The previous change causes a build issue as there is subclass of TransportChannel in chromium. To break the circular dependency, a stub of implementation for GetState() is provided and will be removed once the jingle_glue::MockTransportChannel has the function defined.

Previously, IceState is considered completed when there is only one connection (and the rest was trimmed). However, since the trimming logic is only done within the scope of network, when IPv6 and IPv4 both exist, the completion event is never fired.
This change adds the GetState() to each channel and it could decide what Completion means. The transport object then aggregates all channels before determining it's completed.
Each channel's IceState will be aggregrated at Transport level for overall Ice state
