When the perceptual AQ mode is enabled, cap the ARF boost to 2.5x
of the regular frame. This allows more consistent frame quality
across consecutive frames and sufficient bit rate allocation at
frame level for AQ mode.

Note that when using --disable-runtime-cpu-detect the developer
must keep in mind what devices the library will be run on.

arm builds require too many tweaks to keep up with changes
to the ndk. Recommend ndk-build instead.
Update documentation and drop --sdk-path references. If
--enable-external-build is used instead we do not need the compiler
path.

Values of mb_smooth_pct and mb_av_energy have been updated
correctly in vp9_rc_get_second_pass_params for higher layer
ARF frames.

Add a macro to to exclude VP9 specific assembly files from build if VP9
is not configured. This would otherwise cause a linking error for VP8
only builds.

Trap the case where we end up with two short GF only groups just
before a key frame. For example, if the KF is 22 frames away
we are better doing one ARF group of size 16 followed by a GF
only group of 6 than two GF only groups of size 11 (when
min_gf_interval is 12).

Mask the values to show that we only want to store 1 byte. Switch
to lowercase ff since it's more prevalent in the file.

Support the potential frame scaling use case. The operation flow
now allows the codec to allocate the memory buffer only when
perceptual AQ mode is enabled.

clang 7 integer sanitizer warns on unsigned->signed conversions when

clang 7 integer sanitizer warns about storing any int16_t value
where the high bit is 1. Treated as an int, such number would
be positive. Treated as an int16_t, it is negative.

For screen content nonrd_pickmode: reduce
threshold to select 4x4 tx_size, under certain
conditions.

For nonrd-pickmode: pass the source variance and the
mode (intra/inter) to select tx_size, for better tuning.
Neutral change for video mode, speed 7.
Some quality improvement for screen content.

In nonrd_pickmode for intra modes: add tx_size selection
based on Y prediction signal for the bsize.
The tx selection is done in model_rd, same as inter-modes.
Existing code for intra mode was first setting a tx_size based
only on the bsize, and then in some cases in block_yrd
(during the loop over bsize in units of tx_size) the tx_size
may be set again if model_rd is called in block_yrd.
This CL separates out the tx_size setting (based on Y channel
prediction via model_rd), and then block_yrd is called once
for whole bsize. This allows for better tuning of the tx
selection for intra modes in future change.
Adjust threshold in svc datarate test.
Negligible/neutral change in psnr/ssim metrics
for speed 7 and 8, 1 layer and SVC mode.
