This means we no longer accept any iolist in some of the functions,
but we might bring it back later.
There is also a new function, geef_ref:create_symbolic() to create
symbolic references, since we can no longer differentiate between a
name and an OID.
This makes it useful for users of the bindings. The naming is the same
as the module to allow elixir to treat the records in much the same
way as its native module/record hybrid.
