netstat: fix handling of large socket numbers

The kernel really only treats sockets with a value of -1 as an error.
The rest are an unsigned quantity.  So tweak the nestat lookup to use
an unsigned value.

patch based on Antonio Galea's work in Debian bug 345331

fix path to net-features.h

This was causing the %.o rule to get ignored which meant most of the
dependencies were ignored.

Once that gets fixed, we see that the %.o rule doesn't properly use
$(CPPFLAGS).  So add that while we're here.

Gentoo bug 379715

fix integer/pointer cast warnings

On 64bit systems where sizeof(void *) != sizeof(int), we get a warning
when trying to assign the return of atoi().  So insert a cast to avoid.

netstat: unify duplicate addr pretty printing

The tcp/udp/raw protocols duplicate the logic for looking up addresses and
their ports, and then formatting them nicely.  They also duplicate this for
local and remote addresses.  They also encode a few assumptions about the
length of the strings they get back which can cause buffer over and under
flows.

Add a new helper called addr_do_one that unifies all of this duplicate
logic in one place, and handles any string size correctly.
