o) Add NPDEPG, like NPTEPG but for PDEs.
o) Remove NBPG, PGOFSET and PGSHIFT. Use the standard names.
o) Remove some unused macros and move things from param.h to vmparam.h that
belong in the latter. (Actually, all of the kernel segment values, virtual
addresses, etc., belong in one place, but this is a step in the right
direction.)
