Cross platform correct socket error code

A friend using my networking code made the good point that it was not correctly reporting errors on some windows compilers.

I hope we got this sorted out.

Grab / update your code from the git repo:

-netw_unload() =>macro who calls WSACleanup . Call it before exiting (on OK or error). Does nothing on *nix/*nux

-netw_set_blocking(…) => set blocking mode on a network

-neterr => WSAGetLastError or errno
-netstrerr => FormatMessage or strerror (strerror_r wrapper is quoted because not working on redhat)

This has caused a full revamping of all error management, but now it’s ok. Valgrind checked.
