Extend RED testsuite to cover the new nodrop mode of RED-ECN. This test is really similar to ECN test, diverging only in the last step, where UDP traffic should go to backlog instead of being dropped. Thus extract a common helper, ecn_test_common(), make do_ecn_test() into a relatively simple wrapper, and add another one, do_ecn_nodrop_test().
