177aa22bcd webrtc: Initial support for stream addition/removal 
Limitations:
- No transport changes at all (ICE, DTLS)
- Codec changes are untested and probably don't work
- Stream removal doesn't remove transports (i.e. non-bundled transports
  will stay around until webrtcbin is shutdown)
- Unified Plan SDP only. No Plan-B support.

c3c4b07ad3 webrtc/transceiver: add a set_direction function 
Matches the setDirection() from the W3C spec and allows changing the
transceiver direction at the next negotiation cycle.

1894293d63 webrtcbin: an element that handles the transport aspects of webrtc connections 
SDP's are generated and consumed according to the W3C PeerConnection API
available from https://www.w3.org/TR/webrtc/

The SDP is either created initially from the connected
sink pads/attached transceivers as in the case of generating an offer or
intersected with the connected sink pads/attached transceivers as in
the case for creating an answer.  In both cases, the rtp payloaded streams
sent by the peer are exposed as separate src pads.

The implementation supports trickle ICE, RTCP muxing, reduced size RTCP.
