io.c (ioctl_req_t): Type of req argument of ioctl() depend on platform.
Moreover almost all linux ioctl can't be represented by 32bit integer
(i.e. MSB is 1). We need wrap ioctl argument type.
[Bug #5429] [ruby-dev:44589]
io.c (struct ioctl_arg): ditto.
io.c (rb_ioctl): ditto.
test/ruby/test_io.rb (test_ioctl_linux): add a testcase for ioctl
Moreover almost all linux ioctl can't be represented by 32bit integer
(i.e. MSB is 1). We need wrap ioctl argument type.
