Sadly not the best conversion, struct arpt_mangle is not ideal for use
as storage backend: With MAC addresses, xtopt_parse_ethermac() refuses
to write into *_devaddr fields as they are larger than expected. With
XTTYPE_HOSTMASK OTOH, XTOPT_PUT is not supported in the first place.
As a side-effect, network names (from /etc/networks) are no longer
accepted. But earlier migrations to guided option parser had this
side-effect as well, so probably not a frequently used feature.

ARPT_ and IPT_INV flags are not interchangeable, e.g.:
define IPT_INV_SRCDEVADDR 0x0080
define ARPT_INV_SRCDEVADDR 0x0010
as these flags can be tested by libarp_foo.so such checks can yield
incorrect results.
Because arptables-nft uses existing code, e.g. xt_mark, it makes
sense to unify this completely by converting the last users of
ARPT_INV_ constants.
Note that arptables-legacy does not do run-time module loading via
dlopen(). Functionaliy implemented by "extensions" in the
arptables-legacy git tree are built-in, so this doesn't break
arptables-legacy binaries.

It will be referenced by xtables_printhelp() if printing for arptables
and therefore must be present in legacy as well even if unused.

Adding a parser which supports common names for special MAC/mask
combinations and a print routine detecting those special addresses and
printing the respective name allows to consolidate all the various
duplicated implementations.
The side-effects of this change are manageable:
* arptables now accepts "BGA" as alias for the bridge group address
* "mac" match now prints MAC addresses in lower-case which is consistent
with the remaining code at least

arptables-save will show
-A OUTPUT --h-length 6 --h-type 1 -j MARK --set-xmark 0x1/0xffffffff
as
--h-length 6 --h-type Ethernet -j MARK MARK set 0x1
Because it uses ->print() instead of ->save().
Switch it to use ->save, we can then also drop special handling of
CLASSIFY target.

This changes mangle target to print whitespace before each option, not
afterwards. This fixes any cases of trailing or double whitespace in
arptables output.
While being at it, introduce ipaddr_to() helper in libarpt_mangle.c to
simplify arpmangle_print() a bit.

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

This patch adds support to use the mangle target extensions, along with
the required changes in the surrounding code.
