This change
- adds new type VideoTrackSourceConstraints expressing min/max FPS
constraints.
- adds new method VideoTrackSourceInterface::ProcessConstraints.
- adds new method VideoSinkInterface<>::OnConstraintsChanged.
- updates AdaptedVideoTrackSource and VideoBroadcaster to forward
the constraints to sinks.
- adds several unit tests for the added functionality.
- and finally, implements OnConstraintsChanged in VideoStreamEncoder.
Chromium will be updated in coming CLs to supply constraints set
through the MediaStream module.

Encoder info will be modified at runtime. In fact, we should reduce the
number of 'full' ReconfigureEncoder(). If only need subset of it at
runtime, consider handle it in VideoStreamEncoder::EncodeVideoFrame().
Consider two cases:
Re-configure scalers when encoder info changed. Consider two cases:
1. When the status of the scaler changes from enabled to disabled, if we
don't do this CL, scaler will adapt up/down to trigger an unnecessary
full ReconfigureEncoder() when the scaler should be banned.
2. When the status of the scaler changes from disabled to enabled, if we
don't do this CL, scaler will not work until some code trigger
ReconfigureEncoder(). In extreme cases, the scaler doesn't even work for
a long time when we expect that the scaler should work.
This CL aims to make scalers work properly when encoder info changed.

To fix this issue, this CL implements a bandwidth scaler which is used
for adjust resolution, this scaler will be used when QP based quality
scaler is not working due to untrusted QP reported by HW AVC encoder.

min_pacing:8ms, to avoid the situation where bursts of frames are sent
to the decoder at once due to network jitter. The bursts of frames
caused the queues further down in the processing to be full and
therefore drop all frames.

up, do as before and send all frames to the decoder to avoid building

Currently the implementation of FrameTransformers uses distinct,
incompatible types for recevied vs about-to-be-sent frames. This adds a
flag in the interface so we can at least check that we are being given
the correct type. crbug.com/1250638 tracks removing the need for this.
Chrome will be updated after this to check the direction flag and provide
a javascript error if the wrong type of frame is written into the
encoded insertable streams writable stream, rather than crashing.

The experiment WebRTC-PreStreamDecoders (aka Lazy decoder creation) has
investigated the benefit of only creating a subset of all decoders
during negotiation and the remaining decoders on demand.
This CL changes the default value to only create one decoder during
negotiation. This frees up hardware resources and reduces the SDP
negotiation time.

After a send stream is stopped, it can still be re-used and implicitly
restarted by activating layers. This change removes marking the flag
we use for async operations as 'not alive' inside Stop() and only doing
so when the send stream is stopped permanently.
The effect this has is that an implicit start via
UpdateActiveSimulcastLayers() will run and correctly update the states.
Before, if a stream had been stopped, the safety flag would prevent
the async operation from running.

And with:
git grep -l "RTC_DCHECK(false)" | \

With some manual changes to include "rtc_base/checks.h" where
needed.
A follow-up CL will remove assert() from Obj-C code as well
and remove the #include of <assert.h>.
The choice to replace with RTC_DCHECK is because assert()
is because RTC_DCHECK has similar behavior as assert()
based on NDEBUG.
This CL also contains manual changes to switch from
basic RTC_DCHECK to other (preferred) versions like
RTC_DCHECK_GT (and similar).
