libstagefright: fix drainInputBuffers for FlushCompleteEmulation Quirk

Codecs which use the "requires-flush-complete-emulation" require
flushing (draining) the buffers before filling them. The change
"accelerate camera recording start up speed" has changed the order
of filling and draining the buffers which doesn't work well with
the FlushCompleteEmulation quirk

audioflinger: decline track to be offloaded if there's active one

-If multiple offload tracks are activated at the same time,
 status of the tracks can be affected by each other and results
 in unexpected behavior
-Deny subsequent track to be offloaded and fall back to sw decoder
 if there's already actived one

frameworks/av: Avoid timestamp query to AudioPlayer during reset

-Timestamp query while in reset leads to ANR in few cases.
-Destruction of mutex in AudioTrack destructor during reset and
trying to lock the destroyed mutex as part of getPosition() call
in parallel leads to ANR.
-Avoid querying for timestamp in case reset operation is in progress.
Instead use mAudioTearDownPosition to retrieve current playback
position.
