Introduce a version field to `struct xucred' in place of one of the

spares (the size of the field was changed from u_short to u_int to
reflect what it really ends up being).  Accordingly, change users of
xucred to set and check this field as appropriate.  In the kernel,
this is being done inside the new cru2x() routine which takes a
`struct ucred' and fills out a `struct xucred' according to the
former.  This also has the pleasant sideaffect of removing some
duplicate code.
