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.
