For the case when the number of temporal layers > 1,
the buffer levels (starting/optimal_buffer_level,
and maximum_buffer_size) were not scaled properly.

In vp9_update_layer_context_change_config():
when setting the layer-buffer levels, fix is to scale
the layer-target_bandwidth by the target_bandwidth
(which is the full stream bandwidth) instead of the
spatial_layer_target.

This is needed because prior to the call
vp9_update_layer_context_change_config(), set_rc_buffer_sizes()
is called which sets the buffer levels based on target bandwidth
(which is the full bandwidth for the SVC stream).

This fix properly sets the layer-buffer levels based on the
layer-bandwidth, and leads to better rate targeting.

Small/neutral change in avgPSNR/SSIM metrics on RTC set.

Control Flow Integrity [1] indirect call checking verifies that function
pointers only call valid functions with a matching type signature. This
change eliminates function pointer casts to make libvpx CFI-safe.

For reference frames: enable scale partition for
superblocks with low source sad or if bsize on lower-resoln
is at least 32x32.

Keep feature disabled for base temporal layer.

Small regression in avgPNSR/SSIM metrics, ~0.5-1%.
Speedup ~2-3% on mac for SVC (3 spatial/3 temporal layers) at speed 7.

When allow_partition_search_skip  is set the two pass code
can optionally skip the partition search in the rd loop if the image
appears static (based on selection of 0,0 motion).

Unfortunately 0,0 motion does not necessarily mean that there are
no meaningful changes or that motion or intra modes will not be selected
in the second pass.

Disabling "allow_partition_search_skip" may hurt the encode speed a little
for a small number of clips but can have a big impact on compression.
The most notable example of this in our test sets is "bridge_close_cif"
where this change gives a gains of 18%, 12% and 16% in opsnr, ssim and
psnr-hvs.

Enable partition copy on boundary and scale blocks along the boundary.
Rename copy_partition_svc to scale_partition_svc.

Do not copy if the block crosses the boundary.

The decay accumulator clause covers similar ground to the
new clause that tests the accumulated second reference error
so it has been removed to reduce complexity.

Change-Id: I4ec1cce32d72bd4ee463ad7def2831a68447d525

Add a clause to the breakout test for alt ref groups that
examines the size of the accumulated second reference
frame error compared to the cost of intra coding.

This clause causes a reduction in the average group length for many
clips. Alongside the change to the group length the minimum
boost is increased.

On balance the results are positive for psnr and psnr-hvs
but is negative for ssim/fast ssim for the smaller image formats.

Strong gains on some harder clips (eg ducks take off (midres) ~20%,
husky (lowres) 6-17%. Most of the negative cases are lower motion
clips. Subsequent patch hopefully will help with those.

Fix/cleaup the conditioning for usage of the reuse-lowres
partition feature.

Replace the non-reference condition with the top temporal
layer, and put this condition in the speed feature.

This prevents doing update_partition_svc() on every
VGA frame, instead it will now only do update for VGA in
the top temporal layer frames.

Also this makes it easier to test/enable this feature
for lower layer temporal frames.

For new VP9 only content type adjust  the rate distortion and ARF
filter based on the relative spatial variance of the source and
reconstruction.

In regards to the RD loop the method favors modes where the
reconstruction variance is similar to the source variance. However it
is currently only applied to regions where the source variance is quite
low.

For very low variance blocks it applies a further bias against intra
coding and large prediction block sizes (the later in particular limit
the usefulness of the loop filter).

The final part of this change is to lower the strength of the ARF
filter for blocks where the source has very low spatial variance, to
encourage some low amplitude texture or noise to pass through
the filter.

This change improves the retention of film grain and fine noise /
texture in spatially flat regions, but as expected causes a significant
drop in PSNR on many clips. This is to be expected because similar
but misaligned noise or texture will give a lower PSNR than a flat
noise free reconstruction. However, it is worth noting that most clips
show a strong gain in FAST SSIM.

The features are enabled on the vpxenc command line by setting
--tune-content=film.

VPX_ENCODER_ABI_VERSION bumped for this change and cvbr.

For choose_partitioning (speed >= 6): avoid computation
of minmax variance for non-reference frames in SVC.

Existing condition only avoided this for speed >= 8.
Combine that existing logic with non-reference condition.

neutral change on avgPSNR/SSIM metrics.
