Log Message:
Pullups approved by thorpej --
Add byte-swap and stride options to bus_space.  Allocate as normal, then
call mac68k_bus_space_handle_swapped() or mac68k_bus_space_handle_set_stride().
Stride is untested.  Swapped code works for SMC ethernet.

Add bus_space_*_stream_N functions to bus_space.

Add a DIAGNOSTIC panic if (count-using) bus_space macros are called with
a count of zero.  Some drivers do this accidentally and some bus_space
implementations will fail if count is passed as zero (they are set up in
a do-{}-while structure).

There were some bogus assumptions about bus_space_handle_t and some
function calls that didn't match prototypes--fix those here, too.
