c85ebbe766 Reland: Implement true negotiation for DatagramTransport with fallback to RTP.
In short, the caller places a x-opaque line in SDP for each m= section that
uses datagram transport.  If the answerer supports datagram transport, it will
parse this line and create a datagram transport.  It will then echo the x-opaque
line into the answer (to indicate that it accepted use of datagram transport).

If the offer and answer contain exactly the same x-opaque line, both peers will
use datagram transport.  If the x-opaque line is omitted from the answer (or is
different in the answer) they will fall back to RTP.

Note that a different x-opaque line in the answer means the answerer did not
understand something in the negotiation proto.  Since WebRTC cannot know what
was misunderstood, or whether it's still possible to use the datagram transport,
it must fall back to RTP.  This may change in the future, possibly by passing
the answer to the datagram transport, but it's good enough for now.

Negotiation consists of four parts:
 1. DatagramTransport exposes transport parameters for both client and server
 perspectives.  The client just echoes what it received from the server (modulo
 any fields it might not have understood).

 2. SDP adds a x-opaque line for opaque transport parameters.  Identical to
 x-mt, but this is specific to datagram transport and goes in each m= section,
 and appears in the answer as well as the offer.
  - This is propagated to Jsep as part of the TransportDescription.
  - SDP files: transport_description.h,cc, transport_description_factory.h,cc,
    media_session.cc, webrtc_sdp.cc

 3. JsepTransport/Controller:
  - Exposes opaque parameters for each mid (m= section).  On offerer, this means
    pre-allocating a datagram transport and getting its parameters.  On the
    answerer, this means echoing the offerer's parameters.
  - Uses a composite RTP transport to receive from either default RTP or
    datagram transport until both offer and answer arrive.
  - If a provisional answer arrives, sets the composite to send on the
    provisionally selected transport.
  - Once both offer and answer are set, deletes the unneeded transports and
    keeps whichever transport is selected.

 4. PeerConnection pulls transport parameters out of Jsep and adds them to SDP.

This reverts commit 71c6482baf0ff17141c635e6a7639493db68a65c.

Reason for revert: Lands too much at once and breaks downstream tests that need to implement new interfaces first.

292ce4ef25 Move datagram transport to JsepTransport
- This makes it consistent with ICE and MediaTransport ownership.
- Removes unnecessary datagram_transport() getter in DtlsTransportInternal

As a side effect this fixes bug in JsepTransportController, which moved datagram_transport to Dtls after creating it, then checked if (datagram_transport) to decide which RTP transport to create. As a result of this bug we were creating Sded instead of Unencrypted RTP with datagram transport.

0c1c1b4014 Move ownership of ICE from DtlsTransport to JsepTransport.
It does not make sense for DtlsTransport to own ICE, and this arrangement will
not work when negotiating datagram or DTLS transport.  During negotiation, both
a DTLS transport and a datagram transport need to be ready to receive from the
same ICE transport, depending on which protocol is chosen by the answerer.  Once
the answerer chooses a protocol, the transport that is not chosen must be
deleted, but ICE must be left intact for use by the remaining transport.

ICE states were connected to datagram transport only in bypass mode. As a result, if we received datagram state change notification before ICE state change notification, the state was not propagated.

TODO: We need fake datagram transport implementation/test so that we could unit test such failures without relying on downstream projects.

44bd71cc44 Create a composite implementation of RtpTransportInternal.
This will be used to multiplex multiple transports during SDP
negotiation.  When the offerer watns to support multiple RTP transports,
it will combine them into a singla CompositeRtpTransport.

CompositeRtpTransport can receive from any of the offered transports
while waiting for an answer to arrive.

The choice of which transport is used to send must be driven by the SDP
answer.  If a provisional answer arrives, the composite can be set to
send using the chosen transport, while maintaining other transports in
case the peer changes its mind.  When the final answer arrives, the
composite will be deleted and replaced with the chosen transport.

316f3ac13b Datagram Transport Integration
- Implement datagram transport adaptor, which wraps datagram transport in DtlsTransportInternal. Datagram adaptor owns both ICE and Datagram Transports.
- Implement setup of datagram transport based on RTCConfiguration flag use_datagram_transport. This is very similar to MediaTransport setup with the exception that we create DTLS datagram adaptor.
- Propagate maximum datagram size to video encoder via MediaTransportConfig.

TODO: Currently this CL can only be tested in downstream projects. Once we add fake datagram transport, we will be able to implement unit tests similar to loopback media transport.

0fa8605640 Add DCHECK on the port allocator in P2PTransportChannel.
Methods of P2PTransportChannel have been assuming a non-null port
allocator for a long time, and yet the constructor does not check for
that. With the recent change that wires a signal in the port allocator
to the transport in the constructor, a valid allocator becomes a must.

cd8d1cf68e Surface ICE candidates that match an updated candidate filter.
After this change an ICE agent can surface candidates that do not match
the previous filter but are allowed by the updated one. The candidate
filter, as part of the internal implementation in the ICE transport,
manifests the RTCIceTransportPolicy field in RTCConfiguration.

This new feature would allow an ICE agent to gather new candidates when
the transport policy changes from e.g. 'relay' to 'all' without an ICE
restart.

A caveat in the current implementation remains, and a candidate can
surface multiple times if the transport policy, or the candidate filter
directly, performs multiple transitions from a value that disallows to
one that allows the underlying candidate type. For example, if the
transport policy is updated by 'all' -> 'relay' -> 'all', the same host
candidate can surface after the second update.

330fbee5d8 Make ExtraICEPing send slightly fewer extras
This patch introduces a minor tweak to how often
the extra ice pings are sent.
- never send if non of the candidates is relay
- only send (extra) if it was more than 100ms
  since you sent a ping.

The motivation for this is that we measured
an regression of 0.05% in call setup success rate.

df919fb425 Don't pretend we've received an end-of-candidates indication.
