Konstantin Belousov ecfbddf0cd sysctl vm.objects: report backing object and swap use
For anonymous objects, provide a handle kvo_me naming the object,
and report the handle of the backing object.  This allows userspace
to deconstruct the shadow chain.  Right now the handle is the address
of the object in KVA, but this is not guaranteed.

For the same anonymous objects, report the swap space used for actually
swapped out pages, in kvo_swapped field.  I do not believe that it is
useful to report full 64bit counter there, so only uint32_t value is
returned, clamped to the max.

For kinfo_vmentry, report anonymous object handle backing the entry,
so that the shadow chain for the specific mapping can be deconstructed.
