[ros-diffs] [silverblade] 34595: Beginning of MME audio support rewrite. Made the message entrypoints thread-safe. Refactored parts of the code, in particular the device I/O handling. Uniformly implemented the GETNUMDEVS message for all device types (wave/midi/mixer/aux). Pops up message boxes for each device found. Tested on NT4. Removed lots of redundant debug code.
