Change the kernel mmap interface so that the offset to map is an
...
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

Add a macro to check for sufficient pointer alignment in bus.h context,

"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

bus_space(9), if drivers want it (they shouldn't; easy to convert) they
can define it right before including bus.h. There's been a release since
the interfaces were (slightly) changed, and no code in the source tree
uses the old interfaces as far as I can tell.
