Subject: [PATCH 1/5] Work around file size issues at 32 Bit systems

Replace stream_copy_to_stream with a chunked process, to handle file sizes hat do not fit into an integer.
Implementation according to http://php.net/manual/en/function.stream-copy-to-stream.php#98119, proposed and implemented by https://github.com/rikmeijer in https://github.com/nextcloud/server/issues/1707#issuecomment-291835214.
