7702c8ac04 Fix SendSideBweWithOverhead using new pacer code path.
This field trial was read in RTPSender, and the altered packet size
passed along to the pacer. Now, the pacer packet queue looks directly
at the packet instance, so it needs to be aware of the experiment flag
in order to make the right decision.

425d6aaa4c Add RtpPacketPacer interface for pacer control
The PacedSender is being reworked and will need an interface so we can
inject different implementations of it.

This CL introduces a new RtpPacketPacer interface inside the pacing
module. This interface handles the details of _how_ packets should be
paced, such as pacing rates/account for audio/max queue length etc.

The RtpPacketSender interface exposed from the rtp_rtcp module handles
only the actual sending of packets.

Some minor cleanups are included here.

97b6c757bc New pacer: make FlexFEC and Video priority equal
Perf dashboard show a very minor change with the new pacer, for tests
that use flexfec. I have found that previously fec was in fact
prioritized at the same level as video, see eg PacketTypeToPriority()
in RTPSender.

With the new pacer we put fec in between video and padding.
Not sure if this is in fact an actual problem. In the non-loss case
the frame latency should actually be slighly lower, but on the other
hand if we have loss fec won't be applied until after the full frame
has been sent and so we may end up sending NACK before we apply the
FEC and recover a packet.

Just to avoid any problems let's revert to the old behavior.

c4f047d627 Make WebRTC-Pacer-LegacyPacketReferencing default off
This makes the code path where packets are directly owned by PacedSender
rather that being temporarily put in the RtpPacketHistory the default.

Functionally, this should essentially be a noop, with only minor timing
differences.

The old code-path will stay around for a short while and then be
removed once we are certain there are no regressions.

b88fd31384 New pacer: keepalive fix, unittests coverage
This CL fixes a bug affecting the new PacedSender code path (not yet
active): keepalive packets will always be sent, even if sending is
paused or network is congested.

Mainly though, it refactors all the PacedSender unittests and makes
sure all of them (as applicable) are run using both the old and the new
code paths.

add proper integration testing. Here, I mostly add coverage for the new
send methods. When the old code-path is removed, all tests need to be
converted to exclusively use the owned path.

665174fdbb Reformat the WebRTC code base
Running clang-format with chromium's style guide.

The goal is n-fold:
 * providing consistency and readability (that's what code guidelines are for)
 * preventing noise with presubmit checks and git cl format
 * building on the previous point: making it easier to automatically fix format issues
 * you name it

Please consider using git-hyper-blame to ignore this commit.

ce4829a04a Adds trial to ignore video pacing for audio packets.
This CL adds a field trial to ensure that audio packets are only blocked
if they are also accounted for. Without the field trial active, audio
packets are blocked due to full congestion windows and media budget
overuse caused by video packets, even it the audio is not accounted for.

c235a8d2bb Adds trial to always send padding packets when not sending video.
This can be used to avoid getting stuck in a state where the encoder
is paused due to low bandwidth estimate which means no additional
feedback is received to update the bandwidth estimate. This could
happen if feedback packets are lost.

682c6498a2 Removes timeout warnings from pacer before first packet.
The paced sender did not update the time out clock before the first
packet was send in paused state. This caused it to incorrectly log
warnings about elapsed time. This CL fixes this.

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.
