If error happens while reading file, we return
:macro:`NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. This tells the library
to send RST_STREAM to the stream. When all data is read, set 1 to
``*eof`` to tell the nghttp2 library that we have finished reading
file.

The `nghttp2_submit_response()` is used to send response to the remote
