fmod, fmodl: Fix computation for large quotients x / y.
* lib/fmod.c: Completely rewritten.
* lib/fmodl.c (fmodl): Use implementation of fmod.c with
USE_LONG_DOUBLE.
* modules/fmod (Depends-on): Add isfinite, signbit, fabs, frexp, ldexp,
isnand. Remove fma.
* modules/fmodl (Depends-on): Add float, isfinite, signbit, fabsl,
frexpl, ldexpl, isnanl. Remove fma.
* m4/fmod.m4 (gl_FUNC_FMOD): Update computation of FMOD_LIBM.

fmod-ieee: Work around test failures on OSF/1, mingw.
* m4/fmod-ieee.m4: New file.
* m4/fmod.m4 (gl_FUNC_FMOD): If gl_FUNC_FMOD_IEEE is present, test
whether fmod works with zero arguments. Replace it if not.
* lib/math.in.h (fmod): New declaration.
* lib/fmod.c: New file.
* m4/math_h.m4 (gl_MATH_H): Test whether fmod is declared.
(gl_MATH_H_DEFAULTS): Initialize GNULIB_FMOD, REPLACE_FMOD.
* modules/math (Makefile.am): Substitute GNULIB_FMOD, REPLACE_FMOD.
* modules/fmod (Files): Add lib/fmod.c.
(Depends-on): Add math, isinf, trunc, fma.
(configure.ac): Arrange to compile lib/fmod.c if needed.
* modules/fmod-ieee (Files): Add m4/fmod-ieee.m4, m4/minus-zero.m4,
m4/signbit.m4.
(configure.ac): Invoke gl_FUNC_FMOD_IEEE.
* tests/test-math-c++.cc: Check the declaration of fmod.
* doc/posix-functions/fmod.texi: Mention the fmod-ieee module.
