sbus: Rework sbus to use interface metadata and vtables

Previous commits added support for interface metadata and
handler vtables. This commit ports sbus_dbus_connection to
use them.

Port the internal uses of dbus to use the new scheme in a
very minimal way. Further cleanup is possible here.

This commit provides basic definitions of the internal
dbus interfaces. The interfaces aren't fully defined, as the
handlers will continue to unpack manually, and often overload
DBus methods with different arguments (which is rather
unorthodox, but not the end of the world).
