Completely rework IP configuration in the daemon. Use NML3Cfg as layer 3 manager for the IP configuration of an interface. Use NML3ConfigData as pieces of configuration that the various components collect and configure. NMDevice is managing most of the IP configuration at a higher level, that is, it starts DHCP and other IP methods. Rework the state handling there. This is a huge rework of how NetworkManager daemon handles IP configuration. Some fallout is to be expected. It appears the patch deletes many lines of code. That is not accurate, because you also have to count the files `src/core/nm-l3*`, which were unused previously. Co-authored-by: Beniamino Galvani <bgalvani@redhat.com>
