attilio d61e085348 Extend the DDB command "watchdog" with the ability to specify a timeout
value.

The timeout is expressed in the form T(N) = (2^N * nanoseconds) and can
be easilly extracted from the watchdog interface as a WD_TO_* macro.
That new functionality is supposed to fix re-entering the kernel from DDB
re-enabling the watchdog again (previously disabled) and also offer the
possibility to break for deadlocked DDB commands.

Please note that retro-compatibility is retained.
