implement a private state for the uchar.h functions
The C standard is imperative on that: 7.28.1 ... If ps is a null pointer, each function uses its own internal mbstate_t object instead, which is initialized at program startup to the initial conversion state; and these functions are also not supposed to implicitly use the state of the wchar.h functions: ... The implementation behaves as if no library function calls these functions with a null pointer for ps. Previously this resulted in two bugs. - The functions c16rtomb and mbrtoc16 would crash when called with ps set to null. - The function mbrtoc32 used the private state of mbrtowc, which it is not allowed to do.
