WildMIDI 0.4.6

Bug-fix and maintenance update after the previous version 0.4.5.
All users of wildmidi-0.4.x are encouraged to upgrade.

What's new in 0.4.6:

• A lot of player cleanup and refactoring, thanks to initial work
  by Azamat H. Hackimov, with addition of several safeguards and
  minor fixes.
• Ability to choose which audio output backends to include in the
  build system: see the cmake script for the relevant WANT_???
  options. Player's --help command line switch lists the available
  backends. Thanks to initial work by Azamat H. Hackimov.
• New native audio output backends for player: coreaudio for macOS,
  sndio for OpenBSD, netbsd (sunaudio) for NetBSD.
• Improved pkg-config file generation in cmake script (bug #236).
• Workaround a link failure on AmigaOS4 with newer SDKs (bug #241).
• Other minor source clean-ups.
• CMake project clean-ups. Cmake v3.4 or newer is now required.
