ip[46]-config: reorder fields in private struct and use bool bitfield

Browse source 
bool:1 bitfields allow for tighter packing and are guaranteed to be
strictly 0 or 1 (contrary to gboolean's typedef for int). Not that it
matters too much, but it's favorable.

Especially, because each device has several of these ip-config instances,
we might save a few bytes for no(?) downsides.
