682744 - Sprinkle some do_QueryObject fairy dust around the tree

Status: RESOLVED FIXED

(Core :: General, defect)

Back in the days before do_QueryObject, you had to write:

nsCOMPtr<nsIFoo> = do_QueryInterface(static_cast<nsIBar>(someVariableOfAConcreteType));

These days, you can just write:

nsCOMPtr<nsIFoo> = do_QueryObject(someVariableOfAConcreteType);

The MXR query shows some usages that haven't been converted, and I'm pretty sure all of them can be converted.
