gst/matroska/: Some cleanups, refactoring and minor enhancements in caps handling.
Original commit message from CVS: * gst/matroska/matroska-demux.c: (gst_matroska_demux_video_caps): * gst/matroska/matroska-mux.c: (gst_matroska_mux_video_pad_setcaps): Some cleanups, refactoring and minor enhancements in caps handling. * gst/matroska/matroska-mux.c: (gst_matroska_mux_class_init), (gst_matroska_mux_init), (gst_matroska_pad_reset), (gst_matroska_pad_free), (gst_matroska_mux_reset), (gst_matroska_mux_video_pad_setcaps), (gst_matroska_mux_request_new_pad): * tests/check/elements/matroskamux.c: (teardown_src_pad): Only remove, release or reset what is appropriate upon state change.
