Make sure that `io_need` is cleared and set at the filter operations. Add some more tracing for shutdown situations. Improve shutdown handling for blocked sends. OpenSSL is a bit tricksy here that it only reports WANT_WRITE on SSL_shutdown(), but never on SSL_read() on blocked sends. So we need to use both. At last, set SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when available since we are not always retrying sends from the very same address, as testing showed.
