I can change that then. so within ConnMan and oFono we make a difference between public symbols that are reachable from within plugins and other which are not. In general btd_ should be public symbols available to plugins and __btd_ for internal symbols that are no available to plugins. For builtin plugins that makes no difference of course, but this is not about internal builtin plugins. It is for protecting against external plugins to not allow access to internal details. That said, bluetoothd is not linked with the case to hide certain symbols anyway so that right now there is no real difference here.
