- Change contigmalloc() to use the vm_paddr_t type instead of an unsigned

  long for specifying a boundary constraint.
- Change bus_dma tags to use bus_addr_t instead of bus_size_t for boundary
  constraints.

These allow boundary constraints to be fully expressed for cases where
sizeof(bus_addr_t) != sizeof(bus_size_t).  Specifically, it allows a
driver to properly specify a 4GB boundary in a PAE kernel.

Note that this cannot be safely MFC'd without a lot of compat shims due
to KBI changes, so I do not intend to merge it.
