ed10bd9549 Modify SetLocalDescription helpers to work with RtpTransceivers
This change allows EnableBundle and PushdownMediaDescription to
work with RtpTransceivers, which means they can be reused in the
Unified Plan version of SetLocalDescription.

6d6a2ae174 Refactor PeerConnection::UpdateSessionState
This rewrites UpdateSessionState to better show the logic common
to all description types and the logic specific to
offers/answers/etc. Separating these will allow more code to be
reused with the Unified Plan implementation.

2039306d66 Replace PeerConnection::Action with cricket::ContentAction
PeerConnection had an Action enum as a holdover from the
WebRtcSession merge with the same members as
cricket::ContentAction. Since ContentAction is used in more places
outside of PeerConnection, this change removes the Action enum and
replaces its use with cricket::ContentAction.

8a006916ce Use RTCError for internal PeerConnection methods
Calls to SetLocalDescription and SetRemoteDescription in
PeerConnection delegate to many different internal helper methods
which can fail. The error ultimately needs to propagate to the
caller and cause the SetXXXDescription to fail. Right now these
methods signal errors by returning false and copying the error
message into an out parameter. This changes these methods to
return RTCError instead and avoid the use of the out parameter.

2dfc42d7b6 Prepare to make BaseChannel depend on RtpTransportInternal only.
Eventually we want BaseChannel to depend on the RtpTransportInternal
instead of DtlsTransportInternal and share RtpTransport when bundling.
This CL is the first step.

Add SetRtpTransport and Init_w(RtptransportInternal*) to BaseChannel.
These two methods would replace the existing SetTransports and Init_w
methods.

Add new CreateVoice/VideoChannel methods to the ChannelManager which
 take RtpTransportInternal instead of Dtls/PacketTransportInternal.

|cotnent_name| is removed from the SrtpTransport to simplify to code
since it is only used for debugging.

InitNetwork_n is removed from BaseChannel in CL as well.

e169272507 Fixed a bug in determining ICE roles.
When the initial offer side uses the ICE lite implementation, and
initiates a peer connection with an endpoint with the full
implementation, the offer side assumes the controlled ICE role per
RFC5245 and the remote endpoint MUST take the controlling role.

This logic was partially implemented in SetRemoteTransportDescription in
reflection where the endpoint switches its role to the controlling after
receiving the offer. The bug was caused by the following
SetLocalDescription at the remote endpoint after creating the answer,
which overrides the role to the controlled since it has no initial offer
and the role is not reflected in SetLocalTransportDescription. This
results in no nomination of candidate pairs and timeout of establishing
the peer connection.

The fix adds reflection on one's ICE role in SetLocalTransportDescription.
This fix also takes into account the case when both sides use the lite
implementation of ICE and the initial offer side MUST take the controlling
role per RFC5245 in this case, which is the default behavior in the
current implementation.

eda6ccd0c2 Refactor BaseChannel creation in PeerConnection
This changes the CreateVoiceChannel/CreateVideoChannel helper
methods in PeerConnection to return the created channel instead of
setting it directly. That allows the Unified Plan version of
SetLocalDescription to use the same factory methods without the
assumption that there is at most one voice and one video channel.

Also simplifies and deduplicates the logic for determining the
transport name for a given channel in the presence of BUNDLE.

The DtlsSrtpTransport takes the reponsiblity of setting up DTLS-SRTP from
the BaseChannel.

The BaseChannel doesn't handle the signals from the P2P layer transport anymore.
The RtpTransport handles the signals from the PacketTransportInternal and the
DtlsSrtpTransport handles the DTLS-specific signals and determines when to extract
the keys and setting the parameters.

In channel_unittests.cc, call from DTLS to SDES is expected to fail since the
fallback from DTLS to SDES is not supported.

This deprecates the use of |direction()| and |set_direction()|

the signiture will change to return/set RtpTransceiverDirection.
Then external users can move back to these methods with the new

56d460902e Use the new AudioProcessing statistics everywhere.
The new interface uses optionals instead of default values, and only values that are actually used are included. To make it easy to add/remove stats in the future, the struct itself is copied around on all layers, instead of copying the values one by one. This CL also fixes a bug which caused several APM statistics to get stuck at a fixed level when there are no more receive streams (after some period where there were receive streams). Since APM doesn't know this happens, an argument was added to the GetStats call to pass this information down to APM.

