rtthread添加CoAP package编译出错的问题

测试步骤如下：
1. 从gitee上下载 最新的rt-thread源代码
```
git clone https://gitee.com/rtthread/rt-thread
```
2. 源代码下载后，进入源码目录`rt-thread\bsp\stm32f10x-HAL`，打开evn，执行`menuconfig`，使能`CoAP package`
3. 保存配置，执行`pkgs --update`
4. 执行`scons`
5. 编译提示如下错误

>你好，你的问题解决了吗？
我的也出现了这个问题，编译出现好多错误。

无论是否使用 SAL 都会出现错误，我把未定义的东西，一通加之后，倒是能编译过去，但加的地方并不合适，这里先给出我增加的部分，后面给出官方版本：

修改`components\net\sal_socket\include\sal_socket.h`，如下所示：

```c
struct sockaddr_in6 {
  u8_t            sin6_len;      /* length of this structure    */
  sa_family_t     sin6_family;   /* AF_INET6                    */
  in_port_t       sin6_port;     /* Transport layer port #      */
  u32_t           sin6_flowinfo; /* IPv6 flow information       */
  struct in6_addr sin6_addr;     /* IPv6 address                */
  u32_t           sin6_scope_id; /* Set of interfaces for scope */
};

extern const struct in6_addr in6addr_any;
#define IP_CLASSD(a)        (((u32_t)(a) & 0xf0000000UL) == 0xe0000000UL)
#define IP_CLASSD_NET       0xf0000000          /* These ones aren't really */
#define IP_CLASSD_NSHIFT    28                  /*   net and host fields, but */
#define IP_CLASSD_HOST      0x0fffffff          /*   routing needn't know. */
#define IP_MULTICAST(a)     IP_CLASSD(a)

#define IN_MULTICAST(a)     IP_MULTICAST(a)
```
