The patch fixes several strncpy() calls to properly set '\0' in the end

coccinelle script:

All found cases were manually checked, some of them were false
positives.  Some code doesn't need = '\0', but needs changes to the size
argument.

strncpy() from libpcap/ need additional review as it looks like several
strncats deliberately don't add zero at the end of the string to satisfy
setsockopt/getsockopt API.

Thank you for doing this check. Rather than manually zero the last byte,
it were better to use the Strncpy function from nbase.

I wanted the changes to be consistent with the surrounding code.

I'd prefer that you use Strncpy. It is already used in many places in
Nmap. Would you revise the patch to use Strncpy?
