Merged from sys/isa/{fd.c,fdreg.h} revisions 1.222 and 1.15, respectively.

- Refine pc98 supports.
- Use bus_space stuff.
- Rename FDO_* -> FDC_* (obtained from NetBSD/pc98)

Move out the files from src/sys/isa/ic/ to src/sys/dev/ic/, so they
can be made userland-visible as <dev/ic/...>. Also, those files are
not supposed to contain any bus-specific details at all, so placing
them under .../isa/ has been a misnomer from the beginning.

The files in src/sys/dev/ic/ have been repo-copied from their old
location (this commit is a forced null commit there to record this
message).

Merge from sys/isa/fd.c revision from 1.171 to 1.176 and sys/isa/fdreg.h
revision 1.13.

$Id$ -> $FreeBSD$

Fixed locations of include files.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

More merge. Change "pc98" to "isa" in a few places. Misc. cleanup.
Add some more devices to userconfig.c.
