* Function: AllocateBuffers
*
* Description: allocate all the memory needed for the MP3 decoder
*
* Inputs: none
*
* Outputs: none
*
* Return: pointer to MP3DecInfo structure (initialized with pointers to all
* the internal buffers needed for decoding, all other members of
* MP3DecInfo structure set to 0)
*
* Notes: if one or more mallocs fail, function frees any buffers already
* allocated before returning
*
* Changed by Kasper Jepsen to support static buffers as well.
