Original commit message from CVS: Mega update of INFO, DEBUG, and ERROR subsystems, renamed with GST_ prefix. GST_DEBUG now takes a category parameter, which is the same as GST_INFO system. They are now called GST_CAT_*. All the GST_DEBUGs are set to 0 for now, we need to go and fix all these eventually.
