r2542: I really don't like the 'substitute' code, and I particularly don't

like it in the mainline code (outside the smb.conf magic).

We will need to have a more useful 'helper' routine for this, but for
now we at least get a reliable IP address.

Also remove the unused 'socket' structure in the smb server - it seems
to have been replaced by the socket library.
