Audio loop function

[GoogleCodeExporter]

Some games' backgroud music can'loop,I have created a version base on r2957 to 
solve this problem with an experimental way. I have tested some games like 
<Busou Shinki - Battle Master MK.2> <Monster Hunter Nikki：Poka Poka Airu Mura 
G> <Digimon Adventure>,it sounds good.
These are what I change,search for "enableaudioloop" and can find what I change.

Which values are used in these games for:
- loops (all LoopInfo values)
- currentLoopNum
- loopNum
when reaching setDecodedSamples?

Does it help to add the following lines at the end of 
sceAtrac3plus.AtracID.analyzeAtracHeader() (line 366):

            if (loops != null) {
                // If a loop end is past the atrac end, assume the atrac end
                for (LoopInfo loop : loops) {
                    if (loop.endSample > atracEndSample) {
                        loop.endSample = atracEndSample;
                    }
                }
            }
