Fix a segfault in handle_interface: if we're adding an interface that
we already knew about (in particular due to a udev event), then
calling init_state/start_interface on ifp is bad because we later free
ifp. This leads to messages like:
dhcpcd[1342]: eth0: IAID conflicts with one assigned to eth0
and then a crash:
Invalid read of size 8

So ignore interfaces that we already know about.

Fix segfault when reloading the configuration: free_globals() left the
ifac/ifdc variables at -1 instead of 0, causing a crash later in
splitv().
