/** Write a potentially long string as UTF8<br>
 * The ByteBufInputStream.readUTF() and writeUTF() calls use the first two bytes of the message
 * to encode the length of the string, which limits the string length to 64k.
 * This method gets around that limitation by using a four byte header.
 * @param s The string we are sending
 * @param bbos The ByteBufOutputStream we are writing to
 * @throws IOException
