stagefright: add an extra buffer to ANW's BUfferQueue

Add an extra buffer to ensure video player has a free buffer to
dequeue rather than wait for the queued buffer to be displayed.
Enable logs to indicate number of buffers allocated.

NOTE: This is not needed for 30fps content on 60fps panel, But
making this change regardless for all framerates till root-cause
is identified in SF

libstagefright: Fix intermittent pause during tunnel A-V playback

-Media time is used in onVideoEvent for A-V sync. In offload
 playback we only use realtime(time from DSP).
-Media time should be same as real time. If media time is not
 updated with the real time value A-V sync issues are seen.
-Update media time to real time value to avoid intermittent pause
 during playback.
