f8187e0a82 [Unified Plan] Support multiple BUNDLE groups.
In this CL, JsepTransportController and MediaSessionDescriptionFactory
are updated not to assume that there only exists at most a single BUNDLE
group but a list of N groups. This makes it possible to create multiple
BUNDLE groups by having multiple "a=group:BUNDLE" lines in the SDP.

This makes it possible to have some m= sections in one group and some
other m= sections in another group. For example, you could group all
audio m= sections in one group and all video m= sections in another
group. This enables "send all audio tracks on one transport and all
video tracks on another transport" in Unified Plan. This is something
that was possible in Plan B because all ssrcs in the same m= section
were implicitly bundled together forming a group of audio m= section and
video m= section (even without use of the BUNDLE tag).

PeerConnection will never create multiple BUNDLE groups by default, but
upon setting SDP with multiple BUNDLE groups the PeerConnection will
accept them if configured to accept BUNDLE. This makes it possible to
accept an SFU's BUNDLE offer without having to SDP munge the answer.

C++ unit tests are added. This fix has also been verified manually on:
https://jsfiddle.net/henbos/to89L6ce/43/

Without fix: 0+2 get bundled, 1+3 don't get bundled.
With fix: 0+2 get bundled in first group, 1+3 get bundled in second
group.

8546666cb9 Add threading assertions to TransceiverList
Also add a function for accessing the list as internal transceivers
rather than accessing the proxy objects; this exposes where the
internal objects are accessed and where we need external references.

Used the new list function in sdp_offer_answer wherever possible.

Adds an UnsafeList function that is not thread guarded, so that the
job of rooting out those instances can be done in a later CL.

516e284351 Remove DataChannelType and deprecated option disable_sctp_data_channels
Since there is only a single type of DataChannel now, the enum was only used
when data channels were disabled at the PC API. That option has been
deprecated 4 years ago, it's now time to remove it.

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).

bfd9ba8802 Fix unsafe variable access in RTCStatsCollector
With this change, all production callers of BaseChannel::transport_name()
will be making the call from the right thread and we can safely delegate
the call to the transport itself. Some tests still need to be updated.
This facilitates the main goal of not needing synchronization inside
of the channel classes, being able to apply thread checks and eventually
remove thread hops from the channel classes.

A downside of this particular change is that a blocking call to the
network thread from the signaling thread inside of RTCStatsCollector
needs to be done. This is done once though and fixes a race.

This will allow PeerConnection to be able to expect the

8cb9706288 AddRemoteCandidate on the network thread
SdpOfferAnswerHandler now hands over most of the work of adding a
remote candidate over to PeerConnection where the work will be
carried out asynchronously on the network thread (was
synchronous/blocking).

Once added, reporting (ReportRemoteIceCandidateAdded) continues on the
signaling thread as before. The difference is though that we don't
block the UseCandidate() operation which is a part of applying the
local and remote descriptions.

Besides now being asynchronous, there's one behavioural change:
Before starting the 'add' operation, the validity of the candidate
instance to be added, is checked. Previously if such an error occurred,
the error was silently ignored.

6e4fcac313 Revert "Remove thread hops from events provided by JsepTransportController."
This reverts commit f554b3c577.

Reason for revert: Parent CL breaks FYI bots.
See https://webrtc-review.googlesource.com/c/src/+/206466

Original change's description:
> Remove thread hops from events provided by JsepTransportController.
>
> Events associated with Subscribe* methods in JTC had trampolines that
> would use an async invoker to fire the events on the signaling thread.
> This was being done for the purposes of PeerConnection but the concept
> of a signaling thread is otherwise not applicable to JTC and use of
> JTC from PC is inconsistent across threads (as has been flagged in
> webrtc:9987).
>
> This change makes all CallbackList members only accessible from the
> network thread and moves the signaling thread related work over to
> PeerConnection, which makes hops there more visible as well as making
> that class easier to refactor for thread efficiency.
>
> This CL removes the AsyncInvoker from JTC (webrtc:12339)
>
> The signaling_thread_ variable is also removed from JTC and more thread
> checks added to catch errors.

f554b3c577 Remove thread hops from events provided by JsepTransportController.
Events associated with Subscribe* methods in JTC had trampolines that
would use an async invoker to fire the events on the signaling thread.
This was being done for the purposes of PeerConnection but the concept
of a signaling thread is otherwise not applicable to JTC and use of
JTC from PC is inconsistent across threads (as has been flagged in
webrtc:9987).

This change makes all CallbackList members only accessible from the
network thread and moves the signaling thread related work over to
PeerConnection, which makes hops there more visible as well as making
that class easier to refactor for thread efficiency.

This CL removes the AsyncInvoker from JTC (webrtc:12339)

The signaling_thread_ variable is also removed from JTC and more thread
checks added to catch errors.

6cd4058504 Fix unsynchronized access to mid_to_transport_ in JsepTransportController
* Added several thread checks to JTC to help with programmer errors.
* Avoid a few Invokes() to the network thread here and there such
  as for fetching sctp transport name for getStats(). The transport
  name is now cached when it changes on the network thread.
* JsepTransportController instances now get deleted on the network
  thread rather than on the signaling thread + issuing an Invoke()
  in the dtor.
* Moved some thread hops from JTC over to PC which is where the problem
  exists and also (imho) makes it easier to see where hops happen in
  the PC code.
* The sctp transport is now started asynchronously when we push down the
  media description.
* PeerConnection proxy calls GetSctpTransport directly on the network
  thread instead of to the signaling thread + blocking on the network
  thread.
* The above changes simplified things for webrtc::SctpTransport which
  allowed for removing locking from that class and delete some code.
