Log message:
	* src/hal_if.c (delay_us): The first test against
	CYGNUM_KERNEL_COUNTERS_RTC_PERIOD is now against the period
	divided by two. By the time we get to this test we know that usecs
	can never be > usec_per_period/2 so we can double the range of
	period values that we can handle without overflow and use the more
	efficient approximation. The second test is not changed since we
	cannot make the same assumptions about the elapsed count.
