Dan Winship 3f30c6f1c2 libnm-core: extract NMSettingIPConfig superclass out of IP4, IP6 classes
Split a base NMSettingIPConfig class out of NMSettingIP4Config and
NMSettingIP6Config, and update things accordingly.

Further simplifications of now-redundant IPv4-vs-IPv6 code are
possible, and should happen in the future.

/**
* SECTION:nm-setting-ip6-config
* @short_description: Describes IPv6 addressing, routing, and name service properties
*
* The #NMSettingIP6Config object is a #NMSetting subclass that describes
* properties related to IPv6 addressing, routing, and Domain Name Service
*
* #NMSettingIP6Config has few properties or methods of its own; it inherits
* almost everything from #NMSettingIPConfig.
*
* NetworkManager supports 6 values for the #NMSettingIPConfig:method property
* for IPv6. If "auto" is specified then the appropriate automatic method (PPP,
* router advertisement, etc) is used for the device and most other properties
* can be left unset. To force the use of DHCP only, specify "dhcp"; this
* method is only valid for Ethernet- based hardware. If "link-local" is
* specified, then an IPv6 link-local address will be assigned to the interface.
* If "manual" is specified, static IP addressing is used and at least one IP
* address must be given in the "addresses" property. If "ignore" is specified,
* IPv6 configuration is not done. Note: the "shared" method is not yet
* supported.
