Original commit message from CVS:
2004-01-13  Benjamin Otte  <in7y118@public.uni-hamburg.de>

* gst/gstclock.c: (gst_clock_class_init), (gst_clock_init),
(gst_clock_set_speed), (gst_clock_set_active),
(gst_clock_is_active), (gst_clock_reset),
(gst_clock_handle_discont):
* gst/gstclock.h:
deprecate old interface and disable functions that aren't in use
anymore.
* gst/gstelement.h:
* gst/gstelement.c: (gst_element_get_time), (gst_element_wait),
(gst_element_set_time), (gst_element_adjust_time):
add concept of "element time" and functions to get/set this time.
* gst/gstelement.c: (gst_element_change_state):
update element time correctly.
* gst/gstelement.c: (gst_element_get_compatible_pad_filtered):
This is a debug message, not a g_critical.
* gst/gstpad.c: (gst_pad_event_default):
handle discontinuous events right with element time.
* gst/gstscheduler.c: (gst_scheduler_state_transition):
update to clocking fixes.
set clocks on elements in READY=>PAUSED. The old behaviour caused
a wrong element time on the first element that started playing.
* gst/schedulers/gstbasicscheduler.c:
(gst_basic_scheduler_class_init):
* gst/schedulers/gstoptimalscheduler.c:
(gst_opt_scheduler_class_init):
remove code that just implements the default behaviour.
* gst/elements/gstfakesink.c: (gst_fakesink_chain):
update to use new clocking functions
* testsuite/clock/clock1.c: (gst_clock_debug), (main):
* testsuite/clock/clock2.c: (gst_clock_debug), (main):
update to test new element time.
* gst/autoplug/gstspideridentity.c: (gst_spider_identity_getcaps):
use _get_allowed_caps instead of _get_caps. This catches filtered
caps correctly.
* testsuite/debug/commandline.c:
update for new GST_DEBUG syntax.
* testsuite/threads/Makefile.am:
disable a test that only works sometimes.
