43a5dd86c2 Implement codec selection api
The implementation covers the latest specification, but does not
support mixed-codec simulcast at the moment.
Changing codec for audio and video is supported.

1f31c201cd Split fake media channel classes
This allows to remove some calls to CreateMediaChannel
in the RtpTransceiver code.

This removes the fake engines owning the channels and moves
the responsibility to the tests themselves as it's quite
hard to both return a unique_ptr to a channel and still own it.

The various channel getters from the fake engine are thus
also removed and tests updated accordingly, the channel is
retrieved from internal structs in the tests by going
through the RtpTransceiver objects as it's not possible to
safely get the channels from only a sender or receiver.

As some tests are running in both PlanB and Unified Plan,
getting a transceiver is not working for PlanB. As PlanB
has been deprecated and will eventually be removed,
the problematic tests have either been removed or updated
to only run with Unified Plan.

61bacd1ddd Enable WebRTC-SplitMediaChannel by default
This is a refactoring that should have no production impact.
It has been activated for 2 weeks before, but was rolled back
because of a performance impact - this has now been fixed.

2f55370634 Reland "Use two MediaChannels for 2 directions."
This reverts commit 18c869bc36b342cd4a79947067e52a93a04a7808.

Reason for revert: Added a field trial that allows landing the code without affecting performance in prod.

This CL also incorporates subsequent CLs that also had to be reverted.

36fafc8827 Split MediaChannel class to sender and receiver
This allows callers to differentiate on whether they need the
channel for sending or receiving purposes.

Note: This CL is incomplete, in that many places cast the pointers
to the concrete subclasses "VideoMediaChannel" and "AudioMediaChannel", which are not split into sending and receiving APIs.

The long term goal is to make two MediaChannel-like class APIs, with distinct implementations, and let the RtpSender and RtpReceiver manage those objects, rather than keeping them in the RtpTransceiver.

0a16276290 Restore FiredDirection and maybe fire OnTrack in Rollback.
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:

a8ad11de82 [Rollback] Don't end tracks when transceiver is still in use.
Prior to this CL, calling RtpTransceiver::SetChannel() with null
arguments would cause the receiver's track to end. This is wrong,
because the channel can be nulled for other reasons than the transceiver
being stopped/removed - such as when the transceiver is rolled back but
still in use. Also, stopping a transceiver will end the track, so we
should simply ensure to always stop the transceiver when that is needed.

This CL makes sure that the transceiver is stopped or stopping in all
appropriate places, allowing us to remove the ability to end the source
for any other reason. A side-effect of this is that:
- The track never ends prematurely, fixing https://crbug.com/1315611.
- Removed transceivers are always stopped, fixing
  https://crbug.com/webrtc/14005.

This CL fixes the issue of track being ended in the ontrack event when
running https://jsfiddle.net/henbos/nxebusjm/.
- We don't have WPT test coverage for this, so I'll add that separately.

With SetSourceEnded() removed, some stopping/stop in response to
rejecting locally SDP munged content had to be added in order not to
regress the existing test coverage for this:
*PeerConnectionInterfaceTest.RejectMediaContent/1

6589def397 Align sender/receiver teardown in RtpTransceiver.
This makes SetChannel() consistently make 2 invokes instead of a
multiple of senders+receivers (previous minimum was 4 but could be
larger).

* Stop() doesn't hop to the worker thread.
* SetMediaChannel(), an already-required step on the worker thread for
  senders and *sometimes* for receivers[1], is now consistently required
  for both. This simplifies transceiver teardown and enables the next
  bullet.
* Transceiver stops all senders and receivers in one go rather than
  ping ponging between threads.

[1] When not required, it was done implicitly inside of Stop().
  See changes in `RtpTransceiver::SetChannel`

5411b174c8 Add a channel factory interface.
The interface is implemented by the ChannelManager and contains methods
to create and destroy media channel objects as used by a transceiver.

This will subsequently allow us to delete the channel objects from
the transceiver class where ownership really lies rather than from
the outside - which is currently required by some tests that keep
channel objects on the stack. We'll furthermore be able to do the
destruction asynchronously without additional Invoke()s as we do now
which will remove an Invoke when making sdp changes.

With introducing the interface, the following simplifications were made:
* ChannelManager constructed on the signaling thread.
  Before, there was an Invoke in the context class, which existed
  for the purposes of calling MediaEngine::Init() (which in turn is
  only needed for the VoiceEngine). This Invoke has now been moved
  into the CM (more tbd).
* The CM now has a pointer to the signaling thread (since that's the
  construction thread). That allows us to remove the signaling thread
  parameter from the CreateFooChannel methods.
* The ssrc_generator (UniqueRandomIdGenerator) instance for SSRCs moved
  from SdpOfferAnswerHandler to the CM, as it's always used in
  combination with the CM. This simplifies the CreateFooChannel methods
  as well as a couple of other classes that have a CM dependency.
* Removed DestroyFooChannel related code from SdpOfferAnswerHandler since
  the channel type detail can be taken care of by the CM.

4f8a58c3d2 Remove 2 Invokes to the network thread when creating a channel.
...and one when destroying a channel object.

