- 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
3249f26ff8.
- 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.

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%

On a Nexus 7, vpxenc (in realtime mode, speed -12)
reported a performance improvement of ~16.7%.

currently the only way to know if multiple alt-refs are enabled is to
inspect the encoder instance.
this reduces the size of the allocation by 75% when not using multiple
alt-refs

This commit replace the repetitive retrieve of max and min allowed
partition from speed_feature with local variables max_size and
min_size.

The get_chessboard_index() used to call the entire VP9_COMMON
struct pointer to retrieve the chessboard pattern index. This cl
makes it call the frame index directly.
