We need to keep track of local variables that reference other variables that hold disposable objects. The rule should not get triggered if we return one of these local variables. The Mono 3.2 compiler occasionally introduces such local variables.
Properties can return IDisposable objects, so we need to check those as well, otherwise we report false positives.
We shouldn't report an error if we temporarily store an object in a (new) variable and then return that. The Mono 3.2 compiler produces such code in debug mode.

Don't complain that dispose is not guaranteed if we return an object of that type. This catches the case where we dispose an object in a catch block that we otherwise return.
When a field gets assigned a disposable object created with initializers we shouldn't report this as failure.
