 [patch 1/2] fixes compilation / linking errors when using
 -DTRIO_MINIMAL:

triostr.h
trio_to_float() definition was required but missing.

trionan.[ch]
Using the combination of TRIO_PRIVATE_NAN and TRIO_INLINE
resulted in static inline and the linker complaining
that c99_fpclassify_and_signbit didn't exist (debian stretch/gcc/x86).
This may be also the case of all the other functions covered
by TRIO_FUNC_FPCLASSIFY_AND_SIGNBIT.

Solved by changing those functions to use TRIO_INLINE_NAN and
assigning it the value of INLINE only when not using -DTRIO_MINIMAL

 [patch 2/2] simplify definition of c99_fpclassify_and_signbit to fix
 building with LTO

With C99 the inline keyword needs "static" as well if the function is defined
in only one translation unit.

See https://stackoverflow.com/questions/6312597/is-inline-without-static-or-extern-ever-useful-in-c99
