[silverblade] 38514: Split NT4-specific part of MME-Buddy off into its own support library (using NT4 audio driver IOCTLs for unspecified functions was a stupid idea.) Reimplemented routines for querying wave format, setting wave format, and opening/closing devices. The new implementation can cater for multiple instances of a sound device.
