give better support to the bios memory maps.

provide memory maps editing through the machine memory command.
rearrange probing in machdep, so it provides less output,
also giving a shot for apm to fix the memory maps.
changes to kernel are minimal, only that is required due
to the api version bits addition and such cosmetic changes.
tested on all critical kernel,boot combinations; niklas@ ok
