Avoid spurious local-port warnings

Browse Source 
Our old warn_nonlocal_client_ports() would give a bogus warning for
every nonlocal port every time it parsed any ports at all.  So if it
parsed a nonlocal socksport, it would complain that it had a nonlocal
socksport...and then turn around and complain about the nonlocal
socksport again, calling it a nonlocal transport or nonlocal dnsport,
if it had any of those.

Fixes bug 7836; bugfix on 0.2.3.3-alpha.

o Minor bugfixes:
- Avoid spurious warnings when configuring multiple client ports of
which only some are nonlocal. Previously, we had claimed that some
were nonlocal when in fact they weren't. Fixes bug 7836; bugfix on
0.2.3.3-alpha.
