fu_copy_stream0 has had no caller since b26846b replaced both uses with direct IO.copy_stream calls in 2008. The retained private wrapper is unreachable.

FileUtils::StreamUtils_#fu_copy_stream0is a private, undocumented helper with no callers.Commit b26846b replaced both of its callers with direct
IO.copy_streamcalls in 2008, but retained the wrapper itself. It has been unused ever since.This removes the unreachable helper.
