* GstGlobalDeviceMonitor was renamed to GstDeviceMonitor * Expand GST_MESSAGE_DEVICE to the full enum value names * Correct the incorrect references to the GstDeviceProvider interfaces * Describe caps arguments for gstcheck interface * Add missing docs for GstNetAddressMeta and its add function * Add docs for toc helper macros * Avoid refering to GstValueList type as done elsewhere Fixes https://bugzilla.gnome.org/show_bug.cgi?id=732786
