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

sys/xtimer: Avoid race incrementing multiple periods in _timer_callback
...
On a fast CPU with a slow timer (e.g. XTIMER_SHIFT > 0) it is possible
that now == _xtimer_now() when spinning for the overflow. In the extreme
case When this happens _next_period() will be called more than once
until the timer overflows for real.
Fault observed in real life when running on a 32.768 kHz timer on a
~96 MHz clocked mulle (Kinetis K60, Cortex-M4). _next_period() was
called 9 times during the same ISR call before the 32 kHz timer
overflowed.
