openal-1.13 静态编译(mingw32)

1.CMakeLists.txt           SET(LIBTYPE SHARED) 改成 SET(LIBTYPE STATIC)
2.include/al/al.h          删除 dllexport 
3.include/al/alc.h         删除 dllexport 
4.alc/bs2b.c               bs2b_set_level 改成 bs2b_set_level2 ...
5.OpenAL32/Include/bs2b.h  bs2b_set_level 改成 bs2b_set_level2 ...

修改 openal/bs2b 是为了避免静态编译时与原来的 bs2b 发生冲突
