Added stricter checking for fmodex errors. Demote a harmless message from llinfos to lldebugs when audio buffers are all consumed. Initialize LLAudioBuffer member variables. -LLAudioBuffer::mInUse is inited to TRUE to avoid buffers that just got created from getting deleted during the same frame by new audio sources further down the chain.
