-Looping syncslaves are stopped when there is no syncmaster.
-Hardened against edge cases regarding soundsource priority sorting.
-Fixed issue with syncmasters being marked as having looped when instead they just started playing (caused double-start of syncslaves).
-Updated some comments.
-Idle tick is now responsible for dispatching all pending sound sources, as such improves priority sorting.
-Added ui sound precache mechanisms (to fetch sounds without associated soundsources)
-Audio engine no logner available pre-login or upon disconnect, for simplicity.
-General cleanup to the audio engine/impl.
-Fixed some gAudiop calls that were lacking prerequisite null checks.
-Added 'isUpstreamOK' procuedure to LLAssetStorage to allow avoidance of making requests when there is no upstream host connection.
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.
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.
