xenpaging: track number of paged pages in struct domain
The toolstack should know how many pages are paged-out at a given point in time so it could make smarter decisions about how many pages should be paged or ballooned. Add a new member to xen_domctl_getdomaininfo and bump interface version. Use the new member in xc_dominfo_t. The SONAME of libxc should be changed if this patch gets applied.
