SBUS: Add an async request to retrieve the caller ID Adds an async request sbus_get_sender_id_{send,recv} that allows retrieval of UID based on "sender" as returned by dbus_message_get_sender(). The UID is an int64_t to be able to use "-1" to as a fallback value for uknown or error cases. The unit test is added as a standalone one, not part of the sbus_tests because the request, and by extension the unit test relies on being connected to the system bus, which is very unlikely to work in a build system.
