Description

A number of Flight APIs use the convention of returning a Status and filling an actual return value in a pointer-out (T*) parameter. They should be migrated to returning Result<T> instead, together with a deprecation notice on the legacy API.

Examples are BasicAuth::Serialize, BasicAuth::Deserialize, Location::Parse, etc.
