Subject: [PATCH 1/4] Share DNS and Connect between curl requests

reduces overhead when doing multiple curl requests per php-request.

other places which manually invoke `curl_init` can benefit in a similar way by adding such code.
`curl_multi_*` will automatically share caches between requests, without the need for additional code.
