if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

NOTE: We must put ed_probe_SIC() function into if_ed_isa.c because
this is a bus dependent code. But the ed driver code is not
separated explicitly whether it is bus dependent or independent
now.

completenss. The pessimization is tiny compared with i/o port slowness
except on very old machines, but code that used signed short types for
i/o ports was unpessimized long ago, and the macro that detected it
recently started working for u_short types too. Use of bus space
should have made this moot long ago.

- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)
where physical addresses larger than virtual addresses, such as i386s
with PAE.
- Use this to represent physical addresses in the MI vm system and in the
i386 pmap code. This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
detection code, and due to kvtop returning vm_paddr_t instead of u_long.
Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

o Move the ax88190 code to its own function.
o Move all device_method_t, driver_t and DRIVER_MODULE definitions to the
end of files.
o Wrap a few lines > 80 characters.
o Use the same devclass for all ed drivers. This allows machines with
multiple types of cards to have their cards numbered correctly. Before,
you could wind up with two ed0's.
o Protect if_edvar.h from multiple includes because I was there.
