float128: Include math-finite.h for _Float128

Browse Source 
All the declarations in math-finite.h are macroized by floating-point
type.  This patch includes it for float128 and protects the
declarations of functions that need not be declared for float128.

	* math/math.h: Include bits/math-finite.h for float128.
	(__MATH_DECLARING_FLOATN): Define to control declaration of
	float128 functions.
	* math/bits/math-finite.h (pow10): Do not declare for float128.
	(gamma): Likewise.
	(scalb): Likewise.
