       this dict's (otherwise).
       (ctf_try_lookup_indexed): Allow the symname to be passed in.
       (ctf_lookup_by_symbol): Turn into a wrapper around...
       (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
       using ctf_lookup_symbol_idx in non-writable dicts.  Special-case

       lookup-by-name support, with dicts of successful lookups cached in
       ctfi_symnamedicts.  Refactor the caching code a bit.

       broken.
