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.
