SHFMODExStreamBufferSize added. Determines stream buffer size in ms. (stream restart required) SHFMODExDecodeBufferSize added. Determines decode buffer size in ms. (stream restart required) Streams will mute themselves if they are starving, until they are free of starvation for 5 full seconds. Streams that fail to accumulate any buffer progress while starving for 10 full updates will be stopped. Stream buffer progress(buffer percent) is llinfos spewed every update. (temporary) Doubled default stream buffer size Increased default decode buffer size to 1000ms (from 400) Temporarily using FMOD::Memory_Initialize to display raw stream/decode buffer sizes via llinfos. Added llwarns messages for SigmaTel hardware or bad audio acceleration configuration.
