Alan Cox b99348e5ea Add support for the VM_ALLOC_COUNT() hint to vm_page_alloc(). Consequently,
the maintenance of vm_pageout_deficit can be localized to just two places:
vm_page_alloc() and vm_pageout_scan().

This change also corrects an off-by-one error in the maintenance of
vm_pageout_deficit.  Historically, the buffer cache functions, allocbuf()
and vm_hold_load_pages(), have not taken into account that vm_page_alloc()
already increments vm_pageout_deficit by one.
