This is to allow testing without using the singleton sctp library.
cricket::SctpTransportInternalFactory is renamed to webrtc::SctpTransportFactoryInterface and moved to the API folder to follow the API structure.
Tests can use test/pc/sctp/fake_sctp_transport.h to inject a faked data channel implementation.

3a034e15b4 Split DataChannel into two separate classes for RTP and SCTP.
Done in preparation for some threading changes that would be quite
messy if implemented with the class as-is.

This results in some code duplication, but is preferable to
one class having two completely different modes of operation.

RTP data channels are in the process of being removed anyway,
so the duplicated code won't last forever.

4c1e7cc19b [Adaptation] Add ability to inject resources on the PeerConnection.
This unblocks injecting platform-specific resources, such as power
usage signals in Chrome.

This CL adds AddAdaptationResource to PeerConnectionInterface and
integration tests verifying that if an injected resource is overusing,
resolution will soon be reduced.

To aid testing, some testing-only classes have been updated.

ProcessFrameP: locks crit_
ReceiveFrameP: locks crit_callback_
-------------
SendFrameP: locks crit_callback_
MicrophoneVolume: locks crit_

Lock crit_callback_ was rolled in under crit_ instead.

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.

44d7ec0683 Add Opus-only audio codec factories
Many WebRTC users need only Opus, and no other audio codecs. This
makes it convenient for them to do the right thing.

To prove that the new factories work, use them in
PeerConnectionEndToEndTest.

a3728d310d Reland "[PeerConnection] Use an OperationsChain in PeerConnection for async ops."
This is a reland of 1dddaa1a84330091ca083c950ef2e24a85a48fc8

The regression that caused the original CL to be reverted was the fact that
invoking SetLocalDescription() inside of the CreateOffer() callback was no
longer executing synchronously and immediately.

In this CL, the original CL is patched so that the CreateOffer() operation
is marked as completed just before invoking the CreateOffer() callback
(versus doing it just afterwards). This ensures that the OperationsChain is
popped before the callback runs. The same applies for CreateAnswer().

See diff between Patch Set 1 (Original CL) and the latest Patch Set.

1dddaa1a84 [PeerConnection] Use an OperationsChain in PeerConnection for async ops.
For background, motivation, requirements and implementation notes, see
https://docs.google.com/document/d/1XLwNN2kUIGGTwz9LQ0NwJNkcybi9oKnynUEZB1jGA14/edit?usp=sharing

Using the OperationsChain will unblock future CLs from chaining multiple
operations together such as implementing parameterless
setLocalDescription().

In this CL, the OperationsChain is used in existing signaling operations
with little intended side-effects. An operation that is chained onto an
empty OperationsChain will for instance execute immediately, and
SetLocalDescription() and SetRemoteDescription() are implemented as
"synchronous operations".

The lifetime of the PeerConnection is not indended to change as a result
of this CL: All chained operations use a raw pointer to the PC that is
ensured not to be used-after-free using an "IsAlive" object.

There is one notable change though: CreateOffer() and CreateAnswer() will
asynchronously delay other signaling methods from executing until they
have completed.

Drive-by fix: This CL also ensures that early failing
CreateOffer/CreateAnswer operation's observers are invoked if the
PeerConnection is destroyed while a PostCreateSessionDescriptionFailure
is pending.

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

487f9a17e4 Reland "Refactor SCTP data channels to use DataChannelTransportInterface."
Also clears SctpTransport before deleting JsepTransport.

SctpTransport is ref-counted, but the underlying transport is deleted when
JsepTransport clears the rtp_dtls_transport.  This results in crashes when
usrsctp attempts to send outgoing packets through a dangling pointer to the
underlying transport.

Clearing SctpTransport before DtlsTransport removes the pointer to the
underlying transport before it becomes invalid.

This fixes a crash in chromium's web platform tests (see
https://chromium-review.googlesource.com/c/chromium/src/+/1776711).

api/transport/rtp/rtp_source.h.

8b14b0dea6 Revert "Refactor SCTP data channels to use DataChannelTransportInterface."
This reverts commit 4c85828ab272d9bd58789bad7b135b6287395f97.

Reason for revert:
Speculatively reverting this because it makes several web platform tests relating to RTCDataChannel flaky, see first failing roll:
https://chromium-review.googlesource.com/c/chromium/src/+/1776711

4c85828ab2 Refactor SCTP data channels to use DataChannelTransportInterface.
This change moves SctpTransport to be owned by JsepTransport, which now
holds a DataChannelTransport implementation for SCTP when it is used for
data channels.

This simplifies negotiation and fallback to SCTP.  Negotiation can now
use a composite DataChannelTransport, just as negotiation for RTP uses a
composite RTP transport.

PeerConnection also has one fewer way it needs to manage data channels.
It now handles SCTP and datagram- or media-transport-based data channels
the same way.

There are a few leaky abstractions left.  For example, PeerConnection
calls Start() on the SctpTransport at a particular point in negotiation,
but does not need to call this for other transports.  Similarly, PC
exposes an interface to the SCTP transport directly to the user; there
is no equivalent for other transports.
