(0ab045f xtables: fix missing ipt_entry for MASQUERADE target) broke
inversion of built-in selectors, such as -s, -d, etc.
We need to refresh the invflags if -p is used or set it for first
time if -p is not used, otherwise inversion is ignored.

The MASQUERADE target relies on the ipt_entry information that is
set in ->post_parse, which is too late.
Add a new hook called ->pre_parse, that sets the protocol
information accordingly.
Thus:
xtables -4 -A POSTROUTING -t nat -p tcp \
-j MASQUERADE --to-ports 1024
works again.

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.

The following patch implements the is_same operation
for ARP family needed for searching arp rule.

This should help Giuseppe with his ARP support works, this change
was missing in (618309c nft: refactoring parse operations for more
genericity).
Based on patch from Giuseppe.

This allows to reuse the nft_parse_* function for the bridge and
arp family (not yet supported).

Unfortunately, IPT_F_* and IP6T_F_* don't overlap, therefore, we have
to add an specific function to print the fragment flag, otherwise
xtables -6 misinterprets the protocol flag, ie.
Chain INPUT (policy ACCEPT)
tcp -f ::/0 ::/0
Note that -f should not show up. This problem was likely added with
the IPv6 support for the compatibility layer.

This helps to reduce the code complexity to have one single common path
for printing, saving and looking up for the rule.

Now, firewall rule printing is done through nft_family_ops
.print_firewall function. This moves generic part for ipv4 and ipv6 into
nft-shared.c, and enables reusing nft_rule_list() for other family such
as ARP which will be useful for arptables compatibility tool.

This makes nft core code independant from the family. Each family needs
to implement and provide a struct nft_family_ops {}.
This split will ease the future support of bridge and arp rules manipulations.
