Introduce the KDB debugger frontend.

Besides providing services to backends, it also serves as the single point of contact for any and all code that wants to make use of the debugger functions, such as entering the debugger or handling of the alternate break sequence. For this purpose, the frontend has been made non-optional. All debugger requests are forwarded or handed over to the current backend, if applicable. Selection of the current backend is done by the debug.kdb.current sysctl. A list of configured backends can be obtained with the debug.kdb.available sysctl. One can enter the debugger by writing to the debug.kdb.enter sysctl.
