It can handled simillar to uri-handler iface in registry. Instead of
GstElementFactory (in the uri-handler case) we would extend GstPluginFeature to
have a GstStructure *extra_data; and add _set/get functions.

Plugins would need to access or produce this data in plugin_init().

GstPluginFeature *my_feature;
GstStructure *data;

/* getting the feature from the plugin itself would be useful */
my_feature = gst_registry_lookup_feature(
  gst_registry_get_default(), "my-plugin");

data =  gst_plugin_feature_get_extra_data (my_feature);
if(!data) {
  /* we are running in registry update */
  data = gather_data(...);
  gst_plugin_feature_set_extra_data (my_feature, data);
}

/* use the cache data */
register_elements (plugin, data);
