[PATCH] iproute2: add 64bit arches support to ifstat

ifstat assumes IFLA_STATS fields are "unsigned long", but they are
__u32. This fix is needed to let ifstat run on 64bit arches.

iproute_get will return cloned routes for IPv4
and cloned as well non-cloned routes for IPv6.

Therefore RTM_F_CLONED flag should not be checked
for iproute_get routes. Check in print_route will
always fail because valid values are 0 and 1.

The old 'ip addr flush' logic had several flaws:

* It reversed logic for primary v/s secondary flags
  (though, it sort of worked right anyway)

* The code tried to remove secondaries and then primaries,
  but in practice, it always removed one primary per loop,
  which not at all efficient.

* The filter logic in the core would run only the first
  filter in most cases.

* If you used '-s -s', the ifa_flags member would be
  modified, which could make future filters fail
  to function fine.

This patch attempts to fix all of these issues.

The u32 key match was incorrect byte order when using ether source
or destination address matching.

Fixes problems with xtables based MARK target ("ipt" module).
When tc loads the "ipt" (xt) module it kept the symbols local,
this made loading of libxtables not find the required struct.

currently ipt/xt is the only tc action module.
iproute2 never seem to do dlclose.
hopefully the modules doesn't export more symbols then needed.

In this situation hopefully the RTLD_GLOBAL flag won't hurt us.

The tc program searches LIBDIR by default for the .dist files, and that
defaults to /usr/lib.  But the netem subdir has /lib/ hardcoded which
means the default build+install results in the files not being found.

Further, these are plain text files which are read at runtime, so it
doesn't make sense to give them executable bits.

If basic match has no tree of matches underneath
then print_ematch would core dump.

Add all current values. Since if_arp.h is included, get rid
of ifdefs'. Make table constant.

Recent gcc doesn't like it when you cast char pointers to uint16_t
pointers and then dereference it.  So use memcpy() instead and let
gcc take care of optimizing things away (when appropriate).  This
should also fix alignment issues on arches where gcc packs the char
pointer tighter than 16bits.

The do_multirule logic was broken in batch mode because
it expected the preferred_family to be AF_INET or AF_INET6,
but it then assigned it to RTNL_FAMILY_IPMR or RTNL_FAMILY_IP6MR.
So, the next iteration of the batch processing, it failed
