Eric Blake cbd5934b19 warn-on-use: use instead of link-warning 
Each *.in.h file serves two purposes - provide enough self-contained
content to serve as a replacement for the system header regardless of
the user's compiler, and offer the developer the ability to detect any
gnulib modules that might have been inadvertantly excluded.  The
former requires independence from config.h, and routes everything
through a Makefile.am snippet that uses @@ substitution specific to
the modules that were in use, with details learned at configure time.

The latter works by poisoning anything that gnulib did not replace,
but which the developer had natively available, explaining why their
tests passed during development.  Poisoning relies on gcc features,
and requires manual triggering by adding -DGNULIB_POSIXCHECK to
CFLAGS; it assumes that <config.h> is properly included.  In fact, we
do not want to use @@ substitution for HAVE_DECL_* during poisoning,
because the warning is only relevant for the gnulib modules which were
not included, and thus where the m4 macros to set proper @@ values
have not been run.  Furthermore, we only need to poison interfaces
that already have a declaration; if something is not declared, then
the developer wouldn't have been able to link, so their code won't be
using the problematic interface in the first place.

Eric Blake 524d6a2ef5 stdio: warn on suspicious uses 
Using gets is almost ALWAYS wrong (it is extremely rare that you have
full control over stdin).  POSIX 2008 marked it as obsolete, even
though C89 requires it.  Attach a warning to remind developers.  Add
a comment to sprintf explaining why it does not get this treatment.

Improve the warnings for fseek/fseeko (and ftell/ftello), with
comments justifying our position.

Some of our unit tests never use large files, so rather than drag
in a dependency on fseeko, they should be the first compilation
units to use _GL_NO_LARGE_FILES.

* modules/stdio (Depends-on): Add warn-on-use.
(Makefile.am): Provide new substitutions.
* m4/stdio_h.m4 (gl_STDIO_H): Check for inline, ftello, and
fseeko.
* lib/stdio.in.h (gets): Always warn on use.
(fseek, ftell): Adjust when warnings are issued, and honor
_GL_NO_LARGE_FILES as a way to silence the warning.
* tests/test-fpurge.c [!GNULIB_FSEEK]: Use new means to squelch
any warning about large file offsets.

Jim Meyering 47a8dd64ac annotate automake snippets with $(AM_V_GEN) and $(AM_V_at) 
This makes it so packages using automake-1.11's silent-rules option
can print e.g., a single "GEN    configmake.h" line, rather than
the 30+ statements that perform the job.  If you want to see the
actual commands, you can still run "make V=1".
