Add support for VM_ALLOC_WIRED and VM_ALLOC_ZERO to vm_page_alloc_freelist()
and use these new options in the mips pmap.
Wake up the page daemon in vm_page_alloc_freelist() if the number of free
and cached pages becomes too low.
Tidy up vm_page_alloc_init(). In particular, add a comment about an
important restriction on its use.
