* more robust ov_callbacks, fixes OGG Vorbis playback in some Libretro platforms, disable multiple OGG at once on GC/Wii/Wii U libretro
Not sure but it seems the libretro VFS implementation/stuff breaks OGG playback in some Libretro platforms (mostly GameCube/Wii/Wii U)...
Also disables multiple OGG files open at once in the libretro cores for GC, Wii, and Wii U, as it could also cause OGG playback issues.
Thanks to irixxxx for helping with this fix.
