This allows to add pad templates and set metadata in class_init instead of base_init. base_init is a concept that is not supported by almost all languages and copying the templates/metadata for subclasses is the more intuitive way of doing things. Subclasses can override pad templates of parent classes by adding a new template with the same now. Also gst_element_class_add_pad_template() now takes ownership of the pad template, which was assumed by all code before anyway. Fixes bug #491501.
