timer_expired uses the nano_timer_test API to determine whether a
timer has expired. This API calls the private function
_nano_timer_expire_wait which returns the timer user data if this
timer has expired. Unfortunately _nano_timer_expire_wait clears the
user data pointer after returning it.
Therefore if timer_expired is called several times for the same timer
and if this timer has already expired then only the first call returns
the expected value (true). Other calls always return false.
In ipv6 this bug can be seen with the uip_ds6_periodic timer. Indeed
when expired this timer is going to be checked at least twice by
etimer_process function and the tcpip eventhandler function. Thus the
final uip_ds6_periodic callback is never called.
The fix consists in adding a expired field in the timer struct and
make timer_expired retain the nano_timer_test result when the timer
has expired.

We need to check the timer expiration properly. The nano_timer_test()
will return user data to caller if the timer is expired.
The issue that is fixed by this commit started to appear after
the commit 9b2452047d which combined
nano_timers and nano_timeouts.

The network timers will now use the fiber wakeup to let the
network timer fiber to get the next event. This enables the
timer fiber to sleep much longer and only wakeup when there
is something to do.

We need to export ctimer_process so that net_core.c can
call it and let it set the corresponding event timers.
Without this the timers would not be called properly.

This mega patch changes how Contiki uses buffers. In standard
Contiki there is only couple of static and global buffers.
This makes the stack non-reentrant and only usable in one
thread. This patch replaces the global buffer with buffer
supplied by caller (net_buf.h). The Contiki stack is still not
fully re-entrant after this (packet reassembly needs more TLC)
but it is a good start.
