Mark Johnston 0fd977b3fa Add a return value to vm_page_remove().
Use it to indicate whether the page may be safely freed following
its removal from the object.  Also change vm_page_remove() to assume
that the page's object pointer is non-NULL, and have callers perform
this check instead.

This is a step towards an implementation of an atomic reference counter
for each physical page structure.
