If you have a wrapper of IO.open, you may handle mode.
For example on Windows, you may want to add 'b' / OBINARY to given mode.

But some modes has only integer form like O_CLOEXEC, O_EXCL.
If so you need to convert from modestr to oflags

Therefore how about adding a Ruby API version of rb_io_modestr_oflags
