Be more careful about cleaning up the stack after function calls early
in the boot. The cleanup must be done in one of the few ways that db_numargs() understands, so that early backtraces in ddb don't underrun the stack. The underruns caused reboots a few years ago when there was an unmapped page above the stack (trapping to abort the command doesn't work early). Cleaned up some nearby code.
