Use socket_strerror, not plain strerror, to report the result of non-blocking

Browse Source 
connections in tcpip.cc. socket_strerror works with Winsock error codes whereas
plain strerror returns "Unknown error".

However, the error string for what is probably the most common error code,
WSAEWOULDBLOCK, is the big ugly "A non-blocking socket operation could not be
completed immediately.". Add a special case to use "Operation now in progress"
for that specific error.
