To manage dependency nicely.

When a module A dpend on B, you write "define A: B", where B has to be
already "define"'ed in the current syntax.  We're managing such
ordering "by hand" in sys/conf/files.  By splitting files & use
"include", we don't need to manage such a mess by hand.  David Holland
already understood this:

        http://mail-index.netbsd.org/tech-kern/2010/03/11/msg007633.html

So we have already agreed that split has "some" benefit.  The point
is, my split+include way doesn't need any syntax change.

I'm not saying changing syntax is bad.  My complaint is that David
Holland is suggesting things without understanding the existing
syntax.  I spent a whole weekend to read sys/conf/files, ioconf.c, and
module stubs in sys/dev/usb/uaudio.c.  I wasted a whole weekend.  I've
been wasting more time to convince David Holland who has never
bothered to understand the existing syntax.
