uvm constraints. Add two mandatory MD symbols, uvm_md_constraints
which contains the constraints for DMA/memory allocation for each
architecture, and dma_constraints which contains the range of addresses
that are dma accessable by the system.
This is based on ariane@'s physcontig diff, with lots of bugfixes and
additions the following additions by my self:
Introduce a new function pool_set_constraints() which sets the address
range for which we allocate pages for the pool from, this is now used
for the mbuf/mbuf cluster pools to keep them dma accessible.
The !direct archs no longer stuff pages into the kernel object in
uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages.
Tested heavily by my self on i386, amd64 and sparc64. Some tests on
alpha and SGI.
