This commit introduces a new block match motion estimation
using integral projection measurement. The 2-D block and the nearby
region is projected onto the horizontal and vertical 1-D vectors,
respectively. It then runs vector match, instead of block match,
over the two separate 1-D vectors to locate the motion compensated
reference block.

This process is run per 64x64 block to align the reference before
choosing partitioning in speed 6. The overall CPU cycle cost due
to this additional 64x64 block match (SSE2 version) takes around 2%
at low bit-rate rtc speed 6. When strong motion activities exist in
the video sequence, it substantially improves the partition
selection accuracy, thereby achieving better compression performance
and lower CPU cycles.

The experiments were tested in RTC speed -6 setting:

The block partition rate cost should be updated when recursive
partition search is needed.

This commit adds a heuristic rate cost of reference frame to the
non-RD mode decision. It improves the compression performance of
speed -6 by 0.31% and speed -5 by 0.69%.

This enbale the encoder to set color space information for the input
video, so it is then coded in the output bitstream.

MODE_INFO struct was modified, and vp9_print_modes_and_motion_vectors()
didn't work anymore. This patch modified vp9_debugmodes.c so that
this function works again for debug usage.

This is to avoid redo the same calculation repeatly, and also allow
easier adjustments for further experiments.

This commit shall have no effect on quality/compression.

Note: This feature is still in development.

Add an option for the encoder to decide the resolution
at which to encode each frame.

Each KF/GF/ARF goup is tested to see if it would be
better encoded at a lower resolution. At present, each
KF/GF/ARF is coded first at full-size and if the coded
size exceeds a threshold (twice target data rate) at
the maximum active Q then the entire group is encoded
at lower resolution.

This feature is enabled in vpxenc by setting:
  --resize-allowed=1

In addition, if the vpxenc command line also specifies
valid frame dimensions using:
  --resize-width=XXXX & --resize_height=YYYY
then *all* frames will be encoded at this resolution.

This commit fixes the sub block partition size used in
fill_mode_info_sb. Previous implementation effectively disabled
the rectangular block sizes. This commit resolved this issue.

This will fix the frame parallel decode hang on windows
due to not enough semaphores.

This will also make the frame parallel decode safer as
the number of frame buffers could only support maximum
8 threads.
