some patches

[Nickolai Zeldovich]

Just a couple of patches I've applied here -- first one adds "df"
as an alias for "diskfree" to fs, which emulates the behavior of
Transarc's fs. The second ensures that all mandatory arguments are
actually filled (otherwise "pts createu" creates a user using some
random stack garbage).

The third patch fixes configuration on FreeBSD 4.2-RELEASE; since
vnode_if.h is auto-generated, there is no sys/vnode_if.h, and
sys/vnode.h has an #include "vnode_if.h". This shouldn't break
NetBSD either, which has an #include <sys/vnode_if.h> in
sys/vnode.h.
