purpose, extra content. for unknown
type, front three is the same, after is unknown
of QQ_SYS_BEING_ADDED_EX, message text format is:
i. byte length of follow content
ii. unknown content, don't know how to decrypt

of QQ_SYS_ADD_FRIEND_REQUEST_EX, message text format is:
i. byte length of message text
ii. message text
iii. whether allow the other side to add me as friend, 0x01 means yes, 0x02 means not

系统消息包，系统消息和ReceiveIMPacket里面的系统通知有什么区别呢？
系统消息是表示你被别人加为好友了之类的消息，所以有源有目的，其他人
收不到的，系统通知是系统发给大家的消息。好了，废话这么多，系统消息的
格式是:
1. 头部，头部说明了系统消息的类型，目前已知的有四种
2. 对于一般的系统通知，其格式为:
以0x1F相隔的多个字段，对于已知的类型，分别是消息类型，源，目的，附加内容，对于未知的
消息类型，前面三个是一样的，后面的就未知了

对于QQ_SYS_BEING_ADDED_EX，消息正文的格式为：
i. 后面内容的字节长度
ii. 未知内容，不知用什么才能解密

对于QQ_SYS_ADD_FRIEND_REQUEST_EX，其消息正文的格式为
i. 消息正文字节长度
ii. 消息正文
iii. 是否允许对方加自己为好友，0x01表示允许，0x02表示不允许

对于QQ_SYS_ADD_FRIEND_APPROVED_AND_ADD，其消息正文的格式为
i. 未知的1字节，0x00
3. 尾部

Note: only use 0x00A8 of 2005 to send authentication message, will receive QQ_SYS_ADD_FRIEND_REQUEST_EX message Note: 只有使用2005的0x00A8发送认证消息，才会收到QQ_SYS_ADD_FRIEND_REQUEST_EX消息
