[BDAPLGIN]

- Set output variable to null to fixup lazy callers
[KSPROXY]
- Enumerate input / output pins and their names
- Start implementing input / output pin
- Implement IEnumPins interface for CKsProxy filter
[MSDVBNP]
- Fix a bug (IEnumPins::Next should increase reference count on pin)
- Fix a bug (IPin::QueryFilterInfo should increase reference count on parent filter)
- Reference leakage is now fixed
