Andy Wingo 9d1b5e07b3 check/pipelines/simple_launch_lines.c (run_pipeline): Check element_set_state's return val.
Original commit message from CVS:
2005-08-26  Andy Wingo  <wingo@pobox.com>

* check/pipelines/simple_launch_lines.c (run_pipeline): Check
element_set_state's return val.
(test_2_elements): Add test that's been disabled for months.

* gst/elements/gstfakesink.c: Cleanups. Add can-activate-push and
can-activate-pull properties.

* gst/elements/gstfakesrc.c: Cleanups. Add can-activate-push and
can-activate-pull properties. Implement is_seekable so fakesrc can
operate in pull mode.

* gst/base/gstbasesink.c (GstBaseSink): Remove has-loop, has-chain
properties.
(gst_base_sink_activate, gst_base_sink_activate_pull)
(gst_base_sink_activate_push): Make activation mode choosing work.
Cleanups.
(gst_base_sink_chain, gst_base_sink_loop): Assert activation mode
is right. Make pull mode work. Post an eos before pausing in pull
mode.
(gst_base_sink_change_state): Pay attention to the core's
change_state() return val.

* gst/base/gstbasesrc.c (GstBaseSrc): Remove has-loop,
has-getrange properties. Cleanups.

* gst/base/gstbasesrc.h (GstBaseSrc): Remove has_loop,
has_getrange and replace with can_activate_pull and
can_activate_push.

* gst/base/gstbasesink.h (GstBaseSink): Rearrange fields, add
locking comments. Remove has_loop, has_chain and replace with
can_activate_pull and can_activate_push.
