9e334b7d99 Remove channel_manager.h from most .h files
This ensures that only the compilation units that actually need
ChannelManager details can see it.

25adc8e36b Eliminate channel.h from rtp_transmission_manager.cc
This also hides the existence of the classes VideoChannel and
VoiceChannel from anything that does not include "channel.h".

This better reflects the ownership passing of AddTrack, and is more

0d5ce62d01 Make RtpTransceiver not inherit from RefCountedObject.
Also update API proxy Create() factory functions to accept the inner
reference counted object via scoped_refptr instead of a raw pointer.
This is to avoid accidentally creating and deleting an object when
passing an inner object to a proxy class.

Consider something like:
  auto proxy = MyProxy::Create(
      signaling_thread(), make_ref_counted<Foo>());

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`

d3251968d1 Prepare to rename RTC_NOTREACHED to RTC_DCHECK_NOTREACHED
Add implementation of RTC_DCHECK_NOTREACHED equal to the RTC_NOTREACHED.
The new macros will replace the old one when old one's usage will be
removed. The idea of the renaming to provide a clear signal that this
is debug build only macros and will be stripped in the production build.

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.

c335b0e63b [Unified Plan] Don't end audio tracks when SSRC changes.
The RemoteAudioSource has an AudioDataProxy that acts as a sink, passing
along data from AudioRecvStreams to the RemoteAudioSource. If an SSRC is
changed (or other reconfiguration happens) with SDP, the recv stream and
proxy get recreated.

In Plan B, because remote tracks maps 1:1 with SSRCs, it made sense to
end remote track/audio source in response to this. In Plan B, a new
receiver, with a new track and a new proxy would be created for the new
SSRC.

In Unified Plan however, remote tracks correspond to m= sections. The
remote track should only end on port:0 (or RTCP BYE or timeout, etc),
not because the recv stream of an m= section is recreated. The code
already supports changing SSRC and this is working correctly, but
because ~AudioDataProxy() would end the source this would cause the
MediaStreamTrack of the receiver to end (even though the media engine
is still processing the remote audio stream correctly under the hood).

This issue only happened on audio tracks, and because of timing of
PostTasks the track would kEnd in Chromium *after* promise.then().

This CL fixes that issue by not ending the source when the proxy is
destroyed. Destroying a recv stream is a temporary action in Unified
Plan, unless stopped. Tests are added ensuring tracks are kLive.

I have manually verified that this CL fixes the issue and that both
audio and video is flowing through the entire pipeline:
