libstagefright: customize delay to post video events

Calculate delay as a function of lateness rather
than fixed 10ms.
When video frames are decoded quite early, this
change will delay the wake up of video events.

We save some unwanted wake up of video events
which save power.

audioflinger: OffloadThread state fix

When switching from one offload session to another that
reuses the same offload output, audio HAL is paused & flushed in
preparation for the new track.

OffloadThread must reset mHwPaused to allow proper state transitions
for the second track.
