Change #6684: Cutting point overrides for music base sets

This improves bad looping of title screen song from Windows TTD, and fixes
a long silence at the end of "Can't get there from here" from Windows TTD.

Feature: Decoder for DOS version music

This is based on reverse-engineering the TTD DOS driver for General MIDI music.

Codechange: Pass a MusicSongInfo struct instead of bare filename to music drivers.

Preparation for later extending the info passed to music drivers.

Change: [Win32 MIDI] Reset pitch bend range controllers on song change

Some songs (at least one in OpenMSX) use the MIDI pitch bend range controllers
but don't reset these at the end. This causes all subsequent songs to sound
wrong.

Change #6685: Replace Win32 music driver with one not depending on MCI

MCI MIDI is poorly supported on newer versions of Windows and can cause large
delays at the beginning of tracks.

The new driver is based on a from-scratch reader for Standard MIDI Files. This
should be re-usable in other music drivers too, and can allow for finer control
of playback in general.

It also provides a better framework for reading MIDI data from other formats
than just SMF.
