a63bee55f2 Remove Mutex from BaseChannel.
There's a bit of copy/pasted code in the channel code, which is
making moving network traffic consistently over to the network thread
a bit trickier than it needs to be, so I'm also updating variable
names used in Set[Local|Remote]Content_w to be more explicitly the same
and make it clear that the code is copy/pasted (and future updates can
consolidate more of it).

Also removing some code from the video/voice media channels that's
effectively dead code (vector + registration methods that aren't needed)

eb9c3f237b Handle OnPacketSent on the network thread via MediaChannel.
* Adds a OnPacketSent callback to MediaChannel, which matches with
  MediaChannel::NetworkInterface::SendPacket.
* Moves the OnPacketSent handling to the media channel implementations
  (video/voice) and removes the PeerConnection/SdpOfferAnswerHandler
  layer from the call path.
* Call::OnSentPacket is called directly from the channels on the network
  thread. This eliminates a PostTask to the worker thread for every
  audio/video network packet.
* Remove sigslot dependency from MediaChannel (and derived).

15e078c574 Fix unsignalled ssrc race in WebRtcVideoChannel.
BaseChannel adds and removes receive streams on the worker thread
(UpdateRemoteStreams_w) and then posts a task to the network thread to
update the demuxer criteria. Until this happens, OnRtpPacket() keeps
forwarding "recently removed" ssrc packets to the WebRtcVideoChannel.
Furthermore WebRtcVideoChannel::OnPacketReceived() posts task from the
network thread to the worker thread, so even if the demuxer criteria was
instantly updated we would still have an issue of in-flight packets for
old ssrcs arriving late on the worker thread inside WebRtcVideoChannel.

The wrong ssrc could also arrive when the demuxer goes from forwarding
all packets to a single m= section to forwarding to different m=
sections. In this case we get packets with an ssrc for a recently
created m= section and the ssrc was never intended for our channel.

This is a problem because when WebRtcVideoChannel sees an unknown ssrc
it treats it as an unsignalled stream, creating and destroying default
streams which can be very expensive and introduce large delays when lots
of packets are queued up.

This CL addresses the issue with callbacks for when a demuxer criteria
update is pending and when it has completed. During this window of time,
WebRtcVideoChannel will drop packets for unknown ssrcs.

This approach fixes the race without introducing any new locks and
packets belonging to ssrcs that were not removed continue to be
forwarded even if a demuxer criteria update is pending. This should make
a=inactive for 50p receive streams a glitch-free experience.

f7b1b95f11 Add RTCRemoteOutboundRtpStreamStats for audio streams
Changes:
- adding the `RTCRemoteOutboundRtpStreamStats` dictionary (see [1])
- collection of remote outbound stats (only for audio streams)
- adding `remote_id` to the inbound stats and set with the ID of the
  corresponding remote outbound stats only if the latter are available
- unit tests

Tested: verified from chrome://webrtc-internals during an appr.tc call

ad3258647e Reland "Prepare to avoid hops to worker for network events."
This is a reland of d48a2b14e7545d0a0778df753e062075c044e2a1

The diff of the reland (what caused the tsan error) can be seen
by diffing patch sets 2 and 3. Essentially I missed keeping the calls
to the transport controller on the worker thread. Note to self to add
thread/sequence checks to that code so that we won't have to rely on
tsan :)

Reason for revert: TSan tests started to fail constantly after this CL (it looks like it is flaky and the CQ was lucky to get green). See https://ci.chromium.org/ui/p/webrtc/builders/ci/Linux%20Tsan%20v2/25042/overview.

This moves the thread hop for network events, from BaseChannel and
into Call. The reason for this is to move the control over those hops
(including DeliverPacket[Async]) into the same class where the state
is held that is affected by those hops. Once that's done, we can start
moving the relevant network state over to the network thread and
eventually remove the hops.

