<id>urn:sha1:e5b33b02f5a95ab4b18978f78032dd8f9c1cca36</id>
<content type='text'>
Migrate the string option/struct fields in the api headers to std::string
and propagate the change through the native client attribute helpers,
list_operations, operation cache and the api-bound driver accessors. A cold
to_lower boundary keeps a TString cast.
