gst/gstpipeline.c: Fix element details.

Browse source 
Original commit message from CVS:
2005-03-01  Andy Wingo  <wingo@pobox.com>

* gst/gstpipeline.c: Fix element details.
(gst_pipeline_set_property, gst_pipeline_get_property): Lock
around the whole get/set properties.

* gst/gstpad.c (gst_real_pad_set_property): Add a FIXME, the
::active property doesn't make sense any more.
(gst_pad_set_active): Check to see if the pad has the right
functions to be activated in this mode.
(gst_pad_event_default): Handle EOS specially, pausing the task on
the pad if necessary.

* gst/gstbin.c: Adapt callers of gst_iterator_foreach and
gst_iterator_filter to new argument order.

* gst/gstiterator.c (gst_iterator_find_custom)
(gst_iterator_foreach): Implement on top of gst_iterator_fold
instead of using the filter_next internals. A bit cleaner this
way.

* gst/gstiterator.h:
(gst_iterator_filter, gst_iterator_find_custom): Switch the
argument order so user_data is last.
(gst_iterator_foreach): Return the GstIteratorResult so the caller
knows if all elements were called, or if an error or resync
happened.
(gst_iterator_fold): New procedure.

* check/Makefile.am (TESTS):
* check/gst/gstiterator.c: New test suite for GstIterator. Checks
that iterating through a list hits all members in order, that
resync works correctly, and that fold works.

* gst/base/gstbasesink.c (gst_basesink_event): Fix Waymans bug.
