webrtcsrc: add support for navigation events
This provides support GstNavigation events handling in webrtcsrc so that a GStreamer client can be used to control remotely a GStreamer server, similar to how the web client is capable of controlling a wpesrc. This is part of a larger set of patches that require more work on the sinks and sources.
server: d3d11screencapturesrc ! webrtcsink enable-data-channel-navigation=true
client: webrtcsrc enable-data-channel-navigation=true ! d3d11videosink
