This structure is an extensible containers of parameters, so we don't
need to propagate interface updates in every extension file in case
we need to add new parameters in the future.

The multiport match needs it, this basically leaves ->xlate() indirection
with almost the same interface as ->print().

Add translation for masquerade to nftables.
Examples:
$ sudo iptables-translate -t nat -A POSTROUTING -j MASQUERADE
nft add rule ip nat POSTROUTING counter masquerade
$ sudo iptables-translate -t nat -A POSTROUTING -p tcp -j MASQUERADE --to-ports 10
nft add rule ip nat POSTROUTING ip protocol tcp counter masquerade to :10
$ sudo iptables-translate -t nat -A POSTROUTING -p tcp -j MASQUERADE --to-ports 10-20 --random
nft add rule ip nat POSTROUTING ip protocol tcp counter masquerade to :10-20 random

Due to the use of printf("foobar "), iptables emits spaces at the
end-of-line, which looks odd to some users because it causes the
terminal to wrap even if there is seemingly nothing to print.
It may also have other points of annoyance, such as mailers
interpreting a trailing space as an indicator that the paragraph
continues when format=flowed is also on.
And git highlights trailing spaces in red, so let's avoid :)
Preexisting inconsistencies in outputting spaces in the right
spot are also addressed right away.

Rewrite port range validator to use xtables_strtoui() and
xtables_param_act(). Original check failed to recognize
such port range errors as "1a-2" and "1-2a".
Also, original parser erroneously denied using port 0,
which is now allowed.

In going to fix NF bug #611, "argv" is needed in
xtables_check_inverse to set "optarg" to the right spot in case of an
intrapositional negation.

iptables.h and ip6tables.h only include declarations internal to
iptables (specifically iptables.c and ip6tables.c), as most of the
public API has been moved to xtables.h a few months ago.

Give symbols of libxt targets unique names (2/3).
Adds unique prefixes to all functions (most of them - especially the hook
functions) so that debugging programs can unambiguously map a symbol to an
address. Also unifies the names of the xtables_match/xtables_target structs,
(based upon libxt_connmark.c/libip6t_*.c).

This changes the type of arguments as follows in multiport, DNAT, SNAT,
MASQUERADE, and REDIRECT
- ip[6]t_ip[6] * -> void *
- ip[6]t_entry * -> void *
and adds lines to cast these pointer with intended type.
