/dev patch

I've had this patch kicking about for a while and I was going to merge it
with the next /proc patch but I remembered that separate patches are
generally preferred on this list and the /proc stuff has been delayed
This patch adds support for a virtual /dev which just lists the devices that
cygwin currently supports. The /dev prefix is read from the mount_table, as
is now the /proc prefix. I haven't added a mechanism to read these from the
registry or allow them to be changed using mount since most programs expect
to find these directories at a fixed location.
