- Fixed buffer overflow in IFilterMapper2::RegisterFilter. 

- Fixed buffer overflow in DEVENUM_IPropertyBag_Read.
- Fixed NULL pointer de-ref in DllRegisterServer when IFilterMapper2
  is not registered.
- Allowed returning the moniker in IFilterMapper2::RegisterFilter.
- Enumerate special categories without causing infinite loop.
