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.

Now we can wakeup properly if there are multiple Contiki etimers
in the system.

Refactor etimer and timer Contiki APIs to use the native
Zephyr timers. The Contiki way did not work well anyway
as we do not really have the process concept in Zephyr.

Base is from Contiki git tree at git://github.com/contiki-os/contiki.git
commit 6ac939bc58ea76aa37e9b86af55ad51cfc3434e9
This one does not do anything useful yet. It sets the baseline for
subsequent patches.
