(gst_mms_base_init), (gst_mms_class_init), (gst_mms_init),
(gst_mms_finalize), (gst_mms_create), (gst_mms_start),
(gst_mms_set_property), (gst_mms_get_property),
(gst_mms_uri_get_uri):
* ext/libmms/gstmms.h:
Some clean-ups; more debug output; use blocksize property
of GstBaseSrc instead of re-registering our own; make debug
category actually be used.
