Ticket #931. Check that directory exist before trying to tar up. Do this for rrd and dhcpleases scripts used during shutdown.

Mark subsystem as dirty.

Do not use mwexec when unlink can be used and is faster. This also avoids errors on log from rm(1).

Do not try to update dyndns for an interface that no ip can be determined, since it will not suceed. Reported-by: http://forum.pfsense.org/index.php/topic,28750.0.html

Fix checking the status of gateways. Typos and unset variables! Spotted-by: Mark Huijgen

Fix intended behaviour when the default gateway changes interface.

This breaks the code because the ASSUMPTION is to reload the gateway interface that was a defaultgw previously and not the interface that just became defaultgw. Mostly for dynamic connections like dhcp/ppp*
