For the easy interface, the CURLOPT_MAXCONNECTS number goes for each
individual easy handle.

Since you can only do one connection at a time with the easy interface, the
logic is easier: CURLOPT_MAXCONNECTS sets the maximum amount of connections
that will be kept in the pool (and it will always be at least one).
