Move fenv.h soft-float inlines from fenv_private.h to include/fenv.h.

<fenv_private.h> has inline versions of various <fenv.h> functions, and their __fe* variants, for systems (generally soft-float) without support for floating-point exceptions, rounding modes or both. Having these inlines in a separate header introduces a risk of a source file including <fenv.h> and compiling OK on x86_64, but failing to compile (because the feraiseexcept inline is actually a macro that discards its argument, to avoid the need for #ifdef FE_INVALID conditionals), or not being properly optimized, on systems without the exceptions and rounding modes support (when these inlines were in math_private.h, we had a few cases where this broke the build because there was no obvious reason for a file to need math_private.h and it didn't need that header on x86_64). By moving those inlines to include/fenv.h, this risk can be avoided, and fenv_private.h becomes more clearly defined as specifically the header for the internal libc_fe* and SET_RESTORE_ROUND* interfaces. This patch makes that move, removing fenv_private.h includes that are no longer needed (or replacing them by fenv.h includes in a few cases that didn't already have such an include). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/fenv_private.h [FE_ALL_EXCEPT == 0]: Move this code ....
