0f810ef0a2 Merge amd64 and i386 bus.h and move the resulting header to x86. Replace
the original amd64 and i386 headers with stubs.

Rename (AMD64|I386)_BUS_SPACE_* to X86_BUS_SPACE_* everywhere.

6e3faf1602 Revert r216134. This checkin broke platforms where bus_space are macros:
they need to be a single statement, and do { } while (0) doesn't work in this
situation so revert until a solution can be devised.

dc1c4b9270 Disallow passing in a count of zero bytes to the bus_space(9) functions.
Passing a count of zero on i386 and amd64 for [I386|AMD64]_BUS_SPACE_MEM
causes a crash/hang since the 'loop' instruction decrements the counter
before checking if it's zero.

8d191fa363 Rename BUS_SPACE_IO and BUS_SPACE_MEM defines to BUS_SPACE_TAG_IO and
BUS_SPACE_TAG_MEM respectively to avoid conflict with nexus.c.

909db6af61 - Add the i386_memio_map_load() function to load I/O address table.
- Add the bus_space_compare macro for bus_space consistency.
- Switch using the bus_space_map_load() in isa_load_resourcev().

b8ebcde152 Add i386_memio_compare() to compare two resources.
It's used by uart(4) in the future.

e16c3e24aa There's no need to include all the detauls of struct bus_space_{tag,handle}
in _bus.h when the typedef of the struct pointer will do.

8c509864f2 Unbreak the pc98 build by including enough information in the _bus.h
for _bus.h to compile.

b1662f9d0f Break out the definition of bus_space_{tag,handle}_t and a few other types
into _bus.h to help with name space polution from including all of bus.h.
In a few days, I'll commit changes to the MI code to take advantage of thse
sepration (after I've made sure that these changes don't break anything in
the main tree, I've tested in my trees, but you never know...).

b8c5a800b0 With pc98/include, we can have pc98 and i386 specific bus space
implementations in their own files named $MACHINE/include/bus.h.  Copy
the contents appropriately.

35414c8894 Add reach-over include files to read i386/foo.h. In time, the pc98
specific code will migrate to these files to augment or replace the
version in i386/include and/or i386/linux.  This should, in the
fullness of time, allow many of the #ifdef PC98 in the tree.

# These files are in the public domain because there is insufficient
