This CL accomplishes three things:
1) It enables feeding frame drop indications into the
AdaptedVideoTrackSource for the benefit of downstream projects.
2) Under zero hertz source delivery, a discarded frame ending a
sequence of frames which happened to contain important information
can be seen as a capture freeze. Avoid this by starting requesting
refresh frames after a grace period.
3) It changes the duration until first refresh frame requests on new
streams to three frame periods.

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.

This change makes it easier to propagate more information from the sink
to the video adapter, for example alignment requirements.

In several places VideoFrame::Builder is used to create a new VideoFrame
when intent is to change only one or two fields of a const VideoFrame&.
This approach is bad because each and every metadata field have to be
added to all the places.
Instead, this CL adds missing setters and refactors the code to use
full copy of a VideoFrame and update required fields only.
Along the way few actual bugs are fixed, e.g. when ColorSpace isn't copied
when frame rotation or buffer is cropped or converted.

This layer is not needed since the methods are thread safe, and the
classes those method touches (VideoBroadcaster, cricket::VideoAdapter)
are thread safe.
