libio preparation for file systems

[Joel Sherrill]

Hi,

I am beginning to look at adding the infrastructure for
a more robust name space in RTEMS.  libio was orignally
designed to map device names into major/minor pairs and
pass IO request through to device drivers.  Since that
time, it has been augmented to support sockets.

I would like to start getting the infrastructure in place
to be able to mount file systems, walk directory trees
of "/dev", etc.  Essentially have a better "logical
file system."

Right now, I am looking at the way this is done in various
free UNIces (Linux and NetBSD).  I would like suggestions
on what capabilities you folks would like to see in
this area.  If you have ideas about possible implementations 
we could look at.

I hope this opens a discussion.

Thanks.
