beabdcb498 Break VP8 temporal_layers dependency on libvpx.
This is in preparation for
https://webrtc-review.googlesource.com/c/src/+/36340

With these changes we can avoid some strange #ifdefs in the code
that uses temporal layers.

db9e9d5486 Make screenshare_layers frame dropper less aggressive
Try to use frame timestamps first if they look reasonable, otherwise
use realtime clock.
Also, lower limit from 90% of target to 85%.

27a457d172 Smoother frame dropping when screenshare_layers limits fps
This is a reland of https://webrtc-review.googlesource.com/34380

The main problem with that CL was that we used frame timestamps as basis
for frame dropping, but those might not be continuous or even populated
in some circumstances.

Additionally, I found that the bitrate was off since the encoder does
not not take the dropped frames into account, so if we drop every other
frame continiusoly, the bitrate sent will be around half of the target.

Patch set 1 is the original CL, subsequent patch sets cotains fixes.

afb3fc3558 Revert "Smoother frame dropping when screenshare_layers limits fps"
This reverts commit 28a06b16cc.

Reason for revert: Causes some unexpected perf changes.

Original change's description:
> Smoother frame dropping when screenshare_layers limits fps
> 
> Currently, when input fps is higher than the configured target fps in
> screenshare_layers, we drop frames with the help of a rate tracker using
> a one second sliding window. This is not optimal.
> For instance, given a 5fps limit and a 30fps capturer, the window will
> not be saturated until we have added the first 5 frames. Then we will
> drop all frames until the oldest one drops out, at which point we can
> immediately fill it's place. This results in quick 5 frame bursts every
> second.
> 
> In addition to rate tracker, also set a limit on minimum interval
> required between input frames, based on target frame rate.

28a06b16cc Smoother frame dropping when screenshare_layers limits fps
Currently, when input fps is higher than the configured target fps in
screenshare_layers, we drop frames with the help of a rate tracker using
a one second sliding window. This is not optimal.
For instance, given a 5fps limit and a 30fps capturer, the window will
not be saturated until we have added the first 5 frames. Then we will
drop all frames until the oldest one drops out, at which point we can
immediately fill it's place. This results in quick 5 frame bursts every
second.

In addition to rate tracker, also set a limit on minimum interval
required between input frames, based on target frame rate.

13044c1b53 Reduce time between sync frames for temporal layers vp8 screensharing.
This is expected to result in a slight loss of overall quality, but
should offset by quicker switching between temporal layers with flaky
connections.

bf35298996 Implement temporal layers checkers for vp8
All frames are checked against hard-coded dependency graph 
using new helper class. It's invoked in RTC_DCHECK(). Only 
DefaultTemporalLayers are fully implemented in this CL, checker 
for ScreenshareLayers is not doing anything for now.

92ea95e34a Fixing WebRTC after moving from src/webrtc to src/
In https://webrtc-review.googlesource.com/c/src/+/1560 we moved WebRTC
from src/webrtc to src/ (in order to preserve an healthy git history).
This CL takes care of fixing header guards, #include paths, etc...
