302bb1a3c3 float128: Add wrappers to override ldbl-128 as float128. 
This change defines float128_private.h which contains
macros used to override long double naming conventions
when building a ldbl file.

	(SNANF128): New macro.
	* math/e_sqrtf128.c: New file.
	* math/s_fmaxmag_template.c: Include math_private.h in order to
	make inline expansion of fabs128().
	* math/s_fminmag_template.c: Likewise.

525f803984 Add fmaxmag, fminmag functions. 
TS 18661-1 defines fmaxmag and fminmag functions that return the
argument with maximum / minimum magnitude (acting like fmax / fmin if
the arguments have the same magnitude or either argument is a NaN).
These correspond to the IEEE 754-2008 operations maxNumMag and
minNumMag.  This patch implements these functions for glibc.  They are
implemented with type-generic templates.  Tests are based on those for
fmax and fmin.

Tested for x86_64, x86, mips64 and powerpc.

	* math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)]
	(fmaxmag): New declaration.
