Original commit message from CVS: GST_DEBUG reorganization This is a big diff (ca 450k), containing loads of stuff: - gstinfo.[ch] complete rewrite - changing of all GST_DEBUG messages to reflect that change - reorganization of subsystem disabling - addition of gstconfig.h.in so we can track the disablings - <gst/gst.h> does not include <unistd.h> and <config.h> anymore - documentation updated for gstinfo stuff (build the docs yourself to know what changed) - bugfixes for making of the docs (files from CVS are not deleted anymore - testsuite for debugging changes in testsuite/debug expect breakage
