Josarn 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

Joakim Nohlgård b365ab45cb 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.

Kaspar Schleiser a719e7d61f sys: xtimer: some updates 
- more robust underflow protection in xtimer_usleep_until()
- use relative target in xtimer_spin()
- honour reference in isr when spinning until timer target
- add XTIMER_BACKOFF to xtimer_spin_until() target when backing off in
  _timer_set_absolute()
- doxygen updates
