// This class allows the ICE implementation (P2PTransportChannel) to run on a
// thread different from the thread from which it is controlled. All
// interactions with the ICE implementation happen asynchronously.
//
// Terminology:
// - Proxy thread: Thread from which the P2PTransportChannel is controlled. This
//       is the thread on which the IceTransportProxy is created.
// - Host thread: Thread on which the P2PTransportChannel runs. This is usually
//       the WebRTC worker thread and is specified when creating the
//       IceTransportProxy.
//
// The client must create the IceTransportProxy on the same thread it wishes
// to control it from. The Proxy will manage all cross-thread interactions; the
// client should call all methods from the proxy thread and all callbacks will
// be run on the proxy thread.
