bf40b42af5 Modified Simulation Framework Jitter Model.
Using a right-sided (absolute value), truncated gaussian distribution originally with zero mean.

Currently truncated at x = 3 * std_dev.

Added expected value computation.

Modified jitter unittests accordingly.

9c261f2d13 Supports logging for dynamic and histogram plots on Simulation Framework.
---- Dynamic receiving rate.
---- Dynamic packet-loss.
---- Dynamic objective function.
---- Dynamic available capacity.
---- Dynamic available capacity per flow.
---- Average delay Histogram with standard deviation or 5th/95th percentiles.
---- Average bitrate Histogram with error bars.
---- Optimal average bitrate dashed line.
---- Average packet-loss Histogram.
---- Total objective function Histogram.

Added media Pause/Resume methods to Video and TcpSender.
Modified LinkedSet: computing GlobalPacketLossRatio even if packet's sequence_number overflows.
Added small randomization to frame send times, modified bwe_test_framework_unittest accordingly.
Taking offset time into account for plotting.

Added nada_unittests.
Added bwe_unittests.
Added a RateCounter to BweReceiver (replaced ReceivingRate)
Added LossAccount.

Fixed NadaBweReceiver issue: using sender_timestamp instead of creation_time.
Fixed memory leaks.
Fixed int division rounding issues.

Supporting plots on bandwidth Estimators:
Logging received packet information on on SubClassesBweReceiver::ReceivePacket
Updating RateCounter, updating packet loss account and relieving LinkedSet when necessary.

c81591d63f NADA's proposal from Cisco.
The implementation of this proposal is in progress.
More unittest will be added.
Sender side is being implemented.
Some constants need to be tuned.

4346d92578 Use SendTimeHistory to keep track of send times in simulations.
Use SendTimeHistory to keep track of send times in simulations.
Keep piggybacking send time in PacketInfo for now but use history in
order to be more in line with what we expect to do.

Landing this for sprang@. Original CL: https://review.webrtc.org/43559004/

7663684258 Implement the Nada rmcat proposal within the simulation framework.
This first CL focuses only on the bandwidth estimation parts of NADA, and doesn't contain the rate smoothing. It is still missing slow start functionality.
