Lots of code in Git's configure.ac doesn't follow the typical formatting,
idioms and best practices for Autoconf input files. Improve the situation.
There are probably many more similar improvements to be done, but trying
to clump all of them in a single change would make it unreviewable, so we
content ourselves with a partial improvement.
This change is just cosmetic, and should cause no semantic change.
The most relevant of the changes introduced by this patch are:
- Do not add trailing '\' characters for line continuation where they
are not truly needed.
- In several (but not all) macro calls, properly quote the arguments.
- Few cosmetic changes in spacing and comments.

On a Solaris 10 system with Solaris make installed as '/usr/xpg4/bin/make',
GNU make installed as '/usr/local/bin/make', and with '/usr/local/bin'
appearing in $PATH *before* '/usr/xpg4/bin', I was seeing errors like this
upon invoking "make all":
Usage : make [ -f makefile ][ -K statefile ]...
make: Fatal error: Unknown option `-C'
This happenes because the Git's Makefile, when running on Solaris,
automatically "sanitizes" $PATH by prepending '/usr/xpg6/bin' and
'/usr/xpg4/bin' to it in order to avoid using non-POSIX /bin/sh from
being used. In the setup described above, however, this has an
unintended consequence of forcing the use of Solaris make in recursive
make invocations -- even if the $(MAKE) macro is being correctly used in
them!
When building without using the autoconf machinery, this can be solved
by overriding $(SANE_TOOL_PATH). Teach the autoconf machinery to also
allow users of ./configure to override it from the command line with a
new --with-sane-tool-path option.

The current configure script uses -lintl if gettext is not found in the C
library, but does so before checking if there is libintl.h available in
the first place, in which case we would later define NO_GETTEXT.
Instead, check for the existence of libintl.h first. Only when libintl.h
exists and libintl is not in libc, ask for -lintl.

Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

In the spirit of v1.5.0.2~21 (Check for PRIuMAX rather than
NO_C99_FORMAT in fast-import.c, 2007-02-20), use PRIuMAX from
git-compat-util.h on all platforms instead of C99-specific formats
like %zu with dangerous fallbacks to %u or %lu.
So now C99-challenged platforms can build git without provoking
warnings or errors from printf, even if pointers do not have the same
size as an int or long.
The need for a fallback PRIuMAX is detected in git-compat-util.h with
"#ifndef PRIuMAX". So while at it, simplify the Makefile and configure
script by eliminating the NO_C99_FORMAT knob altogether.

Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM
and friends.
Quoting autoconf-2.68/NEWS:
** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
AC_RUN_IFELSE now warn if the first argument failed to use
AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file
contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have
a compelling reason why you cannot use AC_LANG_SOURCE but must
avoid the warning.
The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM}
take care to supply the previously computed set of #defines (and
include standard headers if so desired) for preprocessed languages
like C and C++.
In some cases, AC_LANG_PROGRAM is already used but not sufficiently
m4-quoted, so we just need to add another set of [quotes] to prevent
the autoconf warning from being triggered bogusly. Quoting all
arguments (except when calling special macros that need to be expanded
before recursion) is better style, anyway. These and more rules are
described in detail in 'info Autoconf "Programming in M4"'.
No change in the resulting config.mak.autogen after running
./configure intended.

On some platforms (like Solaris) there is a fnmatch, but it doesn't
support the GNU FNM_CASEFOLD extension that's used by the
jj/icase-directory series' fnmatch_icase wrapper.
Change the Makefile so that it's now possible to set
NO_FNMATCH_CASEFOLD=YesPlease on those systems, and add a configure
probe for it.
Unlike the NO_REGEX check we don't add AC_INCLUDES_DEFAULT to our
headers. This is because on a GNU system the definition of
FNM_CASEFOLD in fnmatch.h is guarded by:
#if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 || defined _GNU_SOURCE
One of the headers AC_INCLUDES_DEFAULT includes ends up defining one
of those, so if we'd use it we'd always get
NO_FNMATCH_CASEFOLD=YesPlease on GNU systems, even though they have
FNM_CASEFOLD.
When checking the flags we use:
ifdef NO_FNMATCH
...
else
ifdef NO_FNMATCH_CASEFOLD
...
endif
endif
The "else" so that we don't link against compat/fnmatch/fnmatch.o
twice if both NO_FNMATCH and NO_FNMATCH_CASEFOLD are defined.

The "action" parameters for these two tests were supplied incorrectly for
the way the tests were implemented. The tests check whether a program
which calls hstrerror() or basename() successfully links when -lresolv or
-lgen are used, respectively. A successful linking would result in
NEEDS_RESOLV or NEEDS_LIBGEN being unset, and failure would result in
setting the respective variable.
Aside from that issue, the tests did not handle the case where neither
library was necessary for accessing the functions in question. So solve
both of these issues by re-working the two tests so that their form is like
the NEEDS_SOCKET test which attempts to link with just the c library, and
if it fails then assumes that the additional library is necessary and sets
the appropriate variable.
Also an entry in the config.mak.in file is necessary for the NEEDS_LIBGEN
variable to appear in the config.mak.autogen file with the value assigned
by the configure script. Without it, the generated shell script would
contain a snippet like this:
