	* rtems.adb, rtems.ads: Refactored rtems_clock_get into 5 methods
	which are single purpose and more strongly typed.  They are:
	    rtems_clock_get_tod - Get TOD in Classic API structure
	    rtems_clock_get_tod_timeval - Get TOD in struct timeval
	    rtems_clock_get_seconds_since_epoch - Get TOD as seconds since 1988
	    rtems_clock_get_ticks_since_boot - Get ticks since boot
	    rtems_clock_get_ticks_per_second - Get ticks per second
	Also switch from using 'Unchecked_Access to 'Access.
	Added pragma Convention C as required by gcc > 4.3.
	Changed style of parenthese on subprogram calls to match GNAT.
