This patch adds generic functions to return the mask in CIDR
notation whenever is possible.
This patch also simplifies xtables_ip[6]mask_to_numeric, that
now use these new two functions.
This patch also bumps libxtables_vcurrent and libxtables_vage
since we added a couple new interfaces (thanks to Jan Engelhardt
for his little reminder on this).

Have each extension link against libxtables.so; with this, all home
symbols are known at link time and we can use ld's --no-undefined to
run the check, dropping the homebrew solution.
By having libxtables.so required by extensions, package managers'
automatic dependency discovery will become effective so that manual
dependencies for distros with split extension packages (e.g. OpenWRT)
will not be necessary anymore.

iptables(exe) requires libext.a, but extensions/ require libxtables.la
(in iptables/). This circular dependency does not work out, so
separate libxtables into its own directory and put it in front.

This is just to make sure that projects (still) using it do so with
the right cflags, e.g. for when the include file ends up in a
non-standard location due to ./configure having been called with
--include=/somewhere/else.

iptables no longer compiles for Linux 2.4 because it uses
linux/magic.h. This header and the PROC_SUPER_MAGIC macro are only for
Linux 2.6.

xtables.c: In function 'proc_file_exists':
xtables.c:389: error: 'PROC_SUPER_MAGIC' undeclared (first use in

once for each function it appears in.)

Since libiptc does not reference any symbols in libip(4|6)tc, the linker
may ignore the dependencies. Use --no-as-needed to explicitly force a
DT_NEEDED entry.

xt_osf is pretty useless without the actual fingerprint loader. Import
nfnl_osf-2009-06-07 and make it a part of the iptables distribution.

libiptc already supports adding and deleting multiple rules with

This also skips building the IPv6 extensions. It does not #ifdef out
all code however, I think that would make it too ugly.

When the structure's layout changes, as it did between v1.4.1 and
v1.4.2, trying to compare the version string makes iptables segfault
while it tries to determine whether the module is compatible in the
first place.
By moving the member to a known offset in the struct and keeping it
there, objects (both iptables and 3rd party) compiled from this
commit onwards will avoid the segfault.

Split XTABLES_VERSION into xtables and iptables, and encode the
xtables soversion into the extensions instead. This makes it possible
to upgrade iptables without having to recompile 3rd-party extensions
(if the libxtables version matches, of course).
