Use class sensor_device moved from hal-api-sensor

Use class sensor_device moved from hal-api-sensor

Since the usage of the hal-api-sensor is changed, sensord should be
changed according to the change of hal-pai-sensor.
Below are change of hal-api-sensor:
 * No C++ class in the header file
 * Sensor device creation function does not return sensor_device object
   but a unique ID for that sensor device object in the hal backend.
 * All methods of sensor_device is implemented as a separated C
   functions, which has same name as the original method name but has a
   prefix "hal_sensor". Also those functions should be called with
   sensor ID which is passed from creation function to distinghush
   sensor devices.

According to those changes, sensord is also changed:
 * Create a sensor_device compatible class to emulate the original
   sensor_device class.
 * Some minor changes according to the removal of some typedefs.
