Separate WildMidi mixing from event handling - In order to use ZDoom's own MIDI sequencer event handling must be completely separate from mixing, but WildMidi had them intertwined because it wasn't designed for external sequencers. - Also remove all 'long's defining the output buffers to avoid having something that's 32 bits wide on Windows and 64 bits wide on Linux.

Use critical sections for WildMidi locking ...because when you're trying to be thread-safe, it's generally a good idea to use mechanisms that work across multiple processor cores.

// No error if trying to shut down an uninitialized device.

- added WildMidi library sources - all converted to C++ so that they can later interface with ZDoom's own MIDI code. Also redid the file loading function to use ZDoom's FileReader instead of low level IO.
