gst/interleave/deinterleave.c: Add another example launch line.
Original commit message from CVS: * gst/interleave/deinterleave.c: Add another example launch line. * gst/interleave/interleave.c: (interleave_24), (gst_interleave_finalize), (gst_interleave_base_init), (gst_interleave_class_init), (gst_interleave_init), (gst_interleave_request_new_pad), (gst_interleave_release_pad), (gst_interleave_change_state), (__remove_channels), (__set_channels), (gst_interleave_sink_getcaps), (gst_interleave_set_process_function), (gst_interleave_sink_setcaps), (gst_interleave_sink_event), (gst_interleave_src_query_duration), (gst_interleave_src_query), (forward_event_func), (forward_event), (gst_interleave_src_event), (gst_interleave_collected): * gst/interleave/interleave.h: Major rewrite of interleave using GstCollectpads. This new version also supports almost all raw audio formats and has better caps negotiation. Fixes bug #506594. Also update docs and add some more examples. * tests/check/elements/interleave.c: (interleave_chain_func), (GST_START_TEST), (src_handoff_float32), (sink_handoff_float32), (interleave_suite): Add some more extensive unit tests for interleave.
