[components][at] 优化AT组件，并解决内存泄露 
1.优化at server endmark判断，支持自动识别'\r''\n'"\r\n"。
2.优化at_recvfrom,修复大数据量时sem多次释放造成的接收错误。
3.修复at组件中可能存在的内存泄露。
4.优化部分代码逻辑，减少冗余代码。

wenbodong2015 b9d24aff61 解决at_socket在极限情况下内存泄漏问题 
AT模块在执行AT+CLOSE并返回OK后，在实际关闭前（上报URC前）仍然有
可能接收到数据。所以接收数据时需要判断状态是否为AT_SOCKET_CONNECT。

另，at_recv_notice_cb在拒绝数据包时，没有释放数据包内存，从而导致
内在泄漏。

wenbodong2015 e38a8e9378 解决at_socket编译失败的问题 
失败现象为“找不到EAGAIN”，此问题由libc改动引发。

longtengmcu aac5e9da4c 1、web socket请求数据从服务器回来时，服务器会关闭连接，此时AT socket在读取返回的数据时不应该判断socket为连接的状态 
2、sal socket在支持多网卡时，sal_getaddrinfo从A网卡获取的地址信息，在sal_freeaddrinfo释放时必须由A网卡进行释放

senduo 350947b190
修改at_socket.c文件中的sendto函数，len局部变量没有给初始值 
len值如果不给初始值0，到最后__exit的时候，result = len会导致result的值变成一个不可预估的值，进而导致mbedtls库的while循环无法正常结束，其中mebedtls中发生异常的地方在ssl_tls.c文件中的mbedtls_ssl_flush_output函数while( ssl->out_left > 0 )，因为out_left 是一个无符号整型，退出的条件只能是 out_left = 0,又因为这里面的len没有给初始值0，返回出来的值是一个很大的整型数字，导致了mbedtls中的死循环
