MT32: Update Munt to 2.0.0

This changeset also removes unnecessary direct modifications to
Munt code to ease future updates. To update Munt in the future:

1. Replace all source files in the `softsynth/mt32` directory with
   new files from the upstream `mt32emu/src` directory;
2. Update `config.h` with the correct version number for the new
   version of Munt;
3. Update `module.mk` to match the list of sources given in
   `mt32emu/CMakeLists.txt libmt32emu_SOURCES`.
