Add -n option to netstat

[mjw]

I have produced a small patch to src/bin/netstat/netstat.cpp to prevent netstat resolving names. This functionality is enabled by the -n switch as in most other OSs.

Thanks for the patch! I would like to apply it, but there are many coding style related issues - please have a look at ​http://haiku-os.org/documents/dev/haiku_coding_guidelines and resubmit your patch; a few hints:

• opening parenthesis go to the end of the previous line in line 154
• variables don't use '_' to separate words, but inter-caps formatting (ie. optionIndex)
• static global variables are named like sThisIsAStaticVariable.

OK, I'll work on that.

I have also noticed that gethostbyaddr() is called incorrectly. It is being called as: gethostbyaddr((const char *)_address,...), whereas it should be called as gethostbyaddr((const char *)&address.sin_addr,...).

Do you want me to roll that fix into this patch, or should I create a new bug to deal with that?

Thanks!

Nice catch, I've already fixed the problem in hrev23223.

I hope this one is more acceptable

Absolutely! Thanks, I've applied it in hrev23252. I've only made two minor changes: I removed the superfluous parentheses around "address.sin_addr", and I added you to the list of authors.
