- vp9_spatial_svc_encoder.c no longer supports the -m parameter that
  has been used in the example test. Tests using -m have been disabled.
- Added a basic test that appears to work as of commit
  3249f26f.
- Minor style clean up.

- Split vpxdec wrapper function into vpxdec() and vpxdec_pipe().
- Remove hard coded --noblit and --summary arguments from
  the wrappers in favor of shifting off the first argument (the
  input file) and passing all remaining parameters to vpxdec.
- Add --noblit and --summary args to existing tests, and update the
  pipe input test to use vpxdec_pipe().

This patch allows the encoder to skip the search for partition
SPLIT, HORZ, VERT after the search for partition NONE is done
in RD optimization. It uses the first pass block-wise statistics
to make the decision. If all 16x16 blocks in the current partition
have zero motions and small residues from the frist pass statistics,
and it has small difference variance, further partition search is
skipped.

For speed 2 setting, experiments on general youtube clips show that
the speedup varies from 1% - 10%, 5% on average. On the performance
side in PSNR, derf 0.004%, yt -0.059%, hd -0.106%, stdhd 0.032%.

For hard stdhd clips:
park_joy_1080p, 502952 ms -> 503307 ms (-0.07%)
pedestrian_area_1080p, 227049 ms -> 220531 ms (+3%)

This feature is under the compilation flag CONFIG_FP_MB_STATS and
it is off in current setting.

* changes:
  make testdata: look for other variants of sha1sum
  make testdata: fail if a sha1 fails or is missing
  test-data.sha1: add missing checksums

Remove the variable that indicates the relative block index. This
is explicitly covered by the use of pc_tree.

This commit enables a chessboard pattern constrained partition
search for 720p and above resolutions. The scheme applies stricter
partition search to alternative blocks based on its above/left
neighboring blocks' partition range, as well as that of the
collocated blocks in the previous frame. It is currently turned
on at 16x16 block size level. The chessboard pattern is flipped
per coding frame.

The speed 3 runtime is reduced:
park_joy_1080p, 652832 ms -> 607738 ms (7% speed-up)
pedestrian_area_1080p, 215998 ms -> 200589 ms (8% speed-up)

The compression performance is changed:
hd     -0.223%
stdhd  -0.295%
