Now I have done almost work for new devsw in gehenna-devsw branch.
The changes will be merged into mainline after 1.6 is released.

By this changes, the device majors are listed up in majors.<arch>.
On the other hand, we have another majors list ``MAKEDEV'' in basesrc.
These two files are maintained by hands.

To make reflect reality to MAKEDEV easy,
I wrote one tiny awk script ``devmajors.awk'' which generates
a simple majors list ``MAKEDEV.majors'' and changed MAKEDEV use it.

The samples for i386 are available at:

Any comments/objections/improvements?
Or do you have better idea?
