* Add MUSIC_AUDIO_NONE to MusicContextType and format fixes
- Useful to check the context type to see if the format is recognized. Defaulting to wav causes issues where formats are assumed to
be wav.
* Fix memory issues with LoadMusicStream and UnloadMusicStream
- Set ctxType and ctxData even if the format fails to load.
- Set ctxData to NULL if it fails and check for null inside UnloadMusicStream.
- Change RL_MALLOC when loading formats to RL_CALLOC to prevent undefined behavior.
- Add NULL check when unloading xm file.
jar_xm.h does some shady pointer casts leading to unaligned accesses
and breaking strict aliasing. x86 has special circuitry for doing
unaligned accesses, but on other architectures, it may trap and require
kernel fix-up or crash outright. With this patch, one obstacle in
porting raylib to the GameBoy Advance has been removed. Go for it ;-)
To avoid having to rewrite that `mempool' code, insert padding before
structs and instruct the compiler (GCC, most importantly), to be gentle
when optimizing.
This fixes#490 (Unless we got ourselves 256-bit pointers, if so,
hello future!)
Moved all external libraries used by raylib to external folder inside
raylib src. Makefile has already been update and also the different
includes in raylib modules.
