Since it's no longer relevant whether an IP address is primary or
secondary when flushing, ipaddr_flush() can be simplified a bit.

I found recently that, if I disabled address promotion in the kernel, that
ip addr flush dev <dev>

would fail with an EADDRNOTAVAIL errno (though the flush operation would in fact
flush all addresses from an interface properly)

Whats happening is that, if I add a primary and multiple secondary addresses to
an interface, the flush operation first ennumerates them all with a GETADDR |
DUMP operation, then sends a delete request for each address.  But the kernel,
having promotion disabled, deletes all secondary addresses when the primary is
removed.  That means, that several delete requests may still be pending in the
netlink request for addresses that have been removed on our behalf, resulting in
EADDRNOTAVAIL return codes.

It seems the simplest thing to do is to understand that EADDRUNAVAIL isn't a
fatal outcome on a flush operation, as it just indicates that an address which
you want to remove is already removed, so it can safely be ignored.

The algorithm depends on the loop counter ('i') to increment by one in
each iteration. Though if running endlessly (count==0), the counter was
not incremented at all.

Also change formatting of the header printing conditional a bit so it's
hopefully easier to read.

In iptunnel, declare loop variables inside the loop as done in
ip6tunnel.

Fix and simplify goto logic in ip6tunnel:
- Failure to read over header lines would have left fp opened.
- By returning directly upon fopen() failure, fp can be closed
  unconditionally in the end.

Use the same goto logic in iptunnel, as well.

Instead of duplicating the same code six times (key, ikey and okey in
iptunnel and ip6tunnel), have a common parsing routine. This has the
added benefit of having the same verbose error message in ip6tunnel as
well as iptunnel.

I'm not sure if parsing an IPv4 address as key makes sense for
ip6tunnel, but the code was there before so this patch at least doesn't
make it worse.
