Windows: an error set where socket errors are read

Browse Source 
errno is WSAGetLastError() on Windows, but seterrno3() set the C
library's errno there: the EAGAIN of a TLS read or write wanting the
socket again was not seen as one, and the error left was whatever the
socket call before had set. seterrno3() sets the socket error now.

socks.c assigned errno directly, which does not build on Windows.
