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).

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.

364b2673c0 Replace DatagramDtlsAdaptor with DatagramRtpTransport.
DatagramDtlsAdaptor wraps a DatagramTransport in a DtlsTransport.  This
is only used by wrapping it again, in an RtpTransport.  It is simpler to
just wrap DatagramTransport directly into an RtpTransport.

DatagramTransport is never used as a DtlsTransport, and doesn't support
most of the functionality exposed by the DtlsTransport interface.

However, it supports *all* the functionality of the RtpTransport, making
this a much cleaner fit.

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.

71c6482baf 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.

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.

6a489f22c7 Fully qualify googletest symbols.
Semi-automatically created with:

git grep -l " testing::" | xargs sed -i "s/ testing::/ ::testing::/g"
git grep -l "(testing::" | xargs sed -i "s/(testing::/(::testing::/g"
git cl format

After this, two .cc files failed to compile and I have fixed them
manually.

c84f661b10 Stop using Googletest legacy APIs.
Googletest recently started replacing the term Test Case by Test Suite.
From now on, the preferred API is TestSuite*; the older TestCase* API
will be slowly deprecated.

This CL moves WebRTC to the new set of APIs.

More info in [1].

This CL has been generated with this script:

declare -A items
items[TYPED_TEST_CASE]=TYPED_TEST_SUITE
items[TYPED_TEST_CASE_P]=TYPED_TEST_SUITE_P
items[REGISTER_TYPED_TEST_CASE_P]=REGISTER_TYPED_TEST_SUITE_P
items[INSTANTIATE_TYPED_TEST_CASE_P]=INSTANTIATE_TYPED_TEST_SUITE_P
