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

Add a speed feature to give the tighter partition search
range. Before partition search, calculate the histogram
of the partition sizes of the left, above and previous
co-located blocks of the current block. If the variance of
observed partition sizes is small enough, adjust the search
range around the mean partition size, which will be tigher.
The feature is currently turned on at speed 2. Experiments on
sample youtube clips show on average the runtime is reduced
by 3-7%.
For hard stdhd clips:
park_joy_1080p @ 15000kbps: 509251 ms -> 491953 ms (3.3%)
pedestrian_area_1080p @ 2000kbps: 223941 ms -> 214226 ms (4.3%)
The PSNR performance is changed:
derf: -0.112%
yt: -0.099%
hd: -0.090%
stdhd:-0.102%

- Fix nit: make test function definitions match test order.
- Fix nit: use elog instead of echo for env verification error.

When configuring the buffer make sure to set all the (now) required
fields. Use the canonical variables and match the style from vpx_scale.

runs the allocation may fail most regularly with mingw+wine.

- 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.

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.
