By introducing an internal alternative to curl_multi_init() that accepts parameters to set the hash sizes, easy handles will now use tiny socket and connection hash tables since it will only ever add a single easy handle to that multi handle. This decreased the number mallocs in test 40 (which is a rather simple and typical easy interface use case) from 1142 to 138. The maximum amount of memory allocated used went down from 118969 to 78805.
