xc: export outstanding_pages value in xc_dominfo structure.

This patch provides the value of the currently outstanding pages
claimed for a specific domain. This is a value that influences
the global outstanding claims value (See patch: "xl: 'xl info'
print outstanding claims if enabled") returned via
xc_domain_get_outstanding_pages hypercall. This domain value
decrements as the memory is populated for the guest and
eventually reaches zero.

This patch is neccessary for "xl: export 'outstanding_pages' value
from xcinfo" patch.
