Original commit message from CVS: Totally rewritten registry handling. - move the registry save/load code into a gstregistry subclass, this will make it possible to use other registries (flat file, web based, RDBMS type, etc..) - a simple GMarkup xml registry is implemented - use standard statically linked plugins for core elements. - GstPlugin has a very well defined set of functions now A little bytestream hack.. Added more info to -inspect. Some more debugging info for clocking. Small cleanups I use ./gst-register --gst-plugin-path=/opt/src/sourceforge/gst-plugins/gst-libs:/opt/src/sourceforge/gst-plugins/ to register core and gst-plugins now.
