MFC 261811,282660,282706:
Place VM objects on the object list when created and never remove them.
261811:
Fix function name in KASSERT().
282660:
Place VM objects on the object list when created and never remove them.
This is ok since objects come from a NOFREE zone and allows objects to
be locked while traversing the object list without triggering a LOR.
Ensure that objects on the list are marked DEAD while free or stillborn,
and that they have a refcount of zero. This required updating most of
the pagers to explicitly mark an object as dead when deallocating it.
(Only the vnode pager did this previously.)
282706:
Satisfy vm_object uma zone destructor requirements after r282660 when
vnode object creation raced.
