<config.h> is generated by the configure script. As it contains our
feature detection, it want to use it everywhere.
Likewise, in some of our sources, we define _GNU_SOURCE. Such defines
should also be defined before anything else. And there is no reason for
not defining it for all our sources. It would be good to use autoconf's
AC_USE_SYSTEM_EXTENSIONS, in which case we would also need to ensure
that <config.h> is always included as first.
Instead of going through all source files and include <config.h> as
first, add a new header "include/nftdefault.h", which is supposed to be
included in all our source (and as first).
This will also allow us to prepare some common base, like include
<stdbool.h> everywhere.
The aim that internal headers are self-contained, so that they can be
included in any order. Which, by the way, already didn't work because
some headers define _GNU_SOURCE, which would only work if the header
gets included as first. There is however an exception to the rule:
everything we compile shall rely on having <nftdefault.h> header
included as first. This applies to source files (which include it as
first) and to internal header files (which are always included after).
Note that <config.h> has no include guards, which is at least ugly to
include multiple times. It doesn't cause problems in practice, because
it only contains defines and the compiler doesn't warn about redefining
a macro with the same value. Still, <nftdefault.h> ensures to include
<config.h> exactly once.

There is a minimum base that all our sources will end up needing. That
is what <nftdefault.h> provides.
Add <stdbool.h> and <stdint.h> there. It's unlikely that we want to
implement anything, without having "bool" and "uint32_t" types
available.
Yes, this means the internal headers are not self-contained, with
respect to what "nftdefault.h" provides. This is the exception to the
rule, where headers on having "nftdefault.h" included for them.
