Import correctly working strtold from David M. Gay.
* libc/stdlib/Makefile.am (GENERAL_SOURCES): Add strtodg.c and
strtorx.c.
* libc/stdlib/Makefile.in: Regenerate.
* libc/stdlib/strtodg.c: New file implementing generic string to long
double conversion.
* libc/stdlib/strtorx.c: New file, implementing IEEE format string to
long double conversion.
* libc/stdlib/mprec.h (_strtodg_r): Declare.
(_strtorx_r): Declare.
* libc/stdlib/gdtoa.h (__UShort): Define.
* libc/stdlib/strtold.c (__flt_rounds): Define for i386 and x86_64
target.
(FLT_ROUNDS): Define, as 0 on platforms missing a __flt_rounds
function.
(_strtold_r): Converted from strtold. Call _strtorx_r on targets
supporting distinct long doubles.
(strtold): Just call _strtold_r.
* libc/include/stdlib.h (_strtold_r): Declare.
* libc/stdlib/ldtoa.c (_strtold): Comment out. Explain why.
* libc/stdio/vfscanf.c (__SVFSCANF_R): Call _strtold_r instead of
_strtold.
* libc/machine/powerpc/vfscanf.c (__svfscanf_r): Ditto.
* common.din (strtold): Drop redirection to _strtold.
