I used a command like this to update the paths:
perl -pi -e "s/webrtc\/base/webrtc\/rtc_base/g" `find webrtc/rtc_base -name "*.cc" -o -name "*.h"`
The only manual edit is to add an include of webrtc/rtc_base/checks.h in
webrtc/modules/audio_device/android/opensles_common.h, which likely
was needed due to changed include paths due to 'git cl format'.

Reason for revert:
Resetting the estimate means that we need to start gathering data from scratch again. The combination of
1) DelayBasedEstimator not reacting to overuse unless there is a valid estimate of the acknowledged bitrate, and
2) AcknowledgedBitrateEstimator needing a significant amount of time/data to obtain an provide an estimate
causes poor performance in simulations/tests. It is not clear whether this will affect real networks negatively, but I suggest reverting this to be on the safe side.

While building Chrome with the VC++ 2017 /permissive- flag I got a
warning about a forward declaration of enum RateControlRegion. Untyped
forward declarations of enums are illegal because the compiler doesn't
know what size to make them. The only reason this forward declaration is
legal is because it isn't needed (the type is already defined).
This was found because /permissive- (or, equivalently for this purpose,
/w14471) incorrectly fires on this forward declaration even though it is
legal.

Specifically, just like SafeMin() and SafeMax() it handles all
combinations of integer and all
combinations of floating-point arguments by picking a
result type that is guaranteed to be able to hold the result.
This CL also replaces a bunch of std::min + std:max call pairs with
calls to SafeClamp()---the ones that could easily be found by grep
because "min" and "max" were on the same line. :-)

Code should implement BBR which is the congestion controlling algorithm. BBR tries to estimate two values bottle-neck bandwidth(bw) and round trip time(rtt),then use these two values to set two control parameters pacing rate(pacing_rate),the rate at which data should be sent and congestion window size (cwnd), cwnd is the upper bound for data in flight,data_in_flight <= cwnd at all time.
BBR has four modes:
1)Startup-ramping up throughput discovering estimated bw.
2)Drain-after Startup decrease throughput to drain queues.
3)Probe Bandwidth-most of the time BBR should be in this mode,
sending data at the rate of estimated bw, while sometimes trying to discover new bandwidth.
4)Probe Rtt-in this mode BBR tries to discover new rtt for the connection.
The key moment in BBR is when we receive feedback from the receiver,as this is the only moment which should effect our two estimators. At this moment all the switches between modes should happen, except switch to ProbeRtt mode (switching to ProbeRtt mode should happen when current min_rtt value expires).
This cl serves to emphasize the structure of Bbr, when switches happen and what key classes/functions should be implemented for proper functionality.

This target keeps track of .h the files under webrtc/modules/include/
that are not part of any target.
If a .h file is not part of a target the 'gn check' utility is not
able to spot if a target is missing a dependency because even if
it parses '#include' directives it is not able to find a target that
contains these headers.

Specifically, they handle all combinations of two integer and two
floating-point arguments by picking a result type that is guaranteed
to be able to hold the result. This means callers no longer have to
deal with potentially dangerous casting to make all the arguments have
the same type, like they have to with std::min() and std::max().
Also, they're constexpr.
Mostly for illustrative purposes, this CL replaces a few std::min()
and std::max() calls with SafeMin() and SafeMax().
