I gave up on removing proxy_info, user_agent and tcp_options. I don't
think it's feasible to remove them without removing all the proxy code.
The assumption that you can set the proxy and user agent long after
you have created the factory is entrenched in unit tests and the code
itself. So is the ability to set tcp opts depending on protocol or
endpoint properties.
It may be easier to untangle proxy stuff from the factory later,
when it becomes a more first-class citizen and isn't passed via
the allocator.

This is part of a larger refactoring:
1) Add new method and provide default implementations for the other
Create* methods (this CL) so they can be removed downstream.
2) Implement new method in Chromium and remove the overrides of the
other Create* methods from subclasses of PacketSocketFactory.
3) Remove other Create* methods from PacketSocketFactory and make
the new Create method pure virtual. Make BasicPacketSocketFactory
take user_agent and proxy_info in the constructor.
4) Move the slimmed-down packet_socket_factory into api/.

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.

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.

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.

This reverts commit cd8d1cf68e4eeed71fba51c97006a91bfd41813d.
Reason for revert: breaks an internal project
Original change's description:
> 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.
