libstagefright: Drain input buffer on resume

* Buffers returned from codec in paused state are
  not drained. When codec is resumed these buffers
  are not drained until the next flush, and may
  cause timed out issue.
* Added change to drain input buffers for sw
  decoders when resuming.

camera: Fix the heap corruption issue

 * Add locking around flatten/unflatten because they alter mMap and
   all hope and sleep is lost if it changes while we're iterating.
 * It's even worse if the memory backing the params string changes
   underneath of us :(
