Another baby step toward getting sysinstall working:
o fillin media s/h/c fields from new XML phk just added; need this because sysinstall uses them in the fdisk look-alike o add new tags to xml parser o cleanup parser a touch; remove unused tags and move tag parsing stuff to a table to simplify future additions o redo callback to pass 64-bit values since mediasize overflows u_int32_t o loosen parsing sanity checks a touch to deal with new xml we must handle o move sector size probing to non-geom handling since we now get it from xml o remove WHOLE_DISK_SLICE buggery now that we get mediasize from xml
