Keep IEEE code paths only:
* removed SVID, XOPEN, POSIX code paths from everywhere.
* deleted s_lib_version.c, as version is only useful if multiple
standards are supported.
* deleted k_standard.c, as it handles non-IEEE exception cases only.
* renamed the e_{acos,asin,atan2,exp,fmod,log,pow,sqrt}.c sources as
s_.*, dropped the __ieee754_ prefix from the names of the
appropriate functions therein, and deleted the
w_{acos,asin,atan2,exp,fmod,log,pow,sqrt}.c wrapper code.
Keep C99 declaration variants only:
* removed old C-style function declaration variants.
* removed data declaration variants where const qualifier was not
used.
Clean unused sources/functions:
* removed s_{rint,significand,tanh}.c and the appropriate functions
defined therein.
