Rework NMSetting structures: Move each setting to it's own file.
        Convert to GObject. Remove home grown setting types and use
GTypes.
        Use GObject property introspection for hash conversion,
enumerating
        properties, etc.

        * libnm-util/nm-setting-connection.[ch]
        * libnm-util/nm-setting-ip4-config.[ch]
        * libnm-util/nm-setting-ppp.[ch]
        * libnm-util/nm-setting-vpn.[ch]
        * libnm-util/nm-setting-vpn-properties.[ch]
        * libnm-util/nm-setting-wired.[ch]
        * libnm-util/nm-setting-wireless.[ch]
        * libnm-util/nm-setting-wireless-security.[ch]

        New files, each containing a setting.

        * libnm-util/nm-setting-template.[ch]: A template for creating
        * new
        settings. To use it, just replace 'template' with the new
setting
        name, and you're half-way done.

        * libnm-util/nm-setting.c: Convert to GObject and use GObject
        introspection instead of internal types and tables.

        * libnm-util/nm-connection.c: Adapt the new NMSetting work.

        * libnm-util/nm-param-spec-specialized.[ch]: Implement. Handles
        GValue types defined by dbus-glib for composed types like
collections,
        structures and maps.

        * src/*: The API of NMSetting and NMConnection changed a bit:
        * Getting
        a setting from connection takes the setting type now. Also,
since
        the settings are in multiple files, include relevant settings.
