Original commit message from CVS: * Makefile.am: Add check-exports target and run it as part of 'make check' (see #499140 and #493983). * gst/gst_private.h: * gst/gstelementfactory.h: * gst/gstghostpad.c: (gst_proxy_pad_class_init): * gst/gstinfo.c: (_priv_gst_in_valgrind), (_gst_debug_init), (_priv_gst_in_valgrind): * gst/gstinfo.h: (GstLogFunction): * gst/gsttypefind.c: (type_find_debug), (GST_CAT_DEFAULT), (gst_type_find_register): * gst/gsttypefindfactory.c: (type_find_debug), (GST_CAT_DEFAULT), (gst_type_find_factory_get_type): * libs/gst/controller/gstcontroller.c: (GST_CAT_DEFAULT), (GST_CAT_DEFAULT), (parent_class), (priv_gst_controller_key), (gst_controller_new_valist), (gst_controller_new_list), (_gst_controller_dispose), (_gst_controller_class_init): * libs/gst/controller/gstcontrolsource.c: (GST_CAT_DEFAULT): * libs/gst/controller/gsthelper.c: (GST_CAT_DEFAULT), (GST_CAT_DEFAULT), (gst_object_uncontrol_properties), (gst_object_get_controller), (gst_object_set_controller), (gst_object_suggest_next_sync), (gst_object_sync_values), (gst_object_set_control_source), (gst_object_get_control_source), (gst_object_get_value_arrays), (gst_object_get_value_array), (gst_object_get_control_rate), (gst_object_set_control_rate): * libs/gst/controller/gstinterpolation.c: (GST_CAT_DEFAULT): * libs/gst/controller/lib.c: (GST_CAT_DEFAULT): Make some functions that should be static static; rename some private symbols so that they don't get exported; add some FIXME comments so we can move accidentally exported functions into our private section in 0.11. * win32/common/libgstreamer.def: Add gst_utils_get_timestamp().
