a36165c77b Final version of BBR, with tweaks made for WebRTC, major changes:
1) Entering PROBE_RTT when necessary.
2) Congestion window gain of 0.65 instead of constant 4 packets.
3) {1.1, 0.9} pair instead of {1.25, 0.75}
4) Recovery mode.
5) No reaction to losses due to Recovery mode's implementation.
6) Supports encoder.
7) A new test compiling most of the simulation tests.
8) Bucket for high gain phase, disabled by default.
9) Pacer specific to BBR.

1) Function responsible for receiving feedback, digesting data and deciding switch scenarios.
2) Function which enters Startup mode.
3) Function which exits Startup mode.
4) Function which calculates, whether or not full bandwidth is reached.

c8fa692ec4 Update includes for webrtc/{base => rtc_base} rename (1/3)
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'.

e75d96b5bd Revert of Test and fix for huge bwe drop after alr state. (patchset #13 id:320001 of https://codereview.webrtc.org/2931873002/ )
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.

0703856b53 Add SafeClamp(), which accepts args of different types
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. :-)

6dcdf10c76 This is an initial cl, which contains small amount of implemented functions, and large amount of unimplemented ones.
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.

c7bf32a110 Propagate packet pacing information to SenTimeHistory.
In order to not make this CL too large I have broken it down into at least two steps. In this CL we only propagate the pacing information part of the way:

webrtc::PacedSender::Process                        <--- propagate from here
webrtc::PacedSender::SendPacket
webrtc::PacketRouter::TimeToSendPacket
webrtc::ModuleRtpRtcpImpl::TimeToSendPacket         <--- to here
webrtc::RTPSender::TimeToSendPacket
webrtc::RTPSender::PrepareAndSendPacket
webrtc::RTPSender::AddPacketToTransportFeedback
webrtc::TransportFeedbackAdapter::AddPacket
webrtc::SendTimeHistory::AddAndRemoveOld            <--- goal is to propagte it here

7d2542623a Delete unneeded includes of base/common.h.
Bulk of the changes were done using

   git grep -l '#include "webrtc/base/common.h"' | \
     xargs sed -i '\,^#include.*webrtc/base/common\.h,d'

followed by adding back the include in the few places where it is
still needed, and in one case (pseudotcp.cc) instead deleting its use
of RTC_UNUSED.

5a388368a2 Implement Theil-Sen's method for fitting a line to noisy data (used in bandwidth estimation).
Theil and Sen's estimator essentially looks at the line through every pair of points and selects the median slope. This is robust to corruption of up to 29% of the data points.

Wire up new estimator to field trial experiment. Add unit and integration tests. Results are promising.

182e4a4aff Remove bitrate cap for AdaptiveVideoSource and increase other caps to 25 Mbps.
AdaptiveVideoSource is used in testing/simulations of the bandwidth estimator.

Nada's reaction to delay depends on the current bitrate and the configured max rate in a non-intuituve way. Increase the starting bitrate to compensate for the increased max bitrate. This is only used in unit tests.

f94ba462bc Update BWE_TEST_LOGGING_PLOT output format, and fix plot_dynamics.py script.
The new format for plot lines is PLOT <plot_no> <var_name>:<ssrc>@<alg_name> <time> <value>. The var_name is no longer prefixed by the context/tag (which most of the time was just the same as the test name.)

Update plot_dynamics.py script (which didn't work) to visualize the new BWE_TEST_LOGGING_PLOT lines.
