This change makes send() / sendto() always block on Windows. It's needed because poll(POLLOUT) doesn't guarantee a socket is immediately writable on Windows, and it caused rsync to fail because it made that assumption. The only exception is when a SO_SNDTIMEO is specified which will EAGAIN. Tests are added confirming MSG_WAITALL and MSG_NOSIGNAL work as expected on all our supported OSes. Most of the platform-specific MSG_FOO magnums have been deleted, with the exception of MSG_FASTOPEN. Your --strace log will now show MSG_FOO flags as symbols rather than numbers. I've also removed cv_wait_example_test because it's 0.3% flaky with Qemu under system load since it depends on a process being readily scheduled.
