Rather than printing the SSL_ERROR_* constants, print the actual error.
This should be a bit more understandable. Debugging this also uncovered
some other issues on Windows:
- We were mixing up C runtime and Winsock errors, which are separate in
Windows.
- The thread local implementation interferes with WSAGetLastError due to
a quirk of TlsGetValue. This could affect other Windows consumers.
(Chromium uses a custom BIO, so it isn't affected.)
- SocketSetNonBlocking also interferes with WSAGetLastError.
- Listen for FD_CLOSE along with FD_READ. Connection close does not
signal FD_READ. (The select loop only barely works on Windows anyway
due to issues with stdin and line buffering, but if we take stdin out
of the equation, FD_CLOSE can be tested.)
