eb48799ec5 Prepares PacingController for scheduled send tasks.
This CL is in preparation for a dynamic (possible TaskQueue-driven)
pacer that instead of processing blindly every 5ms, posts delayed
tasks to be executed when it is actually time to send packs.

This means we need the pacing controller to be able to figure out when
those execution times shall be, and be able to correctly update budget
levels as IntervalBudget only works correctly with periodic processing.

22fd5d7455 Fixes incorrect probe timing check.
In a recent CL, a line that puts a lower bound of 0 on time to next
probe was omitted:
https://webrtc-review.googlesource.com/c/src/+/158841/7/modules/pacing/bitrate_prober.cc#b143
That cause a misinterpretation in
https://webrtc-review.googlesource.com/c/src/+/158841/7/modules/pacing/pacing_controller.cc#290
which may lead to probes aborting if the module processing thread
sleeps a little too long.

739a5b3692 Refactors BitrateProber with unit types and absolute probe time.
Using unit types improves readability and some conversion in PacedSender
can be removed.

TimeUntilNextProbe() is replaced by NextProbeTime(), so returning an
absolute time rather than a delta. This fits better with the upcoming
TaskQueue based pacer, and is also what is already stored internally
in BitrateProber.

86d053c2db Use source_sets in component builds and static_library in release builds.
Static libraries don't guarantee that an exported symbol gets linked
into a shared library (and in order to support Chromium's component
build mode, WebRTC needs to be linked as a shared library).

Source sets always pass all the object files to the linker.

On the flip side, source_sets link more object files in release builds
and to avoid this, this CL introduces a the GN template "rtc_library" that
expands to static_library during release builds and to source_set during
component builds.

See: https://gn.googlesource.com/gn/+/master/docs/reference.md#func_source_set

5f01bf6c8b Refactor handling of TransportSequenceNumber in PacketRouter
The use of SetTransportWideSequenceNumber() and AllocateSequenceNumber()
is gone from webrtc, but some downstream code still references them.

This means we can do some simplifications.

The member that stores the sequence number is now always accessed while
holding the modules lock, so we can just use that and don't need to add
atomic operations on top.

SetTransportWideSequenceNumber() is only used to set the start sequence
number, it would be nice to set that in the constructor instead.

AllocateSequnceNumber() is now actually only used as a getter, so this
can be replace by a proper const getter method instead.

55dd72c54b Remove lock for process thread pointer from PacedSender.
Also adding code in preparation of hiding the Module
implementation in PacedSender. The implementation details of
how the PacedSender+ProcessThread interaction works, has now
been moved into PacedSender (and out of RtpTransportControllerSend).

Instead of adding a "GetModuleImplementationForTesting" method
to the PacedSender class (which would have been the lazy way
out), I incorporated MockedProcessThread in the PacedSender tests.
This means more boilerplate code but the Module functionality
can be tested separately from the PacedSender and down the line
I think it would be a good idea to start using a separate thread
in the test, which is how the class under test is really used
in production.

f5815fa6bb Remove WebRTC-Pacer-LegacyPacketReferencing flag and most usage
This flag has been default-off since Jul 24th (m77 branch) and apart
from a bug fixed on Aug 5th, there have been no reports of issues, so
let's remove it and start cleaning away the old code path.

Most of the usage within RtpSender/PacingController and their
respective unit tests are removed with this CL, but there will be
several more to follow.

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.

Mainly though, it refactors all the PacedSender unittests and makes

478cb46435 Add GeneratePadding method to replace TimeToSendPadding
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.
