Subject: [ruby-core:69554] [Ruby trunk - Feature #11253]	rb_io_modestr_oflags for Ruby API

Issue #11253 has been updated by Akira Tanaka.


This issue is discussed at DevelopersMeeting20150612Japan.

We found "flags" keyword argument would be better for the intent.

```
open(filename, "w", flags: File::EXCL)
open(filename, "w", flags: File::SHARE_DELETE)
```

The argument will be bitwise-ORed to oflag for open system call.

If a wrapper of open method want to add flags, it can add flags using integer.

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
