From: Geliang Tang <tanggeliang@xxxxxxxxxx> This patch uses the new helper connect_to_addr_str() in make_client() instead of using local defined function make_socket() + connect(). This local function can be dropped latter. A new parameter "expect_errno" is added for make_client() too to allow different "expect_errno" is passed to make_client(). It is used to check with "errno" after invoking connect_to_addr_str().
