tests/complexity.c: Adjust to lack of gst_bin_iterate, boolean link return values.

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

* tests/complexity.c: Adjust to lack of gst_bin_iterate, boolean
link return values.

* gst/elements/gsttee.c, gst/elements/gsttee.h: I am the master of
do-nothing plugins! Fear the dev-zero!

* gst/elements/gstelements.c
* gst/elements/Makefile.am: Add tee back to gstelements.

* gst/gstutils.h
* gst/gstutils.c (gst_pad_proxy_getcaps, gst_pad_proxy_setcaps):
Resurrect from the dead. Use gst_iterator_fold to be threadsafe.

* gst/gstiterator.h (GstIteratorFoldFunction): Return a bool.

* gst/gstiterator.c (gst_iterator_fold): Only continue folding as
long as the fold function returns TRUE. Add a bunch o docs.
(gst_iterator_foreach): Add docs about when the iterator will be
freed.
(gst_iterator_find_custom): Make more efficient because of the
bool-return-value thing.

* check/gst/gstiterator.c (add_fold_func): Adapt to new
fold-funcs-returning-bool policy.

* gst/gstutils.h:
* gst/gstutils.c (gst_element_link, gst_element_link_many)
(gst_element_link_filtered, gst_element_link_pads)
(gst_element_link_pads_filtered): It seems Wim changed the return
type to booleans internally. Assume he knows what he's doing and
change the prototypes as well.

* tests/Makefile.am, tests/complexity.c:
* tests/complexity.gnuplot, tests/bench-complexity.scm: Merge in
complexity tests from HEAD.
* 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.
