conn->err is currently wildly read and set from both application tasks and the tcpip_thread. It is also used as return value for netconn-functions running in tcpip_thread (which could result in wrong return values for netconn_* functions). |

Corresponding source code
Done by adding error return value to struct api_msg_msg. The commit is a bit lengthy...
This also made it necessary to save the struct api_msg_msg pointer while connect/close is in progress (like currently done on write).
