The post-pacing part of the RTP sender has been moved from RTPSender
into the new RtpSenderEgress class. However, that class is not directly
used and instead a subset of method calls are passed through RTPSender.
This CL prepares for removing dependencies between RTPSender and
RtpSenderEgress. All current behavior is preserved, and unit tests are
unchanged to verify this.
For more context, see patch set 2.

Also changing to always register and unregister extensions by URI to

Previously the kDontRetransmit value was used to indicate packets that
should not be retransmitted but were put in the RtpPacketHistory anyway
as a temporary storage while waiting for a callback from PacedSender.
Since PacedSender now always owns the delayed packets directly, we can
remove all usage of StorageTye in RtpPacketHistory, and only put
packets there after pacing if RtpPacketToSend::allow_retransmission()
returns true.

These RTP header extensions are used for Unified Plan SDP / BUNDLE and
replace SSRC signaling.
Previously, the RTPSender would attach these header extensions to every
packet when configured. Now, the header extensions will be attached to
every packet until the an RTCP RR is received on that SSRC which
indicates the receiver knows what MID/RID the SSRC is associated with.
This should reduce overhead by 2-4 bytes per packet when the MID header
extension is used and by 4-8 bytes when both header extensions are used.

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.

If the SSRC of an RTP module is changed at runtime, we may get conflicts
with packets already there. Eg:
* Put seq# 123 in the history for SSRC 1.
* Change the SSRC to 2.
* Send a NACK for seq# 123 from SSRC 2.
Currently, we will respond with the packet belonging to SSRC 1 (and not
if the NACK specifies SSRC 1, to boot).
We can gen similar issues if the sequence number is changed, where
half frame are left in the buffer.
In these cases, the stream is likely being reset so we should just
clear the packet history too.

This CL fixes two issues related to the TransmissionOffset header
extension and the new (not yet active) pacer mode.
Previously capture time (if unset) would be populated when put into the
packet history before entering the pacer. Since the pacer now owns the
packets, this does not occur until packet is actually sent, if at all.
Capture has really nothing to do with the packet history, this should
be set by the RtpSender pre-pacing instead.
Furthermore, for retransmissions the old path would take the capture
time from the original packet, build the RTX-wrapped retransmission and
set the toffset extension of the RTX packet using that captured capture
time. Since RTX packets are now fully built before the pacer, this does
not work, and we need to transfer the capture time from the original to
the RTX packet instead.

The legacy code-path uses a hashmap as cache in order to speed up
finding the right rtp module to send on. The new path should use that
as well.
In addition, there are checks that verify if an RTP module can send
padding, in some cases payload based. These result in a number of
calls to methods in RTPSender requiring its lock to be taken. This CL
introduces a combined SupportsPadding() check method which performs
all those checks in one go.

This CL makes the new code path for paced sending functionally complete.
By default, the field trial WebRTC-Pacer-ReferencePackets is Enabled,
meaning that there is no behavior change unless the field trial is
forced to Disabled. This is done in tests, and can be done on the
command line for manual testing.

This change adds the writing and parsing of the `abs-capture-time` RTP header extension defined at:
http://www.webrtc.org/experiments/rtp-hdrext/abs-capture-time
We are still missing the code to:
- Negotiate the header extension.
- Collect capture time for audio and video and have the info sent with the header extension.
- Receive the header extension and use its info.

Unlike TimeToSendPadding(), the new GeneratePadding() method will
generate RTP packets and put them in the pacer queue, which will be
responsible for actually sending them.
A slight difference from previous logic is that we do not use a lower
bound of 50bytes for getting payload packets, instead we always try and
then abort if the next padding packet is larger than the current
available budget.
Since we're not sending the packets immediately, we don't need to worry
about twcc sequence numbering or updating the stats, that will be
handled by the general SendPacket() codepath. We can also omit the
PacingInfo struct and the return value of bytes sent, as that will
be handled when taking the packets out of the queue.

This CL also improves test coverage and fixes an issue where the
(until now) unused code path for useful padding did not respect the

This method will be called when PacedSender is using the new code path
that directly owns the packets to be sent.
It can be seen as combining a few features of the old code path:
* It checks if this is the correct RTP module and then sends, without
the need for PacketRouter to poll multiple methods for SSRC etc first.
* It partly corresponds to TimeToSendPacket(), but RTX encapsulation
now happens pre-pacer and FEC does not need to have a packet history,
so most of that method is not used.
* It implements most of PrepareAndSendPacket(), such as updating header
extensions, reporting stats and of course forwards to Transport. It
now also handles the history a bit differently, since media packets
will only be stored for potential retransmission post-pacer.

Currently, the packet in the history that most closely matches the bit
budget between two PacedSender::Process() calls is selected to be
retransmitted. This usually means that the smallest packet in the
history is selected over and over.
With this new field trial, we ignore the size constraint (since you're
sending padding, you obviously have some bandwidth to spare) and
instead prefer packets that have the fewest transmission times first,
and after that we prefer new packets over older ones. This way, in
case of available bandwidth but small loss, these padding packets have
a greater chance of actually being useful to the receiver.

This is a standardized metric. Spec:
https://w3c.github.io/webrtc-stats/#dom-rtcoutboundrtpstreamstats-totalpacketsenddelay
It is meant to replace the legacy googBucketDelay. The average
packet delay over any interval can be calculated as the delta
totalPacketSendDelay divided by the delta packetsSent between two
calls to getStats().
