table-based QueryInterface

[Pierre Phaneuf]

Is there a table-based QueryInterface somewhere in there? There was talk
of them at a time, but I don't remember seeing any...

I have a GenericComponent shim template in XPLC that currently
implements AddRef and Release, but I would like to add the
QueryInterface to that, that'd be so nice! :-)
