specific narg length calculation.
* test/ruby/test_io.rb (test_ioctl_linux2): add new test for old and
unstructured ioctl.

On Linux some constants for ioctl(2) doesn't include the size of
its return value and 16bit value; for example FIONREAD 0x541B.
Moreover the manual, ioctl_list(2), says "Note that the size
bits are very unreliable: in lots of cases they are wrong,
either because of buggy macros using sizeof(sizeof(struct)),
or because of legacy values."
So we shouldn't use it.

available (for Windows).
* win32/win32.c (fcntl): on F_DUPFD, determine the inheritance of the
new handle by O_NOINHERIT flag of original fd.

fixed the failure of TestArgf#test_textmode introduced at r33662.

It may change string value meaning if the value is string.
(e.g. MacOS X has F_GETPATH ioctl)
* io.c (rb_fcntl): ditto.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@33717 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
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
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@33716 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* io.c (rb_io_ctl): don't use ioctl specific length check
if caller is fcntl.

in 1.9.3 or later.

ECONV_NEWLINE_DECORATOR_WRITE_MASK): new macro.
* io.c (rb_io_extract_modeenc, pipe_open, prep_stdio, argf_next_argv):
set TEXTMODE_NEWLINE_DECORATOR_ON_WRITE for textmode on creating IO
if the flag is available.
* io.c (make_writeconv): drop decorators for reading.
* io.c (make_readconv): drop decorators for writing.
* io.c (do_writeconv): existing writeconv is not the condition to raise
ArgumentError. should check textmode or not.
* test/ruby/test_io_m17n.rb
(TestIO_M17N#test_{cr,lf,crlf}_decorator_on_stdout): test above
changes.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@33662 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* io.c (rb_io_flush, rb_io_rewind): fsync() here.
these changes reduces fsync() calls to improve performance.

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.
