working on inetutils

I have been working on inetutils for some time. Recently added BSD options –timeout (equivalent to -w) and about to write down –timeout-response (equivalent to -W) to ping/ping6. Now is time to remove all redundant calls to sys/socket api and integrate both commands as much as possible.

I will be picking next tasks from TODO. 1.6 release needs lot of work.

Thanks Alfred for all review work 🙂
