math: add portability warnings for classification macros
For interfaces which are defined to exist only as macros, implement
the proper magic needed to warn if the corresponding gnulib module was
not in use. This solution avoids promoting arguments unnecessarily,
to allow reuse in case gnulib ever implements fpclassify, since
fpclassify(1e-40f) is different than fpclassify(1e-40).

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

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

warn-on-use: new module
The goal of GNULIB_POSIXCHECK is to allow a developer on a reasonably
portable system to detect instances where they may have succeeded
because their system is up-to-date, but where compilation would fail
or create a misbehaving application on some other system due to some
portability problem, all without requiring that the developer have
access to other machines. In other words, we want to poison all
interfaces that have a gnulib replacement if the corresponding gnulib
module is not in use. For macros, the solution is undefining the
macro; unfortunately this causes compilation error without many
details as to why, but it is better than nothing. For functions, the
solution is to cause a warning if the function is used.
Previously, the link-warning could poison functions, but only on glibc
systems and with gcc. This module introduces _GL_WARN_ON_USE as a way
of poisoning functions for a few more systems.
Using the gcc __warning__ attribute (added in 4.3.0, early 2008)
rather than using link-warning.h is favorable because:
1) Provides a warning immediately at compile-time. The user does not
have to wait until he links a program.
2) Less use of C macros. Less risk of collision.
3) It's available on more platforms. Depends only on GCC.
4) The formatting of the message is nicer.
There is a minor regression: the gcc attribute is currently not as
powerful as a link warning at detecting uses via function pointers:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42384
However, that style of coding is less frequent.
* modules/warn-on-use: New file.
* build-aux/warn-on-use.h: Likewise.
* m4/warn-on-use.m4: Likewise.
* MODULES.html.sh (Support for building): Mention it.
