API: Add GST_IS_PARAM_SPEC_MINI_OBJECT, GST_PARAM_SPEC_MINI_OBJECT
Original commit message from CVS: * gst/gstminiobject.c: (gst_value_dup_mini_object), (gst_param_spec_mini_object): * gst/gstminiobject.h: * win32/common/libgstreamer.def: * docs/gst/gstreamer-sections.txt: API: Add GST_IS_PARAM_SPEC_MINI_OBJECT, GST_PARAM_SPEC_MINI_OBJECT GST_TYPE_PARAM_MINI_OBJECT and gst_value_dup_mini_object. Also move GstParamSpecMiniObject into a public header for this. This make GstMiniObject a bit more consistent with GObject and makes it possible to extend the param specs. gst_value_dup_mini_object is mainly useful for set_property methods. Fixes bug #523798. * tools/gst-inspect.c: (print_element_properties_info): Print something useful for GstMiniObject properties and not just "unknown type".
