This is a partial sync of the CRT library with wcsrtombs_l and _mbstowcs_l functions from WINE. The _wctomb_s_l implementation of WINE which is used by _wctomb_s, _wctomb_l and wctomb brings failed results of the wctomb unit testcase and at the same time it crashes the whole testcase after. Therefore I will not address the wctomb function for the moment being.
