* use stream_copy_to_stream

it's simpler, and should be faster.
For example, stream_copy_to_stream can use sendfile ( https://man7.org/linux/man-pages/man2/sendfile.2.html ) on operating systems supporting it, which is faster and use less RAM than fread()+fwrite() (because it avoids copying data to/from userland, doing the copy entirely in-kernel~)

* fix loop early return, and workaround bug

* use feof
