Substantial restructuring of the way we estimate
the rate of decay in prediction quality and determine
the arf interval and amount of boost used.

Also other changes to support moving to a lower first pass
Q which exposes some new features and allows us to better
distinguish genuinely static blocks from low motion or noisy
blocks.

Net gains now visible on all the test sets with std-hd PSNR up
1.87%. There are still some bad outlier cases but most of these
are low motion or slide show type content where the metrics
are already high at any given rate. The best + case is up by
more than 10%.

The decoder performance improved up to 1% for the
test clips used.

Use the right return values - vadd_s64 returns int64x1_t, not
a normal int64_t.

The ARF frame should always be the same size as the
native resolution of the input frames.

It will be scaled to the required resolution at
encode time.

This commit makes the encoder to use non-zero mode threshold for
NEARESTMV modes. The runtime for test clips of speed 3 is reduced
by about 1%.

If the partition block is skippable, which means no coefficients
for Y, U, and V planes, its skip flag is set to 1. No quality
change (verified by borg tests), and no noticeable speed change.

Merge "vp8/vp9: neon: msvc: move the 'ifdef _MSC_VER' bit to vpx_ports/mem.h.                      fix compiling warning."

Libvpx was memseting every external frame buffer before decode. This
was to work around a valgrind issue in our C loop filter. Most of
the time this was not needed and we have noticed some significant
performance loss on some platforms. Now we require the application to
zero out the buffers if it is using external frame buffers.

This commit enforces ARF validation check for compound inter modes.
It avoids potential access to ARF in the encoding process if it
is not allowed.

The valid reference frame check in sub8x8 rate-distortion
optimization search has been included in the ref_frame_skip_mask
scheme. This commit removes the later further validation checks
that are not in effect.
