Add support to fs.createWriteStream and fs.createWriteStream for an autoClose
option that behaves similarly to the autoClose option supported by
fs.createReadStream and fs.ReadStream.

When an instance of fs.createWriteStream created with autoClose === false finishes,
it is not destroyed. Its underlying fd is not closed and it is the
responsibility of the user to close it.
