* Replace glib GError with GAutoPtr<GError> in ChipDeviceScanner

* Replace glib GError with GAutoPtr<GError> in Bluez helper

* Replace glib GError with GAutoPtr<GError> in ConnectivityMangaerImpl

* Replace glib GVariant with GAutoPtr<GVariant> in ConnectivityManagerImpl

* Replace glib GVariant with GAutoPtr<GVariant> in Bluez helper

* Replace glib and char with GAutoPtr<char> in Bluez helper

* Replace glib and GVariantDict with GAutoPtr<GVariantDict> in Bluez helper - review

* Fix badly used MakeUniquePointerReceiver

* Review changes

* Replace g_variant_dict_lookup_value to g_variant_lookup_value in src/platform/Linux/bluez/Helper.cpp
* Add template <> struct GAutoPtrDeleter<const char *>
* Convert keyMgmts to GAutoPtr in src/platform/Linux/ConnectivityManagerImpl.cpp
* Revert in ConnectionDataBundle GVariant convert to GAutoPtr

* Review update - remove GVariantDict
