Camera2: Basic ZSL and precapture trigger support.
- Add capture sequencer to control still image capture process
- Use precapture trigger for standard capture in sequencer
- Add infrastructure for reprocessing streams
- Add ZSL processor to maintain ZSL queue
- Add ZSL capture sequence to sequencer
This patch sets up ZSL mode and precapture triggers.
For now, to enable zsl mode, set the system property camera.zsl_mode
to 1.
