- Remove dead code

- Silence a few debug prints
- Implement Dispatch_FastRead, Dispatch_fnFastDeviceIoControl
- Change _InterlockedXXX to InterlockedXXX
- Store IPortPinWaveCyclic pins in an array and close pin on a new create request (fixes a memory leak)
- Complete the close irp when the stream has really been closed
