implement separate PAE pmap that allows access to 64g of physmem
if supported by the cpu(s). currently not enabled by default and
not compiled into ramdisks. this grows paddr_t to 64bit but yet
leaves bus_addr_t at 32bits. measures are taken to favour dmaable
memory allocation from below 4g line such that buffer cache is
already allocated form below, pool backend allocator prefers lower
memory and then finally bounce buffers are used as last resort.
PAE is engaged only if global variable cpu_pae is manually set
to non-zero and there is physical memory present above 4g.
simplify pcibios address math to use u_long as we always will
be in the 32bit space.
