efbcfb13a7 Configuration in constructor of Goog CC.
Adding configuration of new GoogCcNetworkController to initializer, this
makes sure that it is properly initialized from the start. To achieve
this SendSideCongestionController waits until it has received the
necessary information to construct the object. This information should
be provided in the constructor for SendSideCongestionController in the
future.

45d9c1de9c Added congestion control functionality to pacer.
This adds the ability to the pacer to apply a congestion window by
tracking sent data. This makes it more reliable when the congestion
window is small enough to be filled at a high rate as there are less
thread context switches that might affect the timing and performance.

Outstanding data is not reduced by the pacer as it has no information
about acknowledged packet feedback. This is by design as the pacer would
also need to keep track of on which connection packets were sent or
received, requiring a larger, more complex, change to the pacer.

dae6aad6e7 Providing bitrate constraints in SSCC constructor.
This ensures that SendSideCongestionController is always initialized
with starting bitrate and bitrate limits.

8493594dc2 Cleanup of TransportFeedbackObserver interface
The GetTransportFeedbackVector() method is only used in tests, and they
can access the class directly anyway. Keeping it is adding code bloat
and is also making upcoming refactoring more difficult.

a06e919b9f Removing interface to access pacer via SSCC.
SSCC was accessing the pacer just to report values back to
RtpTransportControllerSend which already owns the pacer.
This CL moves those access methods.

To make RtpTransportControllerSend simpler, Call is made
responsible to keep track of network status used only as a
condition for report the pacer queuing delay.

0f9d9a9a12 Removed unused DeRegisterNetworkObserver.
DeRegisterNetworkObserver is not used, since
RtpTransportControllerSend owns the thread on which
SendSideCongestionController runs it would not be safe to allow it to be
called from outside. Deregistration should be done by destroying
RtpTransportControllerSend.

In the future, the RegisterObserver functions should be removed as well,
in favor of providing the observer in the constructor. This requires
breaking a circular dependency between RtpTransportControllerSend and
Call.

56da2f7868 Added unit tests for new congestion controller.
This CL activates unit tests for the task queue based send side
congestion controller that will replace the current one in the future.

To be able to have the tests run side by side with the tests of the old
congestion controller, the old tests have been prefixed with "Legacy".

This CL also contains some minor fixes to the new congestion controller
code.

This makes it easier to have the new and the old send side congestion
controller side by side. This namespace is only temporary. As soon the
new task queue based congestion controller is fully functional, the old
will be deprecated and removed together with the temporary namespace.

To be able to safely move over to the new code, the revised
code is added alongside the old code. Most of the files added
in this CL are more or less direct copies of the previous code.

This new version of send side congestion controller will be
activated under a field trial in a followup CL.
