Original commit message from CVS:
* gst/auparse/Makefile.am:
* gst/auparse/gstauparse.c: (gst_auparse_class_init),
(gst_auparse_init), (gst_auparse_dispose), (gst_auparse_chain),
(gst_auparse_change_state):
* gst/auparse/gstauparse.h:
Partially fix #161712. playbin still doesn't work on these files,
(on the bug report, Andy says we aren't typefinding it for some
reason?) but at least auparse isn't totally busted like it was before.
