stagefright: Adjust confidence threshold for extended sniffers

 * Some sniffers return 0.2 for cases where they only find an audio
   track in some containers.
 * Change the comparison to also examine files right on this threshold.
 * This allows us to score ONE FUCKING HUNDRED PERCENT on the Antutu
   Video Test \o/

libstagefright: align YV12 for software codecs on exynos4

YV12 chroma stide should be aligned to 16 according to the
android framework. But, GSC & Mali couldn't accept a seperate
stride for U & V components. They just use Y_stride/2 as a
UV Stride.

Prevent ANR when AudioTrack is paused or re-routed

If ClientProxy was interrupted by AudioTrack::pause() just before futex syscall() in obtainBuffer() was called,
It will not call releaseBuffer to wake up AudioTrackThread.
It puts the AudioTrackThread to sleep and then a deadlock occurs.

In this case, CBLK_INTERRUPT flags can't prevent a deadlock,
so this patch set mFutex to FUTEX_WAKE during interrupt() to avoid deadlock.

A similar problem could occur due to re-route or recovery after mediaserver death.
