Adds a padtemplate to an element class. This is mainly used in the _class_init
functions of classes. If a pad template with the same name as an already
existing one is added the old one is replaced by the new one.
templ's reference count will be incremented, and any floating
reference will be removed (see gst_object_ref_sink())
