

This is meant to ease encoder hardware implementation.

cb4x4 itself should not require these sizes.

This simplifies compatibility with other experiments, since we can
first make them work with cb4x4 (which is now on by default), and
then worry about chroma_sub8x8 and chroma_2x2 (which is not) in
separate steps.

Encoder and decoder output should remain unchanged.

When writing the compressed header, prob_diff_update() was called
for compound_type_prob[] for every defined block size, even though
luma never uses block sizes smaller than 4x4.

This fixes is_any_masked_compound_used() and
is_interinter_compound_used() to properly return 0 for chroma-only
block sizes, and then uses these functions to guard the probability
updates in write_compressed_header() and read_compressed_header(),
the same way the actual compound type values are guarded in
read_inter_block_mode_info() and pack_inter_mode_mvs().

Without tempmv-signaling configured, using the previous frame's MVs
requires that the last frame was a show frame. With tempmv-signaling
configured, cm->show_last_frame is not checked when calculating
use_prev_frame_mvs. This patch adds that check and resolves mismatches
seen with random resizing and random superres.

Includes a couple fixes too - cm's last_width, last_height, and
last_show_frame were updated under different conditions. Now they're all
updated at the same time.

The encoder and decoder will now use the 16-bit (high-bitdepth)
coding path, regardless of the encoding profile.

This is a step towards the removal of the 8-bit (low-bitdepth)
coding path (which remains compile-checked at the moment).

This is enabled via:
$ cmake path/to/aom -DBUILD_SHARED_LIBS=1

Currently supports only Linux and MacOS targets. Symbol visibility
is handled by exports.cmake and its helpers exports_sources.cmake
and generate_exports.cmake.

Some sweeping changes were required to properly support shared libs
and control symbol visibility:

- Object libraries are always linked privately into static
  libraries.
- Static libraries are always linked privately into eachother
  in the many cases where the CMake build merges multiple library
  targets.
- aom_dsp.cmake now links all its targets into the aom_dsp static
  library target, and privately links aom_dsp into the aom target.
- av1.cmake now links all its targets into the aom_av1 static library
  target, and privately links in aom_dsp and aom_scale as well. It
  then privately links aom_av1 into the aom target.
- The aom_mem, aom_ports, aom_scale, and aom_util targets are now
  static libs that are privately linked into the aom target.
- In CMakeLists.txt libyuv and libwebm are now privately linked into
  app targets.
- The ASM and intrinsic library functions in aom_optimization.cmake
  now both require a dependent target argument. This facilitates the
  changes noted above regarding new privately linked static library
  targets for ASM and intrinsics sources.
