ebtables-nft has always supported both intra- and extrapositioned
negations but defaulted to intrapositioned when printing/saving rules.
With commit 58d364c7120b5 ("ebtables: Use do_parse() from xshared")
though, it started to warn about intrapositioned negations. So change
the default to avoid mandatory warnings when e.g. loading previously
dumped rulesets.
Also adjust test cases, help texts and ebtables-nft.8 accordingly.

Can't use XTTYPE_MARKMASK32 here because in 'val/mask', 'val' is
optional. Would have to extend xtopt_parse_markmask() to accept this,
maybe guarded by a new XTOPT_ flag to avoid unexpected changes in
behaviour?

Extension data is zero by default.

This reverts commit 5f508b76a0cebaf91965ffa678089222e2d47964.
While attempts at unifying syntax between arp-, eb- and iptables-nft
increase the opportunity for more code-sharing, they are problematic
when it comes to compatibility. Accepting the old syntax on input helps,
but due to the fact that neither arptables nor ebtables support --check
command we must expect for users to test existence of a rule by
comparing input with output. If that happens in a script, deviating from
the old syntax in output has a high chance of breaking it.
Therefore revert Florian's patch changing inversion character position
in output and review the old code for consistency - the only thing
changed on top of the actual revert is ebtables' own copy of
print_iface() to make it adhere to the intrapositioned negation scheme
used throughout ebtables.
Added extension tests by the reverted commit have been kept.

This allows gcc to check format string vs. passed arguments.
Fix the fallout from this as well, typical warning produced is:
libebt_mark_m.c:112:28: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' [-Wformat=]
xt_xlate_add(xl, "and 0x%x %s0 ", info->mask, ...
~^ ~~~~~~~~~~
so add the required casts or fixup format strings as needed.
libxt_conntrack also passed an unneeded argument (port), so remove that.

in the iptables universe, we enforce extrapositioned negation:
! -i foo
"-i ! foo" is not even supported anymore.
At least make sure that ebtables prints the former syntax everywhere as
well so we don't have a mix of both ways.
Parsing of --option ! 42 will still work for backwards compat reasons.

The struct of the type option is only used to initialise a field
inside the xtables_match struct and is not modified anywhere.
