fs newcell mostly-broken

[Nickolai Zeldovich]

At the moment, "fs newcell" in arla sets the "name" field of the
cell_db_entry's to NULL.  This causes updatehosts() to crash when
trying to strcmp the host fields in host_sort().

The patch below changes host_sort() to compare based on IP address
rather than hostname -- the actual ordering doesn't really matter,
as far as I can tell.
