 The CLOCK_MONOTONIC time services use currently the clock tick based
 watchdog. This is a problem in case the uptime (measured via the
 timercounter) and the ticks since boot drift away (measured via the clock
 ticks).  Introduce a new watchdog which uses the uptime. The memory
 overhead is quite small (two pointers per processor).
