32 bit low level drivers now use a Unicode interface (used to be ANSI):
- Send the *_GETDEVCAPS messages in unicode format from the
  *GetDevCapsW function and call the *GetDevCapsW from their respective
  Ansi versions.
- Modify all low level drivers to correctly process the *_GETDEVCAPS
  messages as unicode.
- *_GETDEVCAPS messages are now mapped from/to unicode for 16 bit code.
- Removed all SoundBlaster naming oldies.
Better use of some unicode functions (instead of Ansi) in winmm.
