/**
 * <pre>
 * 發送短消息的請求包，格式為：
 * 1. 包頭
 * 2. 消息序號，從0開始，用在拆分發送中
 * 3. 未知2字節，全0
 * 4. 未知4字節，全0
 * 5. 發送者昵稱，最長13個字節，如果不足，則后面為0
 * 6. 分隔符，1字節，0x01
 * 7. 如果是免提短信，0x20，其他情況，0x00
 * 8. 短消息內容類型，1字節
 * 9. 短消息內容類型編號，4字節
 * 10. 分隔符，1字節，0x01
 * 11. 未知的1字節，一般是0x00
 * 12. 分隔符，1字節，0x01
 * 13. 接受者QQ號，4字節
 * 14. 未知1字節，為0x03
 * 15. 短消息字節長度，2字節，QQ的短信和發送者昵稱加起來不能超過58個字符（英文和漢字都算是一個字符，
 * 	   但是漢字是兩個字節，要分清楚了），如果不是普通短消息，則為0x0000
 * 16. 短消息字節數組，消息的格式如下：
 * 		如果是普通的消息，則就是平常的字節數組而已
 *      如果有些字符有閃爍，則那些字節要用0x01括起來
 *      如果這條消息是一條長消息拆分而成的部分，則在消息字節數組前面要加4個字節，這4個字節分別是
 *      [消息序號的字符串形式，從1開始] [0x2F] [總消息條數的字符串形式] [0x0A]
 * 17. 尾部
 * </pre>
 * 
 * 調用這個包時，message的內容必須是已經組裝好的
