libnm-core: merge NMSetting*Error into NMConnectionError Each setting type was defining its own error type, but most of them had exactly the same three errors ("unknown", "missing property", and "invalid property"), and none of the other values was of much use programmatically anyway. So, this commit merges NMSettingError, NMSettingAdslError, etc, all into NMConnectionError. (The reason for merging into NMConnectionError rather than NMSettingError is that we also already have "NMSettingsError", for errors related to the settings service, so "NMConnectionError" is a less-confusable name for settings/connection errors than "NMSettingError".) Also, make sure that all of the affected error messages are localized, and (where appropriate) prefix them with the relevant property name. Renamed error codes: NM_SETTING_ERROR_PROPERTY_NOT_FOUND -> NM_CONNECTION_ERROR_PROPERTY_NOT_FOUND NM_SETTING_ERROR_PROPERTY_NOT_SECRET -> NM_CONNECTION_ERROR_PROPERTY_NOT_SECRET Remapped error codes: NM_SETTING_*_ERROR_MISSING_PROPERTY -> NM_CONNECTION_ERROR_MISSING_PROPERTY NM_SETTING_*_ERROR_INVALID_PROPERTY -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_ERROR_PROPERTY_TYPE_MISMATCH -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_BLUETOOTH_ERROR_TYPE_SETTING_NOT_FOUND -> NM_CONNECTION_ERROR_INVALID_SETTING NM_SETTING_BOND_ERROR_INVALID_OPTION -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_BOND_ERROR_MISSING_OPTION -> NM_CONNECTION_ERROR_MISSING_PROPERTY NM_SETTING_CONNECTION_ERROR_TYPE_SETTING_NOT_FOUND -> NM_CONNECTION_ERROR_MISSING_SETTING NM_SETTING_CONNECTION_ERROR_SLAVE_SETTING_NOT_FOUND -> NM_CONNECTION_ERROR_MISSING_SETTING NM_SETTING_IP4_CONFIG_ERROR_NOT_ALLOWED_FOR_METHOD -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_IP6_CONFIG_ERROR_NOT_ALLOWED_FOR_METHOD -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_VLAN_ERROR_INVALID_PARENT -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_WIRELESS_SECURITY_ERROR_MISSING_802_1X_SETTING -> NM_CONNECTION_ERROR_MISSING_SETTING NM_SETTING_WIRELESS_SECURITY_ERROR_LEAP_REQUIRES_802_1X -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_WIRELESS_SECURITY_ERROR_LEAP_REQUIRES_USERNAME -> NM_CONNECTION_ERROR_MISSING_PROPERTY NM_SETTING_WIRELESS_SECURITY_ERROR_SHARED_KEY_REQUIRES_WEP -> NM_CONNECTION_ERROR_INVALID_PROPERTY NM_SETTING_WIRELESS_ERROR_CHANNEL_REQUIRES_BAND -> NM_CONNECTION_ERROR_MISSING_PROPERTY Dropped error codes (were previously defined but unused): NM_SETTING_CDMA_ERROR_MISSING_SERIAL_SETTING NM_SETTING_CONNECTION_ERROR_IP_CONFIG_NOT_ALLOWED NM_SETTING_GSM_ERROR_MISSING_SERIAL_SETTING NM_SETTING_PPP_ERROR_REQUIRE_MPPE_NOT_ALLOWED NM_SETTING_PPPOE_ERROR_MISSING_PPP_SETTING NM_SETTING_SERIAL_ERROR_MISSING_PPP_SETTING NM_SETTING_WIRELESS_ERROR_MISSING_SECURITY_SETTING

libnm: rework setting metadata for property handling 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.
