@brief Realise a Nix store path

Blocking, calls callback once for each realised output.

@note When working with expressions, consider using e.g. nix_string_realise to get the output. .drvPath may not be accurate or available in the future. See https://github.com/NixOS/nix/issues/6507

@param[out] context Optional, stores error information @param[in] store Nix Store reference @param[in] path Path to build @param[in] userdata data to pass to every callback invocation @param[in] callback called for every realised output @return NIX_OK if the build succeeded, or an error code if the build/scheduling/outputs/copying/etc failed. On error, the callback is never invoked and error information is stored in context.
