Macros
#define	XTIMER_MIN_SPIN _xtimer_usec_from_ticks(1)
	Minimal value xtimer_spin() can spin.

#define	MSG_XTIMER 12345
	IPC message type for xtimer msg callback.

volatile uint64_t	_xtimer_current_time

static uint32_t	_xtimer_lltimer_now (void)
	returns the (masked) low-level timer counter value.

static uint32_t	_xtimer_lltimer_mask (uint32_t val)
	drop bits of a value that don't fit into the low-level timer.

uint32_t	_xtimer_now (void)
	xtimer internal stuff

void	_xtimer_set64 (xtimer_t *timer, uint32_t offset, uint32_t long_offset)

void	_xtimer_periodic_wakeup (uint32_t *last_wakeup, uint32_t period)

void	_xtimer_set_wakeup (xtimer_t *timer, uint32_t offset, kernel_pid_t pid)

void	_xtimer_set_wakeup64 (xtimer_t *timer, uint64_t offset, kernel_pid_t pid)

void	_xtimer_tsleep (uint32_t offset, uint32_t long_offset)
	Sleep for the given number of ticks.
