	* libblock/src/ide_part_table.c: Fixed NULL pointer access.
	* libmisc/monitor/mon-command.c, libmisc/monitor/mon-editor.c,
	libmisc/monitor/mon-monitor.c, libmisc/monitor/monitor.h,
	libmisc/shell/cmds.c: The list of registered monitor commands is now
	private and only accessible via a lookup and iterate function.
