Log Message:
Updated libwildmidi to 0.4.0.

This is a major milestone release!

We worked hard over the years to improve WildMIDI by looking at
how it is used downstream and working with them to offload their
MIDI-related burdens and pushing them to WildMIDI. We've included
support for the following MIDI-like formats: HMI, HMP, KAR, MIDI
Type 2, MUS and XMI. We've expanded our API to help facilitate
error detection, logging and on-the-fly conversion from MIDI-likes
to MIDI without having to initialize the library first.

What's new in 0.4.0:

    API change: The library now returns audio data in host-endian format, not \ 
little-endian.
    API change: WildMidi_GetVersion() added to the api, along with new numeric \ 
version macros in the wildmidi_lib.h header. the dso version is changed from 1 \ 
to 2.
    API change: All long or unsigned long type _WM_Info fields changed into \ 
strictly 32bit fields (int32_t or uint32_t.)
    API change: WildMidi_OpenBuffer() and WildMidi_GetOutput() changed to accept \ 
strictly 32bit size parameters, i.e. uint32_t, instead of unsigned long.
    API change: WildMidi_ConvertToMidi() and WildMidi_ConvertBufferToMidi() \ 
added for MIDI-like files to be converted to MIDI.
    API change: WildMidi_SetCvtOption() added to support conversion options.
    API change: WildMidi_SongSeek() added to support Type 2 MIDI files.
    API change: WildMidi_GetLyric() added to support embedded text, such as KAR \ 
files.
    API change: WildMidi_GetError() and WildMidi_ClearError() added to cleanly \ 
check for, retrieve and clear error messages. They no longer go to stderr.
    Support for loading XMI (XMIDI format) files, thanks Ryan Nunn for releasing \ 
his code under the LGPL.
    Support for loading MUS (MUS Id format) files, such as from Doom.
    Support for loading HMP/HMI files, such as from Arena and Daggerfall.
    Support for loading KAR (MIDI with Lyrics) and Type 2 MIDI files.
    Build requires cmake-2.8.11 or newer now.
