[silverblade] 34338: Partial implementation of WODM_CLOSE and WODM_WRITE handling within MME-Buddy. Test code added to sndblst.dll to mimics WinMM's behaviour. Seems OK so far. WODM_WRITE just throws a single buffer at the Sound Blaster driver, needs a lot more work. Don't yet support the WinMM open/close/data/done callbacks.

Log:
Partial implementation of WODM_CLOSE and WODM_WRITE handling within MME-Buddy.
Test code added to sndblst.dll to mimics WinMM's behaviour. Seems OK so far.
WODM_WRITE just throws a single buffer at the Sound Blaster driver, needs a
lot more work. Don't yet support the WinMM open/close/data/done callbacks.
