Original commit message from CVS: * gst/gst.c: (init_pre), (scan_and_update_registry), (ensure_current_registry_nonforking), (ensure_current_registry_forking), (ensure_current_registry), (init_post), (gst_debug_help), (gst_deinit): * gst/gst_private.h: * gst/gstregistry.c: (gst_registry_finalize), (gst_registry_remove_features_for_plugin_unlocked), (gst_registry_remove_plugin), (gst_registry_scan_path_level), (gst_registry_scan_path), (_priv_gst_registry_remove_cache_plugins), (_priv_gst_registry_cleanup): * gst/gstregistry.h: Re-commit the registry changes, along with an extra fix: When a cached plugin is encountered at a different file path, update the stored path in the registry cache so that the parent process knows where it actually is now when it re-reads the registry cache. Fixes the thing that broke distcheck with the previous commit. * tests/check/Makefile.am: Clean up files named 'core' too when running make clean. * tests/examples/manual/Makefile.am: Set up a registry path for running these tests, and clean it properly for distcheck.
