831ae4ef65 Reland "[Perfect Negotiation] Implement non-racy version of SetLocalDescription."
This is a reland of d4089cae47
with the following fix:

Invoke MaybeStartGathering as the last step of DoSetLocalDescription.
This ensures that candidates and onicegatheringstatechange does not
happen before SLD is resolved. This is important for passing
external/wpt/webrtc/RTCPeerConnection-iceGatheringState.html.

4c9c75a2a6 Revert "[Perfect Negotiation] Implement non-racy version of SetLocalDescription."
This reverts commit d4089cae47.

Reason for revert: Breaks chromium WPT that is timing sensitive to onicegatheringstatechanges.
This CL accidentally moved the MaybeStartGatheringIceCandidates to after completing the SLD call. The fix is to move it back. I'll do that in a re-land.

d4089cae47 [Perfect Negotiation] Implement non-racy version of SetLocalDescription.
BACKGROUND

When SLD is invoked with SetSessionDescriptionObserver, the observer is
called by posting a message back to the execution thread, delaying the
call. This delay is "artificial" - it's not necessary; the operation is
already complete. It's a post from the signaling thread to the signaling
thread. The rationale for the post was to avoid the observer making
recursive calls back into the PeerConnection. The problem with this is
that by the time the observer is called, the PeerConnection could
already have executed other operations and modified its states.

This causes the referenced bug: one can have a race where SLD is
resolved "too late" (after a pending SRD is executed) and the signaling
state observed when SLD resolves doesn't make sense.

When implementing Unified Plan, we fixed similar issues for SRD by
adding a version that takes SetRemoteDescriptionObserverInterface as
argument instead of SetSessionDescriptionObserver. The new version did
not have the delay. The old version had to be kept around not to break
downstream projects that had dependencies both on he delay and on
allowing the PC to be destroyed midst-operation without informing its
observers.

THIS CL

This does the old SRD fix for SLD as well: A new observer interface is
added, SetLocalDescriptionObserverInterface, and
PeerConnection::SetLocalDescription() is overloaded. If you call it with
the old observer, you get the delay, but if you call it with the new
observer, you don't get a delay.

- SetLocalDescriptionObserverInterface is added.
- SetLocalDescription is overloaded.
- The adapter for SetSessionDescriptionObserver that causes the delay
  previously only used for SRD is updated to handle both SLD and SRD.
- FakeSetLocalDescriptionObserver is added and
  MockSetRemoteDescriptionObserver is renamed "Fake...".

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.

2e94de596e Add GetSctpStats to PeerConnectionInternal, remove sctp_data_channels()
This removes code from DataChannelController that exposes
an internal vector of data channels and puts the onus of
returning stats for a data channel, on the data channel
object itself. This will come in handy as we make threading
changes to the data channel object.

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.

The PacketSocketFactory dependency (if present on the object passed to
CreatePeerConnection(...)) is given as a raw pointer to the
PortAllocator, but the unique_ptr remains in the dependencies object
which is destroyed at the end of the Initialize call.

I could find no reason for the extra complexity of doing messaging

It also simplifies the peerconnection/datachannelcontroller coupling.

currently pending, such as CreateOffer() or CreateAnswer(),
AddIceCandidate() will not happen until the previous operation
completes.

a3728d310d Reland "[PeerConnection] Use an OperationsChain in PeerConnection for async ops."
This is a reland of 1dddaa1a84

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.

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.

7da4e563b7 Allow receive-only use of datagram transport for data channels.
Adds a field trial and configuration parameter to control whether
datagram transport may be used for data channels in a receive-only
manner.  By default, if use_datagram_transport_for_data_channels is
enabled, PeerConnection will create a datagram transport and offer its
use for outgoing calls as well as accept incoming offers with compatible
datagram transport parameters.

With this change, a receive_only mode is added for datagram transport
data channels.  When receive_only is set, the PeerConnection will not
create or offer datagram transports for outgoing calls, but will accept
incoming calls that offer compatible datagram transport parameters.

1b83a9e400 Only handle each RTCP once.
Previously, each RTCP packet was handled several times in a row, once
per m-section. This caused various weirdness and log warning spam, in
particular when using unified plan.

The cause was that the packets were wired trough each BaseChannel
instance up to the Call class. With this fix, the RTCP packets are wired
once per RtpTransportInternal via the common peer connection class.

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).

8b14b0dea6 Revert "Refactor SCTP data channels to use DataChannelTransportInterface."
This reverts commit 4c85828ab2.

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.

b689af4c99 Changes to enable use of DatagramTransport as a data channel transport.
PeerConnection now has a new setting in RTCConfiguration to enable use of
datagram transport for data channels.  There is also a corresponding field
trial, which has both a kill-switch and a way to change the default value.

PeerConnection's interaction with MediaTransport for data channels has been
refactored to work with DataChannelTransportInterface instead.

Adds a DataChannelState and OnStateChanged() to the DataChannelSink
callbacks.  This allows PeerConnection to listen to the data channel's
state directly, instead of indirectly by monitoring media transport
state.  This is necessary to enable use of non-media-transport (eg.
datagram transport) data channel transports.

For now, PeerConnection watches the state through MediaTransport as well.
This will persist until MediaTransport implements the new callback.

Datagram transport use is negotiated.  As such, an offer that requests to use
datagram transport for data channels may be rejected by the answerer.  If the
offer includes DTLS, the data channels will be negotiated as SCTP/DTLS data
channels with an extra x-opaque parameter for datagram transport.  If the
opaque parameter is rejected (by an answerer without datagram support), the
offerer may fall back to SCTP.

If DTLS is not enabled, there is no viable fallback.  In this case, the data
channels are negotiated as media transport data channels.  If the receiver does
not understand the x-opaque line, it will reject these data channels, and the
offerer's data channels will be closed.

1ba5dec769 Reland "Set the usage pattern bits for adding remote ICE candidates from SDP."
This is a reland of 7c6f74ab03

Compared to the previous commit, new bits are added to log calls of
AddIceCandidate, and the gathering and reception of IPv6 candidates.

Original change's description:
> Set the usage pattern bits for adding remote ICE candidates from SDP.
>
> Currently these bits are only set when a remote ICE candidate is
> successfully added via addIceCandidate. For non-trickled sessions in
> which the remote candidates are added via the remote description, these
> bits are lost. This also happens for trickled sessions, though a rare
> case, when addIceCandidate does not succeed because the peer connection
> is not ready to add any remote candidate.

79b6980020 [PeerConnection] Implement restartIce().
This is part of "Perfect Negotiation" (https://crbug.com/980872).
Spec PR here (merged): https://github.com/w3c/webrtc-pc/pull/2169
Spec: https://w3c.github.io/webrtc-pc/#dfn-localufragstoreplace

The restartIce() makes the next createOffer() generate new ICE
credentials, as if {iceRestart:true} was passed in as options. It also
causes negotiationneeded. This is better than manually restarting ICE
because it survives rollbacks (when that is implemented) and
restartIce() can be called regardless of current signalingState.
