- Remove vpxdec and vpxenc from the exclude list.
- vpx{dec,enc}.sh: Updates to support finding their executable when
LIBVPX_BIN_PATH is setup for the examples.
- tools_common.sh: New library function, vpx_tool_path(). Provides
support for finding the exectuables in vpx{dec,enc}.sh.

According to the current API spec we need to call vpx_codec_encode() until
vpx_codec_get_cx_data() returns NULL.

Explicitly makes the fileptr null when close source is called
on a temporary file. This avoids a valgrind error.

On key frame, will always start with normal denoising mode,
but based on a computed noise metric (normalized mse on source diff)
may switch to aggressive mode (and back down again).

Modify zero_mv bias condition to include check that "closest" reference is last_frame.
This is needed for temporal layers, where the last_frame is not always the closest reference.
Also, constain zeromv_count to be for last_frame reference.

In the current implementation of the encoder,
frame buffers may come from the wider set of
12 such buffers, and is not restricted to the
8 allowed as reference frames. This is only
an implementation detail and does not affect
the constraint of having a total of 8 reference
buffers overall.

At --good and speed 3 or above for resolution less than 720p. This
disables the tests for 64x64 intra prediction modes. Encoding time
reduction is about 1%.

The test to determine if the mode info buffers need
to be resized when the frame size changes was
incorrect, as per bug 837.
By storing the size of the allocated data structure,
a simple test determines whether to allocate more
memory when the frame size changes.

In the encoder, current_video_frame is used in a couple of places to
decide encoding strategy, this commit replaces with more appropriate
variables.

This commit moves the simplified coefficient probability model
and costing update to speed 4, and turns on chessboard pattern
mode search for sub 720p sequences. The overall coding performance
of speed 3 is improved:
derf 0.889%
stdhd 1.744%
The speed 3 runtime for test sequences are improved:
bus cif at 1000 kbps 9823 ms -> 9642 ms
pedestrian 1080p 2000 kbps 189559 ms -> 183284 ms

This commit enables the encoder to skip NEARMV and ZEROMV if the
above and left blocks have identical reference frame, and the
current reference is different from that. It reduces the runtime
of speed 3 for test sequences:
bus cif at 1000 kbps 10064 ms -> 9823 ms
pedestrian 1080p at 2000 kbps 193078 ms -> 189559 ms
The compression performance is changed by
derf -0.085%
stdhd -0.103%

This commit allows the encoder to check the above and left neighbor
blocks' reference frames and motion vectors. If they are all
consistent, skip checking the NEARMV and ZEROMV modes. This is
enabled in speed 3. The coding performance is improved:
pedestrian area 1080p at 2000 kbps,
from 74773 b/f, 41.101 dB, 198064 ms
to 74795 b/f, 41.099 dB, 193078 ms
park joy 1080p at 15000 kbps,
from 290727 b/f, 30.640 dB, 609113 ms
to 290558 b/f, 30.630 dB, 592815 ms
Overall compression performance of speed 3 is changed
derf -0.171%
stdhd -0.168%

The function is called only once, right after all stats counters are
reset to 0. Therefore all the computations have zero effect on return
values. This commmit to removed those effectless code.

check that bitrates increase with cqlevel at global test case teardown,
rather than after each individual test case. this allows the tests to be
run out of order with --gtest_shuffle.

Reinstates an assignment to prevent an asan failurere on google3.
Not sure why the failure happens. This was removed in a recent patch
