xl: extend autoballoon xl.conf option with an "auto" option
autoballoon=1 is not recommened if dom0_mem was used to reduce the
amount of dom0 memory. Instead of requiring users to change xl.conf
if they do this, extend the autoballoon option with a new choice:
"auto".
With autoballoon="auto", autoballooning will be disabled if dom0_mem
was used on the Xen command line.
For consistency, accept "on" and "off" as valid autoballoon options (1
and 0 are still accepted).
The default remains "on" for now.
