James Teh a6bb69bf42 Bug 1416986 part 1: Allow an mscom Handler to signal that it knows an interface is definitely not available. r=aklotz
If QueryHandlerInterface returns E_NOINTERFACE, the proxy will be queried for the interface.
However, the handler might know that the interface is definitely not available and could thus avoid a pointless cross-process call.
To facilitate this, the handler can now return S_FALSE to signal that the proxy should not be queried, thus immediately returning E_NOINTERFACE to the client.
