Commit in reactos/lib/winmm/wavemap on MAIN
wavemap.c+166-401.1 -> 1.2
Sync to Wine-20040615:
Robert Reif <reif@earthlink.net>
- Added tracing to all functions.
- Added error explanations.
- Changed debug channel from msacm to wavemap so not confused with
  msacm.
- Handle case where partial structure update requested.
- Minor white space cleanup.
- Returns proper error code when trying to get caps when no devices
  present.
- Fixed a bug where wrong a return value was returned when mapping is
  not possible.
