Original commit message from CVS: * gst/adder/gstadder.c: (gst_adder_get_type): Make it easier to copy&paste * gst/volume/Makefile.am: * gst/volume/gstvolume.c: (volume_update_real_volume), (gst_volume_set_volume), (gst_volume_set_mute), (gst_volume_class_init), (volume_process_int16), (volume_set_caps), (volume_transform_ip), (volume_update_mute), (volume_update_volume): * gst/volume/gstvolume.h: Add own debug category, move duplicate code to helper function, fix property texts, add more comments and prepare ffor liboil-goodness * tests/check/Makefile.am: * tests/check/elements/volume.c: (GST_START_TEST), (volume_suite): add test for mute and passtrough case, be a bit more verbose to track failure * tests/check/generic/states.c: (GST_START_TEST): catch elements that fail to instantiate
