Manual updates for MR#1622

* [`gdk_pixbuf_format_get_extensions`]
  > The array is `NULL`-terminated.
* [`gdk_pixbuf_format_get_mime_types`]
  > The array is `NULL`-terminated.
* [`g_dbus_proxy_get_cached_property_names`]
  > [...] `NULL` if the value is not in the cache.
* [`g_file_info_list_attributes`]
  > [...] `NULL` on error.
  ==> but NULL as an error is only used for the case where `FileInfo` is NULL, which is not possible in Rust.
* [`g_tls_certificate_get_dns_names`]
  > [...] `NULL` if it’s not available.
* [`g_tls_certificate_get_ip_addresses`]
  > [...] `NULL` if it’s not available.
* [`pango_font_get_languages`]
  > The array is `NULL`-terminated.
* [`pango_font_face_list_sizes`]
  > This is only applicable to bitmap fonts. For scalable fonts, stores `NULL` at the location pointed to by sizes and `0` at the location pointed to by `n_sizes`.
* [`pango_language_get_preferred`](https://docs.gtk.org/Pango/type_func.Language.get_preferred.html)
  > The array is `NULL`-terminated.
