hal_get_time() gave wrong values if the SysTick counter reached 0 between reading overflowcnt and calling systick_get_value(). This behavior is now addressed by retrying if that happens. Thanks to djb for pointing that out to us. The reset value is also increased to the maximum of 2^24-1, such that there is less overhead from the interrupt handler, and overflowcnt is marked volatile.
