This is a series of cleanups to make newlib.hin be managed automatically
by autoheader instead of being hand maintained. This will also make the
standard autoreconf command not fall over due to the current poor state
of the header files, as well as not make it corrupt/clobber the version
header file.
I've split these up to (hopefully) make it easier to review, and be easy
to merge most of them independently. If there is some reason we don't
want to actually leverage autoheader, or maybe we want to rework how the
final step is done, we can still land the rest of the stack while that
discussion is ongoing.

This define is only used by newlib internally, so stop exporting it
as HAVE_INITFINI_ARRAY since this can conflict with defines packages
use themselves.
We don't really need to add _ to HAVE_INIT_FINI too since it isn't
exported in newlib.h, but might as well be consistent here.
We can't (easily) add this to newlib_cflags like HAVE_INIT_FINI is
because this is based on a compile-time test in the top configure,
not on plain shell code in configure.host. We'd have to replicate
the test in every subdir in order to have it passed down.

The acconfig.h header was used to run autoheader and then manually
sync the output into newlib.hin. Based on how the files have fallen
out of sync (with newlib.hin having many more templates), this has
not been run in a long time, and attempts to do so now would break
newlib.hin.
Further, if you try to run autoheader now, it will automatically
replace _newlib_version.hin since it's the first entry in the call
to AC_CONFIG_HEADERS.
So let's throw away acconfig.h entirely. It only had 2 slightly
better comments, and the rest were either worse, missing, or stale.
This has the side benefit of avoiding autoheader warning about the
deprecated use of acconfig.h since newer autoconf only wants macro
calls in configure.ac.

Sync these back from newlib.hin to configure.ac, and touchup some of
the forms to be consistent (like being full sentences). Also use the
AC_DEFINE-vs-AC_DEFINE_UNQUOTED macros correctly. This will make it
easier to re-enable autoheader for managing newlib.hin.

Sort the symbols lexically like autoheader does. There are no other
changes in here. This will make it easier to sync with autoheader.

This will make it easier to move newlib.h to use autoheader directly.
We only want the newlib version defines in our hand curated version
file, _newlib_version.h, not in the template header, newlib.h, so
using AC_DEFINE doesn't make much sense.

This was added to configure, but never to the header file. Nothing
uses this currently, so it's not a big deal (as all the dynamic logic
is via automake conditionals), but might as well restore it now to
keep autoheader output in sync.

The list of iconv to/from defines is hand maintained in newlib.hin.
Lets leverage mkdeps.pl to generate this list automatically from the
list of known encodings. The newlib.hin list is up-to-date, so the
list in iconv.m4 matches the list already generated.

Now that newlib.hin has been brought up to date and all of its defines
are produced by configure, we can switch it to using autoheader without
manual editing. This relies on a few pieces:
* Moving the header & footer into configure.ac via AH_TOP & AH_BOTTOM.
* Running a post-process step on newlib.h to delete all the defines we
didn't export ourselves. Basically, anything without a _ prefix.
This will leave behind some spurious comments in newlib.h related to
the defines we filtered out, but should be harmless, so it's probably
not worth the effort to construct a more complicated sed expression to
also strip those out.

How do you know it is only used by Newlib internally? Changing this
is effectively changing the API and is not safe. (I don't use it, myself,
but given it's been like this for a long time, there's nothing to say that
nobody is.) Unfortunately, it uses a methodology as either being defined
or not, so someone using the #ifdef method on it would not immediately
notice the change. (That is, when building with something that looked at
it, the build itself could not know something had gone wrong. It would
require runtime to find out.)
This does not necessarily mean that this specific change ought not be
done, but it does mean that this consideration needs to be weighed before
an API-breaking change were made. Offhand I can't think of a good way to
guard against it, either. (A tedious way would be to mark it deprecated
and then remove it in a year or so.)

any project relying on this is broken. exporting this symbol violates standards
as to the namespace C libraries are allowed to use. in fact, a cursory search
shows that it is breaking projects because they were using this define, but the
newlib symbol override their configure tests leading to desyncs.
we also don't export HAVE_INIT_FINI, so newlib users aren't able to determine
how newlib is actually going to behave at run time.
there is no way to mark a preprocessor symbol as deprecated such that the
toolchain will warn. we can put a note in the docs/NEWS, but that requires
people actually read them. and if they're reading those, then we can just
as easily put mention that the symbol has been removed.
i really don't think this is a big deal. arguing theory isn't useful here.
if an actual user comes out of the woodworks, we can consider whether it's
worth adding it, and in the right namespace.

There is no exporting of HAVE_INIT_FINI as it is a preprocessor
define. All the user has to do it to include newlib.h and they see it (or
fail to see it). (I think we might have a word-choice difference here.
It's a preprocessor define, and is only of local file scope at
preprocessing time. You can't "export" the variable to another file, it
only comes directly from newlib.h.) But this is unrelated to the primary
point I'm making.
Yes, agreed, it is violating preprocessor namespace.
I'm not arguing just theory. I am pointing out that this changes API
(albeit at the preprocessor level instead of the more usual linkage level)
and we are always very careful when API is changed. If this case is one in
which changing it is OK, fine. We just need to consciously make that
decision; my intent in writing is only that we directly make the choice
instead of falling sideways into it. (You clearly think this one is worth
it. I happen to agree, but that's not that important because it's
generally practice for Corinna or Jeff to OK this class of change.)

i think you got confused by my point. my patch is about the HAVE_INITFINI_ARRAY
macro. i followed up pointing out that newlib also leverages HAVE_INIT_FINI
internally, but doesn't make that state visible externally. hence anyone who
tries to leverage HAVE_INITFINI_ARRAY is already getting an incomplete picture.
preprocessor directives create macros, not variables. i understand that
"exporting" isn't a thing here, and isn't the same as "extern" or other C-
level storage/linkage. i'm referring to general concepts, not to specific
standards language, and i'm being lazy and imprecise as a result. i don't
think we need to get into a pointless semantic debate here.

i understand your points. i disagree that removing this symbol will have any
meaningful impact, and that any code that might actually break deserves any
consideration for using something it shouldn't have in the first place.

also, if it makes you feel better, the yearly newlib release has already been
cut, so this will have ~1 year to bake and people lightly experiment before it
makes it into the next release. i know some folks do nightly builds from the
latest git trees as part of their own tests.
