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.

This commit makes the ZEROMV mode first in the search order to
ensure that the zero mv is always checked in the RTC coding mode.
It improves the average speed -6 compression performance by 0.3%
in both PSNR and SSIM at no visible speed change.

cm->frame_bufs[].idx values were made consistent in:
61c5e94 Use -1 consistently as invalid buffer idx
update the initialization in swap_frame_buffers() to match.
additionally:
- remove some shadowed variables in the former and marked them volatile

The high bit depth build failed while building for 32bit target.
The bugs were in vp9_highbd_subpel_variance.asm and
vp9_highbd_sad4d_sse2.asm functions. This patch fixed the bugs,
and made 32bit build work.

On rtc set:
speed 7 quality improves about 0.5%
speed 8 quality improves about 1.0%
Encoding time for speed 7 changes from 67804ms to 65889ms
Encoding time for speed 8 changes from 58659ms to 56808ms

After syncing the frame worker thread, avaiable thread count should
increase by 1 even the worker thread does not have displayable frame
to output.

Reuse the yv12_mb array to fetch the buffer pointers/strides
corresponding to the current reference frame.

This commit allows the encoder to account for additional chroma
plane costs in the mode decision process, if the current block
potentially contains significant color change. It improves the
visual quality at very low bit-rates.
The compression performance of dark720p is improved by 12.39% in
speed 6. For jimred at 150 kbps, the PSNR of V component (red)
increased by 0.2 dB, at the expense of about 5% increase in
encoding time. Note that for sequences where the chroma components
are fairly consistent, the encoding time increase is negligible.
On average the rtc set compression performance is improved by
1.172% in PSNR and 1.920% in SSIM.

This patch continues the work to remove frame_parallel_decoding_mode
requirement in VP9 multi-threaded tile decoder. In order to do that,
the frame counts associated to each thread need to be accumulated
together after the frame is decoded.

The original implementation had the following comment:
// Ignore mv costing if mvsadcost is NULL
However the current implementation does not allow for this.
If x exists then nmvsadcost must not be null.
This removes the only warning from -Wpointer-bool-conversion

The current multi-threaded tile decoder requires that the videoes
are encoded with frame_parallel_decoding_mode = 1. This requirement
is not necessary, and is better to be removed. This patch includes
the first part of the work.

1. Adjusted the threshold for coef update computation based on counts
of tx used, avoid coef update computation when count is low (<20)
2. Move sf->lpf_pick = LPF_PICK_MINIMAL_LPF to speed 8.
