Original commit message from CVS: * gst/interleave/Makefile.am: * gst/interleave/deinterleave.c: (deinterleave_24), (gst_deinterleave_finalize), (gst_deinterleave_base_init), (gst_deinterleave_class_init), (gst_deinterleave_init), (gst_deinterleave_add_new_pads), (gst_deinterleave_set_pads_caps), (gst_deinterleave_set_process_function), (gst_deinterleave_sink_setcaps), (__remove_channels), (__set_channels), (gst_deinterleave_getcaps), (gst_deinterleave_process), (gst_deinterleave_chain), (gst_deinterleave_sink_activate_push): * gst/interleave/deinterleave.h: Add support for all raw audio formats and provide better negotiation if the caps are changing. Don't allow changes of the channel positions and set the position of the corresponding channel on the src pad caps. General cleanup and smaller bugfixes. * tests/check/elements/deinterleave.c: (float_buffer_check_probe): Check the channel positions on the output buffer caps.
