When congestion window is used, two different mechanisms can currently
update the outstanding data state in the pacer:
* OnPacketSent() withing the pacer itself, when a packet is sent
* UpdateOutstandingData(), when RtpTransportControllerSend either:
a. Receives an OnPacketSent() callback (increase outstanding data)
b. Receives transport feedback (decrease outstanding data)
This creates a lot of calls to UpdateOutstandingData(), more than one
per sent packet. Each requires locking and/or thread jumps. To avoid
that, this CL moves the congestion window state to
RtpTransportController send - and we only post a congested flag down
the the pacer when the state is changed.
The only benefit I can see is of the old way is we prevent sending
new packets immedately when the window is full, rather than in some
edge cases queue extra packets on the network task queue before the
congestion signal is received. That should be rare and benign.
I think this simplified logic, which is easier to read and more
performant, is a better tradeoff.

This move the functionality of applying the lower bound of a network estimate to AimdRateControl::ClampBitrate instead of ChangeBitrate.
The purpose is to be able to also clamp probe estimates set by AimdRateControl::SetEstimate as well.

The VideoEncoderFactoryTemplate takes encoder implementations as template arguments, making it possible to easily implement a VideoEncoderFactory only using the implementations required for the particular application. This will replace the BuiltinVideoEncoderFactory.

This patch just refactors creation of P2P transport channel,
pushing down the IceTransportInit object rather than decomposing
it going down.
The IceTransportInit object will in subsequent patches be
extended with a field trial container.
Reason for splitting patch into this and subsequent is
to allow changes to internal factories.

Create a server using:
./data_channel_benchmark --server --port 12345
Start the flow of data from the server to a client using:
./data_channel_benchmark --port 12345 --transfer_size 100
The throughput is reported on the server console.
The negotiation does not require a 3rd party server and is done over a
gRPC transport. No TURN server is configured, so both peers need to be
reachable using STUN only.

absl::string_view across the WebRTC code base.
This CL adds absl::string_view versions of the OnLogMessage functions in
rtc::LogSink. The const std::string& versions are kept for now since
downstream clients use subclasses of LogSink and need to be migrated

The TQ Pacer schedules delayed task according to target time of
PacingController. It drains all valid ProcessPackets() in single loop,
denies retired scheduled tasks, and round up the timeout to 1ms.
This CL also improves packet size estimation in TQ Pacer by removing
zero initialization, and introduces `include_overhead_` configuration.
Tests:
1. webrtc_perf_tests: MaybeProcessPackets() calls
2075147 -> 2007995
2. module_unittests: MaybeProcessPackets() calls
203393 -> 183563
3. peerconnection_unittests: MaybeProcessPackets() calls
66713-> 64333
