Removes wrong conditions in flags translating functions
that doesn't permit to delete rule with inverse flags set.
For instance, the following command doesn't remove the rule:
arptables-compat -D INPUT -i ! eth1 -j ACCEPT

This patch prints the counters of a rule before the details,
like iptables-save syntax.

Since the family declaration has been modified in libnftnl,
from commit 3cd9cd06625f8181c713489cec2c1ce6722a7e16
the assertion is failed for {ip,ip6,arp}tables-compat
when printing rules.
iptables-compat -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
libnftnl: attribute 0 assertion failed in rule.c:273
ip6tables-compat -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
libnftnl: attribute 0 assertion failed in rule.c:273
arptables-compat -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
libnftnl: attribute 0 assertion failed in rule.c:273

the current condition doesn't permit to parse ip addresses
when they should be. Obviously they are not printed.
arptables-compat -A INPUT -s 1.1.1.1 -i eth0 -j ACCEPT
arptables-compat -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
-j ACCEPT -i eth0

Wrong arguments are passed to is_same_interfaces
that causes sometimes to delete a wrong rule.
See the example below:
arptables-compat -A INPUT -i eth0 -j ACCEPT
arptables-compat -A INPUT -i eth1 -j ACCEPT
arptables-compat -A INPUT -i eth2 -j ACCEPT
arptables-compat -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
-j ACCEPT -i eth0
-j ACCEPT -i eth1
-j ACCEPT -i eth2
arptables-compat -D INPUT -i eth2 -j ACCEPT
arptables-compat -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
-j ACCEPT -i eth1
-j ACCEPT -i eth2

This patch replaces strcat with strncat and strcpy with strncpy
fixing possible string overflow.

This patch adds parse_target for arp family, fixing segfaults
for xtables-arp -L after rules like:
xtables-arp -A OUTPUT -o eth0 -j CLASSIFY --set-class 0:7
xtables-arp -A OUTPUT -o eth1 --h-length 6 \
-j mangle --mangle-mac-s 01:00:5e:00:01:01

This patch removes nft_arp_rule_new, which almost a copy and paste
of the original nft_rule_new. This patch generalizes the
infrastructure to support ARP.

This patch kills nft_arp_rule_find, which is almost a copy and paste
of the original nft_rule_find function. Refactor this function to
move specific protocol parts to the corresponding nft-{ipv4,ipv6,arp}.c
files.

nft_arp_print_firewall already handles endianess appropriately.
This fixes the output of the option that allows you to match
ARP header fields.

This patch bootstraps ARP support for the compatibility layer:
1) copy original arptables code into xtables-arp.c
2) adapt it to fit into the existing nft infrastructure.
3) add the builtin table/chains for ARP.
4) add necessary parts so xtables-multi can provide xtables-arp.
5) add basic support for rule addition (-A), insertion (-I) and
listing (-L).
[ This was originally posted in a series of patches with interdependencies
that I have collapsed to leave the repository in consistent state. This
patch includes the following changes I made:
* Rename from xtables-arptables to xtables-arp, previous name too long.
* Remove nft-arptables.c, now we have one single nft-arp.c file. Moved
specific ARP functions to nft.c. Those should go away at some point as
some refactorization should allow to accomodate those functions to the
existing infrastructure.
* Fix --opcode Request/Reply, so we can do something useful with this
like dropping ARP request/replies.
