syslogd: make -d accept an optional argument

Make it possible to specify the debug message categories with an
optional numeric argument. You'll have to read the fine source to
find out what they are. The number can be specified as the usual
decimal, hex (0x), or octal (0) literal with an optional ~negation.

Since syslogd uses getopt(3), not getopt_long(3), do a bit of
gymnastics so that both -d42 and -d 42 are accepted (I'm not inventing
long names for all the existing options just to support an optional
argument to -d).

-d without an argument still uses the old D_DEFAULT selection just in
case someone really relies on that. You can disable all debug
messages with -d0 but still get syslogd not daemonized.

syslogd: allow the reporting of buffer overflows to be disabled.

This generally isn't a good thing, nothing should be discard silently.
However, for systems that don't want big syslogd buffers or are too slow
to log effectively this reporting can now be disabled.

Use looked up remote host for remote message without a hostname

An incoming remote message may not necessarily have a hostname
between the timestamp and the message. The the source of the remote
sender is already looked up so use that hostname/IP address rather
than the local hostname.