This CL removes Init_n() and Deinit_n() from the BaseChannel class.
Channel classes now use SetRtpTransport to do initialization and
uninitialization on the network thread.

Notably if an implementation has called SetRtpTransport() with a valid
transport pointer, it is required that SetRtpTransport be called again
with a nullptr before the channel object can be deleted.

In situations where multiple channels are created, this can mean
a substantial reduction in thread hops. We still hop to the worker
in order to construct the objects - this can probably be avoided
and SetChannel() is still a synchronous operation for the transceivers.
Furthermore, teardown of channel objects also still happens
synchronously and across network/worker/signaling threads.

4ccdf932e1 VideoRtpReceiver & AudioRtpReceiver threading fixes.
For implementations where the signaling and worker threads are not
the same thread, this significantly cuts down on Thread::Invoke()s that
would block the signaling thread while waiting for the worker thread.

For Audio and Video Rtp receivers, the following methods now do not
block the signaling thread:
* GetParameters
* SetJitterBufferMinimumDelay
* GetSources
* SetFrameDecryptor / GetFrameDecryptor
* SetDepacketizerToDecoderFrameTransformer

Importantly this change also makes the track() accessor accessible
directly from the application thread (bypassing the proxy) since
for receiver objects, the track object is const.

Other changes:

* Remove RefCountedObject inheritance, use make_ref_counted instead.
* Every member variable in the rtp receiver classes is now RTC_GUARDED
* Stop() now fully clears up worker thread state, and Stop() is
  consistently called before destruction. This means that there's one
  thread hop instead of at least 4 before (sometimes more), per receiver.
* OnChanged triggered volume for audio tracks is done asynchronously.
* Deleted most of the JitterBufferDelay implementation. Turns out that
  it was largely unnecessary overhead and complexity.

It seems that these two classes are copy/pasted to a large extent
so further refactoring would be good in the future, as to not have to
fix each issue twice.

cc7a36818f Move header negotiation state to transceivers.
The channel classes have stored the negotiated headers but a more
natural place to store them is in the RtpTransceiver class where
RtpHeaderExtension state is managed as well as the implementation of
the only method that depends on the stored state,
HeaderExtensionsNegotiated().

Also adding a TODO for further improvements where we're unnecessarily
storing state in the channel classes for the purposes of the transports.

99c8a80b8e Change the first-packet-received notification in Channel.
This changes the notification to a single std::function pointer
instead of being a sigslot::signal1<> collection.

Summary:

* Remove SignalFirstPacketReceived_, the last sigslot member variable.
  (still inherits from sigslot::has_slots<>)
* BaseChannel doesn't post to the signaling thread anymore. The only
  reason that remains for the signaling_thread_ variable, is for
  thread checking.
* Remove BaseChannel's reliance on MessageHandlerAutoCleanup
  (still inherits from MessageHandler)

RtpTransceiver is the consumer of this event. That class is also the
class that sits between the PC classes and the channel object, holding
a pointer to the channel and managing calls that come in on the
signaling thread, such as SetChannel. The responsibility of delivering
the first packet received on the signaling thread is now with
RtpTransceiver:

* RtpTransceiver always requires a ChannelManager instance. Previously
  this variable was sometimes set, but it's now required.
* Updated tests in rtp_transceiver_unittest.cc to include a
  ChannelManager as well as fix them to include call expectations for
  mock sender and receivers.

fe041643b4 Add utility to count the number of blocking thread invokes.
This is useful to understand how often we block in certain parts of the
api and track improvements/regressions.

There are two macros, both are only active for RTC_DCHECK_IS_ON builds:

* RTC_LOG_THREAD_BLOCK_COUNT()
Example:
  void MyClass::MyFunction() {
    RTC_LOG_THREAD_BLOCK_COUNT();
    thread_->Invoke<void>([this](){ DoStuff(); });
  }

When executing this function during a test, the output could be:

  (my_file.cc:2): Blocking MyFunction: total=1 (actual=1, would=0)

The words 'actual' and 'would' reflect whether an actual thread switch
was made, or if in the case of a test using the same thread for more
than one role (e.g. signaling, worker, network are all the same thread)
that an actual thread switch did not occur but it would have occurred
in the case of having dedicated threads. The 'total' count is the sum.

* RTC_DCHECK_BLOCK_COUNT_NO_MORE_THAN(x)
Example:
  void MyClass::MyFunction() {
    RTC_LOG_THREAD_BLOCK_COUNT();
    thread_->Invoke<void>([this](){ DoStuff(); });
    thread_->Invoke<void>([this](){ MoreStuff(); });
    RTC_DCHECK_BLOCK_COUNT_NO_MORE_THAN(1);
  }

When a function is known to have blocking calls and we want to not
regress from the currently known number of blocking calls, we can use
this macro to state that at a certain point in a function, below
where RTC_LOG_THREAD_BLOCK_COUNT() is called, there must have occurred
no more than |x| (total) blocking calls. If more occur, a DCHECK will
hit and print out what the actual number of calls was:

# Fatal error in: my_file.cc, line 5
# last system error: 60
# Check failed: blocked_call_count_printer.GetTotalBlockedCallCount() <= 1 (2 vs. 1)
