This queue is a more strict round robing queue, unlike the class
named RoundRobinPacketQueue. That is, we don't have the same logic to
prioritize lower-bitrate streams.
The queue time mechanism is essentially directly copied from the
previous implementation however.

This reverts commit 942cac2e9e6a205fd673dc003a051cfb3867f2e3.
Reason for revert: Reverting while downstream updates are made.
Original change's description:
> Make deletion of Connection objects more deterministic.
>
> This changes most deletion paths of Connection objects to go through
> the owner class of the Connection instances, Port.
>
> In situations where Connection objects still need to be deleted
> asynchronously, `async = true` can be passed to
> `Port::DestroyConnection` and get the same behavior as
> `Connection::Destroy` formerly gave.
>
> The `Destroy()` method still exists for downstream compatibility, but
> instead of deleting connection objects asynchronously, the deletion
> now happens synchronously via the Port class.

Prior to this CL, rollback did not restore FiredDirection and remote
streams were only sometimes restored. This resulted in not firing
ontrack if a track was rolled back and then added again on the same
transceiver.
Rollback also never performed OnTrack, which is incorrect because a
transceiver that goes from sendrecv to inactive will cause OnRemoveTrack
and if this is rolled back (so we become sendrecv again) then we need
OnTrack to fire.
This CL improves rollback's "memory", fires ontrack in Rollback() and
adds test coverage.
Needed to solve similar bugs in the Chromium layers as well:

Before this CL, fast retransmission didn't follow the SHOULDs:
https://datatracker.ietf.org/doc/html/rfc4960#section-7.2.4
* "the sender SHOULD ignore the value of cwnd (...)"
* "(...) and SHOULD NOT delay retransmission for this single
packet."
With this CL, chunks that are eligible for fast retransmission (limited
to what can fit in a single packet) will be sent just after having
received the SACK that reported them missing and transitioned the socket
into fast recovery, and they will be sent even if the congestion window
is full.

This CL makes OutstandingData keep track of chunks that are eligible for
fast retransmission. When the socket goes into fast recovery, the
reported missing chunks can be retransmitted quickly (ignoring the
congestion window) according to
https://datatracker.ietf.org/doc/html/rfc4960#section-7.2.4.
The CL also adds the new API to OutstandingData to retrieve only the
chunks that are eligible for fast retransmission, and moves the
remaining chunks to the ordinary list of chunks to be retransmitted
later.
This solves an issue where the retransmission timer wouldn't start if
there wouldn't be any chunks to fast-retransmit.
It doesn't, however, make sure that chunks that should be fast
retransmitted can send even when the congestion window is full. That
will be solved in the follow-up CL.

This calls out the fact that SetChannel() is only used on M-section activation; ClearChannel is called on deactivation, and we never change the channel while a transceiver is active.

Fixing a race condition where session.sampleRate changes before AudioDeviceIOS::HandleValidRouteChange() finishes.
session.sampleRate is read into session_sample_rate at 576 and used at 623 to initialize the audio unit. However, in the call to SetupAudioBuffersForActiveAudioSession() the session.sampleRate is read again and may have changed, resulting in different sample rates used for the buffers and the audio unit. The consequence is a sample rate mismatch with either high pitched or low pitched audio.
The fix is to always use the buffer sample rate for the audio unit.
The DCHECK at 622 would save us in debug, but not in production, hence removed.

With MSVC, compiling with AVX2 support will also result in the
generation of BMI2 instructions. Some early Haswell CPUs reportedly support AVX2 but not BMI2. We have seen crashes (illegal instruction)
on these CPUs in our AVX2 code paths on MULX instructions (part of BMI2).
Including a check for BMI2 when checking for AVX2 support is
expected to solve the issue.
Please see the bug referenced below for more background on this issue.
