First attempt at bringing in bus_space.9 from NetBSD.

Changes from NetBSD bus_space.9 v1.15:

1) All references to the following functions were '.\"'d out:

	bus_space_read_raw_multi_1
	bus_space_read_raw_region_1
	bus_space_read_stream_1
	bus_space_read_stream_2
	bus_space_read_stream_4
	bus_space_read_stream_8
	bus_space_vaddr
	bus_space_write_raw_multi_1
	bus_space_write_raw_region_1
	bus_space_write_stream_1
	bus_space_write_stream_2
	bus_space_write_stream_4
	bus_space_write_stream_8

2) All references to the following defines were '.\"'d out:

	BUS_SPACE_MAP_PREFETCHABLE
	BUS_SPACE_MAP_LINEAR

3) The entire COMPATIBILITY section with its discussion of of
   __BUS_SPACE_COMPAT_OLDDEFS was deleted as __BUS_SPACE_COMPAT_OLDDEFS
   does not seem to be used at all anywhere in the tree.

4) Added the already documented bus_space_alloc() to list of functions
   at head of page

5) Added bus_space_set_multi_N(t,h,o,v,c) definitions and descriptions

6) Renamed bus_space_copy_region_N to bus_space_copy_N

7) Replaced *_stream_* documentation with *_raw_* documentation

8) Rename the parameter 'flags' in bus_space_map and bus_space_alloc
   to 'cacheable' as that's the only flag we provide. Other more
   descriptive parameter names were retained rather than change to
   terse one/two letter parameter names used in bus.h

9) Eliminated short lines, made all new sentences start
   on new line, deleted extraneous .Pp's, removed some excess
   parenthesis, trailing white space, etc.


** Issues with bus_space.9 **

vax/bus.h and mac68k/bus.h still define

   bus_space_copy_region_N()

instead of

   bus_space_copy_N

like other architectures, though some of the comments do refer to
bus_space_copy_N.

powerpc/bus.h still defines

   bus_space_read_raw_multi_1()
   bus_space_write_raw_multi_1()

vax/bus.h still defines

	BUS_SPACE_MAP_PREFETCHABLE

while vax/bus.h and mac68k/bus.h both still define

	BUS_SPACE_MAP_LINEAR
