2f117add7a sockets: task #14247, add CMSG and IP_PKTINFO 
This commit adds CMSG infrastructure (currently used with recvmsg) and
the IP_PKTINFO socket option.

In order to use IP_PKTINFO, set LWIP_NETBUF_RECVINFO to 1

Unit test is added to verify this feature

8e83e206f4 sockets.c: Make sock_inc_used overflow check robust. 
Before this patch, it was possible that the overflow check might
miss an overflow event.

e.g. Consider 2 threads, both executing this method. u8_t fd_used is on 255...

Thread A -> atomically increment fd_used (which is now 0)
Thread B -> atomically increment fd_used (which is now 1)
Thread A -> check overflow... sees everything ok
Thread B -> check overflow... sees everything ok

And the overflow is missed :(

0b2a652317 api_msg: Use lwip_netconn_is_err_msg instead of NULL test in netconn_drain() 
The NULL test no longer work after commit e0a2472706ee, it needs to test with
lwip_netconn_is_err_msg() instead.

Fixes: e0a2472706ee ("netconn/sockets: remove fatal error handling, fix asynchronous error handling, ensure data before RST can be received")
