setrunqueue(), but remrq() was never renamed. Rename remrq() to
remrunqueue(). Also, move remrunqueue() prototype from vm/vm_extern.h
to sys/proc.h, so that it's in the same place as the setrunqueue() prototype
and other related prototypes.

Don't declare pmap_page_index for now. It will break the arm port.
...
This clearly needs to be fixed. I would like to declare it:
__pure u_int pmap_page_index __P((vm_offset_t));
but at least the arm port wants it signed [since it tests for -1 all over
the place]. Can we have this fixed please?

Extend use of vm_object_prefer() to vm_allocate_with_pager().
...
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.
Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.
