Gabriel F. T. Gomes cf2046ec7d float128: Add strfromf128 
Add strfromf128 to stdlib when _Float128 support is enabled.

	* stdio-common/printf-parsemb.c (__parse_one_specmb): Initialize
	spec->info.is_binary128 to zero.
	* stdio-common/printf.h (printf_info): Add new member is_binary128
	to indicate that the number being converted to string is compatible
	with the IEC 60559 binary128 format.
	* stdio-common/printf_fp.c (__printf_fp_l): Add code to deal with
	_Float128 numbers.
	* stdio-common/printf_fphex.c: Include ieee754_float128.h and
	ldbl-128/printf_fphex_macros.h
	(__printf_fphex): Add code to deal with _Float128 numbers.
	* stdio-common/printf_size.c (__printf_size): Likewise.
	* stdio-common/vfprintf.c (process_arg): Initialize member
	info.is_binary128 to zero.
	* stdlib/fpioconst.h (FLT128_MAX_10_EXP_LOG): New macro.
	* stdlib/stdlib.h: Include bits/floatn.h for _Float128 support.
	(strfromf128): New declaration.
	* stdlib/strfrom-skeleton.c (STRFROM): Set member info.is_binary128
	to one.
	* sysdeps/ieee754/float128/Makefile: Add strfromf128.
	* sysdeps/ieee754/float128/Versions: Likewise.
	* sysdeps/ieee754/float128/strfromf128.c: New file.

Gabriel F. T. Gomes 6962682ffe Add strfromd, strfromf, and strfroml functions 
ISO/IEC TS 18661-1 adds several functions in the strfrom family to stdlib.
This patch adds strfromd, strfromf, and strfroml.  This is being done in
preparation for the new floating-point type, float128.  The added functions
convert a floating-point value into a string, with configurable format.
