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.
