interfaces: static handling is the same as dynamic
interfaces: static handling is the same as dynamic

Tiptoeing around interface_configure() when the resulting
work is the same is counter-intuitive and the static ARP
case probably has some more side effects since we do not
check for static ARP flag?!

filter_configure() can take a long time.  Skip alias stuff.
