This support is needed if there is a big delay between the creation of
frames and the time they are delivered to the WebRTC C++ layer in
AndroidVideoTrackSource. This is the case if e.g. some heavy video
processing is applied to the frames that takes a couple of hundred
milliseconds. Currently, timestamps coming from Android video sources
are aligned to rtc::TimeMicros() once they reach the WebRTC C++ layer in
AndroidVideoTrackSource. At this point, we "forget" any latency that
might occur before this point, and audio/video sync consequently
suffers.

This CL adds tests that are primarily targeting
VideoFrame.Buffer.toI420() and cropAndScale(), but includes the whole
chain for YuvConverter, GlRectDrawer, and VideoFrameDrawer.
It also includes a couple of fixes to bugs that were exposed by the new
tests.

This CL removes the use of the @JNINamespace annotation and instead
sets the correct JNI namespace in the build file.

Adds Android native API for creating VideoTrackSourceInterface objects
that can be fed frames using VideoCapturer.CapturerObserver.
NativeCapturerObserver is moved out of VideoSource because it will now
be used without a VideoSource. It now takes a pointer to
AndroidVideoTrackSource directly instead of VideoTrackSourceProxy.
VideoSource and NativeCapturerObserver JNI code is moved away from
androidvideotracksource.cc to their own files. This allows using
AndroidVideoTrackSource independently.
