Original commit message from CVS: * check/Makefile.am: * check/generic/states.c: * gst/Makefile.am: * gst/gst.c: * gst/gst.h: * gst/gst_private.h: * gst/gstelementfactory.c: * gst/gstindex.c: * gst/gstinfo.c: * gst/gstplugin.c: * gst/gstplugin.h: * gst/gstpluginfeature.c: * gst/gstpluginfeature.h: * gst/gstregistry.c: * gst/gstregistry.h: * gst/gstregistrypool.c: remove * gst/gstregistrypool.h: remove * gst/gsttypefind.c: * gst/gsttypefindfactory.c: * gst/gsturi.c: * tools/Makefile.am: * tools/gst-compprep.c: * tools/gst-inspect.c: * tools/gst-register.c: remove * tools/gst-xmlinspect.c: Registry rewrite. Changes registry from being a file created by a tool into a simple cache file created automatically by libgstreamer. Removed gst-register (because it's no longer needed). Remove registry pools, because we only have one registry implementation (XML). Fix up other subsystems as necessary.
