VP9E_SET_EXTERNAL_RATE_CONTROL
One can assign an external library using the control flag,
VP9E_SET_EXTERNAL_RATE_CONTROL.
The args alongside the control flag should be of type char**.
args[0]: char* points to the path of rate control library
args[1]: char* points to the config of the rate control library.

configure: add darwin20 support
this release will have arm64 and x86_64 support. in the future it might

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."

googletest: enable failure on uninstantiated tests

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).
$ make
foo
'foo
"foo
foo#bar
'foo#bar'
"foo#bar"
make: *** No targets. Stop.
$ make -v
GNU Make 4.2.1
```
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.

Fix to reset RC for temporal layers: the

temporal layers will be reset (when max-q is used

Fix ObserveFirstPassMotionVectors()
1) Use kRefFrameTypeNone in the unit test
2) Reset mv_info in fp_motion_vector_info_init
3) Call fp_motion_vector_info_init() in first_pass_encode()
4) Set mv_info for intra frame.
5) Set mv_info with zero mv as default for inter frame
6) Remove duplicated fp_motion_vector_info in encode_frame_info
Store motion vectors for each 16x16 block found in the first pass
motion search.
Provide an api "ObserveFirstPassMotionVector()" in SimpleEncode

vp9-svc: Fix to setting frame size for dynamic resize
For svc with dynamic resize (only for single_layer_svc mode),
add flag to indicate resized width/height has already been set,
otherwise on the resized/trigger frame (resize_pending=1), the
wrong resolution may be set if oxcf->width/height is different
than layer width/height in single_layer_svc mode.
Fix two bugs reported by clang when enable msa optimizatons:
1. clang dose not support uld instruction.
2. ulw instruction will result in unit cases coredump.
1. Adjust variable type to match clang compiler.
Clang is more strict on the type of asm operands, float or double
type variable should use constraint 'f', integer variable should
use constraint 'r'.
2. Fix prob of using r-value in output operands.
clang report error: 'invalid use of a cast in a inline asm context
requiring an l-value: remove the cast or build with -fheinous-gnu-extensions'.

vp9: Fix to use last_q for resize check
For temporal layers resize is only checked
on the base/TL0 frames. So rc->last_q should be used,
which because rc is in the layer context, rc->last_q
will correspond to the qindex on last TL0 frame.
In the previous code cm->base_qindex was used, which
would correspond to qindex on last encoded frame, which
is not TL0 when temporal_layers > 1.
