[Openal] ALUT import for different wav formats

[developer at oldunreal.com]

Gave it short look, but it doesn't seem to provide either what i need. 
As a matter of fact, i need exactly what alutLoadMemoryFromFileImage is 
supposed to do, but simply not provides:


      alutLoadMemoryFromFileImage


        Name

alutLoadMemoryFromFileImage - convert in-memory sound data into 
OpenAL-like data


        Synopsis

ALvoid *alutLoadMemoryFromFileImage (const ALvoid *data,
                                     ALsizei length,
                                     ALenum *format,
                                     ALsizei *size,
                                     ALfloat *frequency);

alutLoadMemoryFromFileImage tries to guess the sound data format by 
looking at the contents of the memory region given as the first two 
arguments and loads the sound data into a newly malloced buffer, 
possibly converting it in the process. The format is guaranteed to be a 
standard OpenAL format afterwards.