316386747a Reland "SetRemoteDescriptionObserverInterface added."
Description for changes from the original CL:

Calling legacy SRD, implemented using
SetRemoteDescriptionObserverAdapter wrapping the old observer, was
meant to have the exact same behavior as the legacy SRD implementation
which invokes the callbacks in a Post.

However, in the CL that landed and got reverted (PS1), the Adapter had
its own message handler, and callbacks would be invoked even if the PC
was destroyed.

In PS2 I've changed the Adapter to use the PeerConnection's message
handler. If the PC is destroyed, the callback will not be invoked.
This gives identical behavior to before this CL, and the legacy
behavior is covered by a new unittest.

I changed the adapter to be an implementation detail of
peerconnection.cc, therefor some stuff was moved, and the only tests
covering this is now in peerconnection_rtp_unittest.cc.

This is a reland of 6c7ec32bd63ab2b45d4d83ae1de817ee946b4d72

a4ecf5571e Revert "SetRemoteDescriptionObserverInterface added."
This reverts commit 6c7ec32bd63ab2b45d4d83ae1de817ee946b4d72.

Reason for revert: Third party project breaks due to use-after-free
in the callback. I suspect this is because the adapter is processing
the async callback instead of the pc, i.e. callback is called from
SetRemoteDescriptionObserverAdapter::OnMessage instead of from
PeerConnection::OnMessage. This makes it possible for the callback to
be invoked after the PC is destroyed.

I argue this is how it should be done, and that if you're using a raw
pointer in an async callback you're doing it wrong, but I will reland
this CL with the callback processed in PeerConnection::OnMessage
instead as to not change the behavior of the old SRD signature.

6f36747fb1 Use local codec parameters in the answer.
Previously when creating an answer, we used the codecs from the remote list
to get correctly mapped codec id, but the side effect is that we also used
the remote codec parameters which is wrong.

With this change, we use the local codecs with local parameters and the
|NegotiateCodecs| method will take care of the codec id mapping.

6c7ec32bd6 SetRemoteDescriptionObserverInterface added.
The new observer replaced SetSessionDescriptionObserver for
SetRemoteDescription. Unlike SetSessionDescriptionObserver,
SetRemoteDescriptionObserverInterface is invoked synchronously so
that the you can rely on the state of the PeerConnection to represent
the result of the SetRemoteDescription call in the callback.

The new observer succeeds or fails with an RTCError.

This deprecates the need for PeerConnectionObserver::OnAdd/RemoveTrack
and SetSessionDescriptionObserver, with the benefit that all media
object changes can be processed in a single callback by the application
in a synchronous callback. This will help Chromium keep objects in-sync
across layers and threads in a non-racy and straight-forward way, see
design doc (Proposal 2):
https://docs.google.com/a/google.com/document/d/1-cDDC82mgU5zrHacfFz720p3xwRtuBkOPSRchh07Ho0/edit?usp=sharing

An adapter for SetSessionDescriptionObserver is added to allow calling
the old SetRemoteDescription signature and get the old behavior
(OnSuccess/OnFailure callback in a Post) until third parties switch.

9e6fd2bd47 Add streams() to RtpReceiverInterface and implementations.
This makes the receiver know about its associated set of streams, the
equivalent of the [[AssociatedRemoteMediaStreams]] slot in the spec,
https://w3c.github.io/webrtc-pc/#dfn-x%5B%5Bassociatedremotemediastreams%5D%5D

This does not change layers below peerconnection.cc. The streams are set
upon the receiver's construction and is not modified for the duration of
its lifetime.

When we support modifying the associated set of streams of a receiver
the receiver needs to know about it. The receiver's streams() should be
used in all places where a receiver's streams need to be known.

int32_t SetLoudspeakerStatus(bool enable)
int32_t GetLoudspeakerStatus(bool* enabled) const

These APIs are only implemented on iOS and they do not belong in the
native audio layer since the client can achieve the same functionality
by using the shared audio session in sdk/objc/Framework/Headers/WebRTC/RTCAudioSession.h.
It also gives the client a better flexibility in how the audio routing is done.
