a proper branch for fixing issues of sceMp3
1. The voice speed issue (eg. "Hanayaka Nari Wa ga Ichizoku" https://github.com/hrydgard/ppsspp/issues/5213) should be ok.
2. Downstream Panic is all right.
3. Improve ffmpeg callback function to correctly control loops and buffer copies.
Merge branch 'sceMp3_fix' into master_0.9.8
