Added new functions to the debugger API:

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.

We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.
