ctrl: Allow installation of additional node lookup helpers

The existing code assumes that the main application knows about all
control command nodes and can thus present one lookup function.

As libraries are getting their own control interface handling, this
is too restrictive, and we need a way how library code can dynamically
register more node lookup helpers.   We can now do this by means of a
ctrl_lookup_register() function.
