As pointed out by Peter Hoelsken, rules created with non-standard
masks such as 0.255.0.0, 0.0.255.0, etc. are displayed when output
with iptables -L in CIDR notation as -1. This is because the cidr
variable in xtables_ipmask_to_numeric is unsigned, and the return
value of -1 from xtables_ipmask_to_cidr is therefore converted to
UINT_MAX. Add a cast to workaround the issue.
This closes netfilter bugzilla #854.

Similar to how iptables does not print /32 on IPv4 addresses, ip6tables
should not print out /128 on IPv6 addresses.

After upgrade from iptables 1.4.8 to 1.4.18 netmask parsing got broken:
-A foo -m policy --mode tunnel --dir in --tunnel-src 192.168.123.0/255.255.255.0 -j RETURN
With iptables 1.4.18:
iptables-restore v1.4.18: policy: bad value for option "--tunnel-src", or out of range (0-32)
This was probably broken by the augmented parser.

This function is used both by iptables and ip6tables, and
refactorize to avoid longer than 80-chars per column lines
of code.

This function is shared by iptables and ip6tables.

Commit v1.4.16-1-g2aaa7ec is testing for real_name (not) being NULL
which was always false (true). real_name was never NULL, so cs->jumpto
would always be used, which rendered -j NOTRACK unusable, since the
chosen real name.revision is for example NOTRACK.1, which does not exist
at the kernel side.
# ./iptables/xtables-multi main4 -t raw -A foo -j NOTRACK
dbg: Using NOTRACK.1
WARNING: The NOTRACK target is obsolete. Use CT instead.
iptables: Protocol wrong type for socket.
To reasonably support the extra-special verdict names, make it so that
real_name remains NULL when an extension defined no alias, which we can
then use to determine whether the user entered an alias name (which
needs to be followed) or not.
[ I have mangled this patch to remove a comment unnecessarily large.
BTW, this patch gets this very close to the initial target aliasing
proposal --pablo ]

This patch allows for match names listed on the command line to be
rewritten to new names and revisions, like we did for targets before.

This patch allows for target names listed on the command line to be
rewritten to new names and revisions.
As before, we will pick a revision that is supported by the kernel - now
including real_name in the search. This gives us the possibility to test
for many action names.

Alias support will require testing for more conditions, so move the
revision comparison code into a separate function where it can be
shared between matches and targets.

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).

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.
