in the sub_pixel_*variance* function the dst is aligned to 16 bytes and not
to 32 bytes - now load unaligned data

Fix the interaction between active map and reuse_inter_pred_sby. The
reuse_inter_pred_sby feature expects inter predictors to already be
built, but blocks with active map on skip this step.

in the function sad32x32x4d and sad64x64x4d the source is aligned to 16 bytes
and not to 32 bytes - the load is now unaligned.

Specifies the bit-depth, color sampling and colorspace
for intra only frames for profiles > 0
Also adds checks to ensure that profile 1 and 3 are
exclusively used for non 420 streams.

This commit adds a configure time option used to enable strict error
checking in decoder to make sure intermediate stage cofficients of
inverse transforms are within valid range of signed 16 bit integer.
For valid VP9 input streams, intermediate stage coefficients should
always stay within the range of a signed 16 bit integer. Coefficients
can go out of this range for invalid/corrupt VP9 streams. However,
strictly checking this range for every intermediate coefficient can
be a burden for decoder, therefore such validation is only enabled
with configure option --enable-coefficient-range-checking.

This commit integrates the fast transform and quantization process
into skip_recode scheme in the rate-distortion optimization loop.
Previously the fast transform and quantization process was only
enabled for non-RD coding flow.

This is needed to update the width/height and stride parameters
for the reference buffers that the denoiser uses.

When no more data is available, vpx_codec_decode should
be called with NULL as data and 0 as data_sz.
vpx_codec_get_frame iterates over a list of the frames
available for display. The iterator storage should be initialized
to NULL to start the iteration. Iteration is complete when this
function returns NULL.
Also change the unit test to conform to the api spec.

This patch allows the encoder to directly split the block
in partition search, therefore skip searching NONE. It
computes a score which measures whether 16x16 motion vectors
from the first pass in the current block are consistent with
each others. If they are inconsistent and we have enough Q
to encode, split the block directly, and skip searching NONE.
This feature is under flag CONFIG_FP_MB_STATS. In speed 2,
it further gives a speedup of 3-8% on sample yt clips as
compared to the previous version under the same flag. Overall,
the features under the flag will give 7-15% on typical yt
clips at up to 6000kbps data rate. The speedup at very high
data rate is not significant.
For hard stdhd clips:
park_joy_1080p @ 15000kbps: 504541ms -> 506293ms (-0.35%)
pedestrian_area_1080p @ 2000kbps: 326610ms -> 290090ms (+11.2%)
The compression performance using the features under the flag:
derf: -0.068%
yt: -0.189%
hd: -0.318%
stdhd:-0.183%
To use the feature, set CONFIG_FP_MB_STATS and turn on
cpi->use_fp_mb_stats.
