No callers, no functional change.

This function will probably die before ever being called
from the in-tree code, since hibernate will move to RLE encoding.
No functional change, function had no callers.

This is so I can move the pig allocator to subr_hibernate.
No functional change.

1) Make the pagedaemon aware of the memory ranges and size of allocations
where memory is being requested, and pass this information on to
bufbackoff(), which will later (not yet) be used to ensure that the
buffer cache gets out of the way in the right area of memory.
Note that this commit does not yet make it *do* that - as currently
the buffer cache is all in dma-able memory and it will simply back
off.
2) Add uvm_pagerealloc_multi - to be used by the buffer cache code
for reallocating pages to particular regions.

recommit pmemrange:
physmem allocator: change the view of free memory from single
free pages to free ranges. Classify memory based on region with
associated use-counter (which is used to construct a priority
list of where to allocate memory).
Based on code from tedu@, help from many.
Useable now that bugs have been found and fixed in most architecture's
pmap.c
ok by everyone who has done a pmap or uvm commit in the last year.
