  to be due to two different flaws now fixed. Gil's excellent recipe helped me
  nail this.

much as possible in one go, as long as it doesn't block and hasn't reached the
end of the state machine.
This avoids spurious -1 returns from curl_multi_fdset() simply because
previously it would return from this function without anything in EWOUDLBLOCK
and thus basically it wasn't actually waiting for anything!!

state, we return CURLM_CALL_MULTI_PERFORM unconditionally then so that we
can act faster like in the case the protocol-specific connect doesn't block
on anything and we can just persue on the next action immediately. It also
then avoids a case where curl_multi_fdset() would return -1.

  included in release archives and forgetting to add files there is a common
  mistake. This is an attempt to make it harder to forget.

  ossl_connect_step3() increments an SSL session handle reference counter on
  each call. When sessions are re-used this reference counter may be
  incremented many times, but it will be decremented only once when done (by
  Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
  if this reference count remains positive. When a session is re-used the
  reference counter should be corrected by explicitly calling
  SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
  introducing a memory leak.
