cameraservice: Resolve message vs start/stop preview races

Move the mutex in start/stopPreview to include the metadata message
management. Fast start/stop sequences could (and would) eventually
cause the messages to be enabled/disabled out of sequence (or while
the camera wasn't ready for it)

Fixes BACON-173

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
