snippet/c++defs: fix real-floating arg functions in C++ mode Also, define isfinite, isinf, isnan, signbit in the gnulib namespace instead of in the global namespace. * build-aux/snippet/c++defs.h (_GL_BEGIN_NAMESPACE) (_GL_END_NAMESPACE): New. * lib/math.in.h (_GL_MATH_CXX_REAL_FLOATING_DECL_2): Use them. (isfinite, isinf, isnan, signbit) [__cplusplus && GNULIB_NAMESPACE]: Define them in the GNULIB_NAMESPACE namespace instead of in the global namespace. * tests/test-math-c++.cc: Check that the isfinite, isinf, isnan, signbit overloads exist in the GNULIB_NAMESPACE namespace, instead of in the global namespace.
