To intercept COM IPC, we provide an `IChannelHook` interface to `CoRegisterChannelHook`, which gives us notifications about COM IPC that we can use to insert profiler markers. Note that `IChannelHook` is not documented on MSDN, however it is defined in the SDK header files. When the profiler is available, once XPCOM is up: * If the profiler is active, we immediately register the channel hook; * Otherwise we register an observer and hold off on registering the hook until the profiler is started, at which point we register the hook and remove the observer.
