... and G_TYPE_INSTANCE_GET_PRIVATE() g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were deprecated in GLib 2.58. Instead, use G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined foo_get_instance_private() functions, all of which are available in the GLib versions we depend on. This commit only covers types registered using one of the G_DEFINE_FOO() macros (i.e., most types), but not types with a custom registration function, of which we still have a few -- GLib currently only provides a (non-deprecated) public API for adding a private struct using the G_DEFINE_FOO() macros. Note that this commit was 99% auto-generated (because I'm not *that* crazy :), so if there are any style mismatches... we'll have to live with them for now.
