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.
