Don't use NULL for integer arguments

This fixes compiler warnings:

api/baseapi.cpp:1422:49: warning:
 passing NULL to non-pointer argument 6 of
 'int MultiByteToWideChar(UINT, DWORD, LPCCH, int, LPWSTR, int)'
 [-Wconversion-null]
api/baseapi.cpp:1427:54:
 warning: passing NULL to non-pointer argument 6 of
 'int WideCharToMultiByte(UINT, DWORD, LPCWCH, int, LPSTR, int, LPCCH, LPBOOL)'
 [-Wconversion-null]
