bce45fd9d8 xtimer/xtimer.c: xtimer_mutex_lock_timeout fix test 
Handling timeout smaller than XTIMER_BACKOFF (the timer spins) when the mutex is already locked.
This fixes the test tests/xtimer_mutex_lock_timeout/main.c:mutex_timeout_spin_locked.

f3b13cf90c xtimer: check in timeout callback if thread blocked on mutex 
Prevent a possible race condition when _mutex_timeout fires just after the
mutex was locked but before the xtimer was removed

The flow

int xtimer_mutex_lock_timeout(mutex_t *mutex, uint64_t timeout) {
   ...
    mutex_lock(mutex);
    /* mutex locked */
    /* _mutex_timeout fires and tries to remove thread from mutex queue */
    /* DEBUG: simulate callback call between lock and remove */
    xtimer_spin(xtimer_ticks_from_usec(timeout*2));
    xtimer_remove(&t);
    ...
}

sys/xtimer: Remove dependency to core_msg 
When module `core_msg` is not used, `xtimer` now no longer provides the features
related to messages. This allows using `xtimer` without `core_msg`.

672368954e xtimer: timer & target overflow, hang resolved. 
1. When the 32 bit target of the xtimer overflowed the timer was not placed in the right list.
2. When the hardware timer overflowed the comparison was wrong for setting next target.

3. Backoff condition
