Added basic decoding functionality to test.
Refactored some code to stop 3DS specific code from compiling on
GNU/Linux.
Tested working by running the test executable on GNU/Linux. Vorbis
decoding has many errors detected by valgrind (but still decodes
successfully).
Opus, flac, and mp3 decoding work without errors.
