If the img allocation fails the test used to crash before on
32 bit architecture. This patch uses null check on img in
FillFrame. Also, if the first frame initialization has not been
conducted VPX_CODEC_ERROR is expected to return rather than
VPX_CODEC_OK.

The issue was introduced by commit g7c43fb6. If current frame
is repeated from existing-ref pool, frame buffer ref counter
is not decreased, so buffer isn't released. Decoder fails being
unable to allocate new frame buffer at some point.
Added a test vector to verify that the condition will not
recur later. Test vector was generated by the code in this patch:

All changes are for spatial svc only.
1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
2. Use golden reference idx for spatial reference
3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
4. Add "auto-alt-refs" in svc options

thread: remove harmless race on status_ in End()
if a thread was still doing work when End() was called there'd be a race
on worker->status_. in these cases, however, the specific value is
meaningless as it would be >= OK and the thread would have been shut
down properly, but we'll check 'impl_' instead to avoid any potential
TSan/DRD reports.

This patch fixes bug 633:
https://code.google.com/p/webm/issues/detail?id=633
The first decoded frame does not have to be a keyframe,
it could be an inter-frame that is coded intra-only.
This patch fixes the handling of intra-only frames.
A test vector has also been added that encodes 3
intra-only frames at the start of the clip. The
test vector was generated using the code in the
following patch:

Before encoding a frame, calculate and store each 16x16 block's
variance of source difference between last and current frame.
Find partitioning threshold T for the frame from its variance
histogram, and then use T to make partition decisions.
Comparing with fixed 16x16 partitioning, rtc set test showed an
overall psnr gain of 3.242%, and ssim gain of 3.751%. The best
psnr gain is 8.653%.
The overall encoding speed didn't change much. It got faster for
some clips(for example, 12% speedup for vidyo1), and a little
slower for others.
Also, a minor modification was made in datarate unit test.

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.

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.

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.
