NMSetting internally already tracked a list of all proper GObject properties and D-Bus-only properties. Rework the tracking of the list, so that: - instead of attaching the data to the GType of the setting via g_type_set_qdata(), it is tracked in a static array indexed by NMMetaSettingType. This allows to find the setting-data by simple pointer arithmetic, instead of taking a look and iterating (like g_type_set_qdata() does). Note, that this is still thread safe, because the static table entry is initialized in the class-init function with _nm_setting_class_commit(). And it only accessed by following a NMSettingClass instance, thus the class constructor already ran (maybe not for all setting classes, but for the particular one that we look up). I think this makes initialization of the metadata simpler to understand. Previously, in a first phase each class would attach the metadata to the GType as setting_property_overrides_quark(). Then during nm_setting_class_ensure_properties() it would merge them and set as setting_properties_quark(). Now, during the first phase, we only incrementally build a properties_override GArray, which we finally hand over during nm_setting_class_commit(). - sort the property infos by name and do binary search. Also expose this meta data types as internal API in nm-setting-private.h. While not accessed yet, it can prove beneficial, to have direct (internal) access to these structures. Also, rename NMSettingProperty to NMSettInfoProperty to use a distinct naming scheme. We already have 40+ subclasses of NMSetting that are called NMSetting*. Likewise, NMMetaSetting* is heavily used already. So, choose a new, distinct name.
