/**
* @brief Sets the timer to the appropriate timer_list or list_head.
*
* @note The target to set the timer to has to be at least bigger then the
* ticks needed to jump into the function and calculate '_xtimer_now()'.
* So that 'now' did not pass the target.
* This is crucial when using low CPU frequencies and/or when the
* '_xtimer_now()' call needs multiple xtimer ticks to evaluate.
*
* @param[in] timer pointer to xtimer_t which is added to the list.
* @param[in] target Absolute target value in ticks.

The application will mix calls to the following xtimer functions:
- `_xtimer_set`
- `_xtimer_set_absolute`
- `_xtimer_periodic_wakeup`
- `_xtimer_spin`
