vp9: Allow for disabling loopfilter per spatial layer
For SVC: add parameter to the control SET_SVC_PARAMS to
allow for disabling the loopfilter per spatial layer.
Note this svc setting will override the setting via
VP9E_SET_DISABLE_LOOPFILTER (which should only be used
for non-SVC).
Add unittest to handle both SVC (spatial or temporal layers)
and non-SVC (single layer) case.

Accumulate frame tpl stats and pass through rate control api
Tpl stats is computed at the beginning of encoding the altref
frame. We aggregate tpl stats of all blocks for every frame of
the current group of picture.
After the altref frame is encoded, the tpl stats is passed through
the encode frame result to external environment.

vp8: Remove sched_yield on POSIX systems
libvpx does sched_yield() on Linux. This is highly frowned upon these
days mainly because it is not needed and causes high scheduler overhead.
It is not needed because the kernel will preempt the task while it is
spinning which will imply a yield. On ChromeOS, not yielding has the
following improvements:
As you can see, there is a 5% drop in the scheduler's CPU utilization.
2. power_VideoCall test results:
There is a 3% improvement on max video FPS, from 30 to 31. This
improvement is consistent.
Also note that the sched_yield() manpage itself says it is intended
only for RT tasks. From manpagE: "sched_yield() is intended for use
with real-time scheduling policies (i.e., SCHED_FIFO or SCHED_RR)
and very likely means your application design is broken."

This currently is a warning, but the tree should be clean now in the
default x86-64 configuration so we can use it to prevent regressions and
find any remaining issues in other configurations.

vp9-rtc: Add control to disable maxq on overshoot
Add encoder control to disable feature to increase Q
on overshoot detection, for CBR. Default (no usage
of the control) means the feature is internally enabled.
Add the control to the sample encoders, but keep it
disabled as default (set to 0, so feature is on).

In other words, the `#` character is evaluated first when parsing
Makefiles, causing the rest of the line to become a comment. The effect of
this is that paths that contain embedded `#` symbols are not handled
properly in the vpx build system.
To test this change, clone vpx to a directory containing a `#` symbol and
attempt a build. With this change, it worked for me on Fedora 31, however
without the change the build failed.
