libhardware: introduce camera HAL header

camera.h

-- a HAL module for the camera, camera_module_t, which can be queried for the
   number and orientation of the available camera sensors.  A camera sensor is
   also opened through this module, and is represented by:

-- a HAL device for each camera sensor, camera_device_t, which encapsulates all
   the functionality of the base class CameraHardwareInterface;
