Another project in ChromeOS is using these files. To make libvpx
rolls simpler, add these files back unitl the other project removes
the dependency.
crbug.com/387246 tracking bug to remove dependency.

When decoding in serial mode, there will be only
one FrameWorker doing decoding. When decoding in
parallel mode, there will be several FrameWorkers
doing decoding in parallel.

The code properly catches an invalid stream but seg faults instead of
returning an error due to a buffer not having been initialized. This
code fixes that.

This patch adds a mechanism for insuring error checking on invalid files
by creating a unit test that runs the decoder and tests that the error
code matches what's expected on each frame in the decoder.
Disabled for now as this unit test will segfault with existing code.

Added missing 'break;'s
Also included other minor changes, mostly cosmetic.

The test for this is in test vector code ( show existing frames will
fail ). I can't check it in disabled as I'm changing the generic
test code to do this:

This commit allows the key frame to search through more prediction
modes and more flexible block sizes. No speed change observed. The
coding performance for rtc set is improved by 1.7% for speed -5 and
3.0% for speed -6.

A superframe is a bunch of frames that bundled as one frame. It is mostly
used to combine one or more non-displayable frames and one displayable frame.
For frame parallel decoding, libvpx decoder will only support decoding one
normal frame or a super frame with superframe index.
If an application pass a superframe without superframe index or a chunk
of displayable frames without superframe index to libvpx decoder, libvpx
will not decode it in frame parallel mode. But libvpx decoder still could
decode it in serial mode.

This breaks the profile 1 bitstream.
Don't force non420 uv transform size to 1/4 y size. In the 4:2:0 case the
chroma corresponding to a luma block is 1/4 its size. In the 4:4:4 case
chroma and luma planes are the same size. Disallowing larger transforms
can result in a loss of compression efficiency and is inconsistent.
For sub-8x8 blocks only average corresponding motion vectors.
4:2:0 and profile 0 behavior remains unchanged.

- Rename build_targets to build_framework
- Add functions for creating the vpx_config shim and obtaining
preproc symbols.

Speed 6 uses small tx size, namely 8x8. max_intra_bsize needs to
be modified accordingly to ensure valid intra mode checking.
Borg test on RTC set showed an overall PSNR gain of 0.335% in speed
-6.
This also changes speed -5 encoding by allowing DC_PRED checking
for block32x32. Borg test on RTC set showed a slight PSNR gain of
0.145%, and no noticeable speed change.

This is the first step to rework the rate-distortion modeling used
in rtc coding mode. The overall goal is to make the modeling
customized for the statistics encountered in the rtc coding.
This commit makes encoder to perform rate-distortion modeling for
DC and AC coefficients separately. No speed changes observed.
The coding performance for pedestrian_area_1080p is largely
improved:
speed -5, from 79558 b/f, 37.871 dB -> 79598 b/f, 38.600 dB
speed -6, from 79515 b/f, 37.822 dB -> 79544 b/f, 38.130 dB
Overall performance for rtc set at speed -6 is improved by 0.67%.
