[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。

[at] optimize at_vprintfln 
为什么提交这份PR (why to submit this PR)
现在的at指令发送接口，底层会自动添加"\r\n"，某些场景需要发送空指令。如ESP32的蓝牙发送数据指令，收到">"后
发数据，等待接收OK。

详细讨论可见：
https://club.rt-thread.org/ask/question/185810c0aed98558.html

你的解决方案是什么 (what is your solution)
判断at指令长度，长度为0，则直接返回

SNOWA 3400a79035 Update at_utils.c 
如果打印格式为"%02X"的数据大于0x7F,打印的数据就会在前面多出6个'F',原因详见https://blog.csdn.net/zqxwce821/article/details/53011925。
现在通过强制转换成unsigned char后，在STM32（KEIL5+C99）已测试确认能修复该问题。

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。
