lib{xc,xl}: Seed grant tables with xenstore and console grants
This patch claims one reserved grant entry for the console and another
for the xenstore. It modifies the builder to fill in the grant table
entries for the console and the xenstore.
Previous versions of this patch have been sent to xen-devel. See
