expansion.

MFp4 (imp_freebsd branch): snapshot of devd work:

2002-12-07T08:04:36+00:00

o create data structures based on the parsed file now.
o Still need to rewrite main loop and add regex (still uses hard coded
  devd-generic)
o minor man page updates.

arbitrary commands when devices come and go in the device tree (which is
different than the /dev directory).

This is an initial version.  Much of the planned power isn't here.
Instead of doing the full matching, we always run /etc/devd-generic.
/etc/devd.generic will go away at some point, I think.

I'm committing it in this early state so I can start getting feedback
from early adapters.
