This patch insures that the last byte of a chunk that contains a
valid superframe marker byte, actually has a proper superframe index.
If not it returns an error.
As part of doing that the file : vp90-2-15-fuzz-flicker.webm now fails
to decode properly and moves to the invalid file test from the test
vector suite.

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.
