curl_multi_socket_action does all actions required for executing
transfer(s) such as connect, read/write data, call user specified
callbacks(socket, read, write, debug, timer, progress), etc.

All callbacks are invoked (and other operations are done), in the same
thread which calls the curl_multi_socket_action.
