Log:
- Define private interface IPortWaveRTStreamInit in order to deal with PHYSICAL_ADDRESS as
return value
- Implement reading/writing into cyclic buffer for IPortPinWaveRT 
- Allocate an audio buffer when the pin is initialized. This needs to be changed once
KSPROPERTY_RTAUDIO_BUFFER is implemented
- Fix a bug in PcNewPort
- Remove obsolete code from IPortWavePci
- Return the allocated MDL from IPortWaveRTStream::AllocateContiguousPagesForMdl
- Create a system thread when using IServiceGroup::RequestDelayedService
- ReactOS now partly supports Vista audio driver model
