This update uses upstream commit f88ef828a600ce66d1f730c8fb2a7f580f6f6165. This update switches to use the new Munt C++ interface, which will allow ScummVM to link to an external Munt library instead of requiring it to be built-in in the future. For the moment, the emulator is still built-in, since it is not available from most package repositories. The Munt driver in ScummVM now uses writeSysex instead of the (now-private) playSysexWithoutFraming, per recommendation from the Munt team <https://github.com/munt/munt/pull/30>. This changeset also removes direct modifications that used to be made to Munt code, to ease future updates. To update Munt code 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 add any new source files that need to be built.
