Moreover almost all linux ioctl can't be represented by 32bit integer
(i.e. MSB is 1). We need wrap ioctl argument type.

so, if the io is text mode and has ECONV_UNIVERSAL_NEWLINE_DECORATOR
flag, use crlf_newline converter for writing.
this change fixes the problem about the luck of CR up Kernel.p and
Kernel.puts to stdout/stderr on Windows.
