Start bringing i386/pmap.c into line with cleanups that were done to

alpha pmap.  In particular -
- pd_entry_t and pt_entry_t are now u_int32_t instead of a pointer.
  This is to enable cleaner PAE and x86-64 support down the track sor
  that we can change the pd_entry_t/pt_entry_t types to 64 bit entities.
- Terminate "unsigned *ptep, pte" with extreme prejudice and use the
  correct pt_entry_t/pd_entry_t types.
- Various other cosmetic changes to match cleanups elsewhere.
- This eliminates a boatload of casts.
- use VM_MAXUSER_ADDRESS in place of UPT_MIN_ADDRESS in a couple of places
  where we're testing user address space limits.  Assuming the page tables
  start directly after the end of user space is not a safe assumption.
There is still more to go.
