Subject: [PATCH] Consolidate DEBUGP macros

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1668475
Upstream Status: iptables commit 78b9d438037f2
Conflicts:
* Context change due to missing commit 2963a8df2175b
  ("iptables: Remove explicit static variables initalization.")
* Dropped changes to non-existing files iptables/nft-shared.h and
  iptables/xtables-restore.c.

commit 78b9d438037f2c83a7bbb73eb1b86cc295967905
Author: Phil Sutter <phil@nwl.cc>
Date:   Thu Aug 2 17:05:15 2018 +0200

    Consolidate DEBUGP macros

    This debug printing macro was defined in various places, always
    identical. Move it into xshared.h and drop it from sources including
    that header. There are a few exceptions:

    * iptables-xml.c did not include xshared.h, which this patch changes.

    * Sources in extensions and libiptc mostly left alone since they don't
      include xshared.h (and maybe shouldn't). Only libxt_set.h does, so
      it's converted, too.

    This also converts DEBUG define use in libip6t_hbh.c to avoid a compiler
    warning.