I'm also adding several TODOs for tracking future steps and give

33c0ab4948 Call MediaChannel::OnPacketReceived on the network thread.
Functionality wise, there should be no change with this CL, aside
from updating tests to anticipate OnPacketReceived to handle the packet
asynchronously (as already was the case via BaseChannel).

This only removes the network->worker hop out of the BaseChannel
class into the WebRTC MediaChannel implementations. However, it updates
the interface contract between BaseChannel and MediaChannel to align
with how we want things to work down the line, i.e. avoid hopping to
the worker thread for every rtp packet.

The following steps will be to update the video and voice channel
classes to call Call::DeliverPacket on the network thread and only
handle unsignalled SSRCs on the worker (exception case).

46ea5d7f82 Surface the number of encoded channels
Two audio channels going into the AudioSource::Sink can either be
down-mixed to mono or encoded as stereo. This change enables WebRTC
users (such as Chromium) to query the number of audio channels actually
encoded. That information can in turn be used to tailor the audio
processing to the number of channels actually encoded.

This change fixes webrtc:8133 from a WebRTC perspective and will be
followed up with the necessary Chromium changes.

ceb44959ca Reland: Wires up WebrtcKeyValueBasedConfig in media engines.
This is a reland of
https://webrtc-review.googlesource.com/c/src/+/174261

Patchset 1 contains the old cl (plus a merge conflict fix).
Later patchets are bufixes: A PeerConnection can be created without a
Call instance (in the case of DataChannel only), so we can't always
use that to fetch the current trials.

Old CL descritpion:

This replaces field_trial:: -based functions from system_wrappers.
Field trials are still used as fallback, but injectable trials are now
possible.

c6cf902034 Improves logging in MediaChannel
This CL changes the style of logging for an API which is essential when
WebRTC is used in Chrome. By changing the format, we can more easily
tie in (search for tags etc.) logs from WebRTC with logs in Chrome.
See e.g.
https://chromium-review.googlesource.com/c/chromium/src/+/2093443
for more details.

I decided to use a new private method to avoid using rtc::StringBuilder.
The idea was to make the log statements less complex and more condensed.

39adce1498 Add RtpEncodingParameters.adaptive_ptime.
When enabled:
- Creates an audio network adapter config that is passed to audio send
stream.
- Configures a lower default min bitrate.

All parameters can be configured via a field trial that can also force
enable the audio network adaptor (this is mainly intended for testing).

09e9a83d91 Change the way that AecDumps are created in APM
This CL changes the way that AecDumps are created in APM. Instead
of being injected, they are now created via the API.

This removes the AecDumpFactory from the API surface of APM and
makes the API more explicit.

The CL will be followed by one more CL that deprecates the usage
of the AttachAecDump API also within the audio_processing
and the fuzzer folders.

The CL also moves the aec_dump.* files from the include folder
to the aec_dump folder and changes the build files. The reasons
for this are that
1) The content of aec_dump.h is not really part of the API
   surface of APM.
2) Those files anyway needed to be moved to a separate build-
   target to avoid a circular build-file dependency caused by
   the other changes in this CL

0357b3e7b6 RtpTransceiverInterface: add header_extensions_to_offer()
This change adds exposure of a new transceiver method for getting
the total set of supported extensions stored as an attribute,
and their direction. If the direction is kStopped, the extension
is not signalled in Unified Plan SDP negotiation.

Note: SDP negotiation is not modified by this change.

Changes:
- RtpHeaderExtensionCapability gets a new RtpTransceiverDirection,
  indicating either kStopped (extension available but not signalled),
  or other (extension signalled).
- RtpTransceiver gets the new method as described above. The
  default value of the attribute comes from the voice and video
  engines as before.

3f1aee3cbb Change network_priority from a double to an enum.
It can only be one of four possible values, so it never made sense
for it to be a double. Other than the fact that its neighbor
bitrate_priority is a double, and they're both defined as the same enum
in the web spec. However, while bitrate_priority being a double
offers more flexibility than the web spec, network_priority being a
double is only confusing.
