Rewrite Windows connect()

Browse source 
Our old code wasn't working with projects like Qt that call connect() in
O_NONBLOCK mode multiple times. This change overhauls connect() to use a
simpler WSAConnect() API and follows the same pattern as cosmo accept().
This change also reduces the binary footprint of read(), which no longer
needs to depend on our enormous clock_gettime() function.
