As this is unreleased development software anyway, I put it in (trusting
that the assignment will follow up).  I did some mild style corrections and
language fixing, and made all globals in slab.c static.

There are some internal names that are prefixed by hurd_ or __hurd_.  This
is not strictly necessary, but it's ok if you want to keep it that way.

One question I have: Why are slab spaces themselves managed with a slab? 
This makes sense to me if the slab allocator is the only one, but here the
default allocator is malloc, and the slab allocator is used for many objects
of the same type.  I don't think we will have lots and lots of slab spaces
dynamically created, so I think that just using malloc to allocate slab
spaces would be fine.  Of course, who knows what will happen.  We might find
lots of places to use such slab spaces, even dynamically, but I am not sure.

Thanks!
Marcus
