Added a new timer function which can be used similar to the BeOS kernel add_timer function.

The difference is that these callback functions will be executed in thread (not interrupt) context,
and that they shouldn't crash (as add_timer does).
Integrated the timer funtions into the timeout() and untimeout() FreeBSD emulation framework.
