OSError when moving configuration file

[Hnasar]

1. Why are you moving something that adheres to http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html elsewhere???? I want fewer things cluttering up my home directory, not more! Really. I am disappoint.
2. use shutil.move
3. my ~/.config/ is a symlink to a different filesystem than my ~/

    If you suspect this is an IPython bug, please report it at:
        https://github.com/ipython/ipython/issues
    or send an email to the mailing list at ipython-dev@scipy.org

    You can print a more detailed traceback right now with "%tb", or use "%debug"
    to interactively debug it.

    Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
        c.Application.verbose_crash=True

1. No it does not adhere to it, as it stores cached files and other stuff that do not comply to the standard.

The rational was that the logic to store the IPython config was alway wrong somewhere, and too complicated, so we removed the platform specific logic. Then packager are responsible to make it coherent with their platform to be XDG compliant or not.

2 . I suspect shutils.move was not use because of windows problem, but we can check.

Pull request welcome, though I'm not sure how to test it.

Cf #4457 for background.

We don't encourage packagers to change it, though, because then users
wouldn't find their files where the docs say to look.

We switched back to ~/.ipython to make it simple to explain where those
files are for all platforms. Also, as Matthias said, we were never really
following the xdg spec properly anyway, because we mix config files and
application data.

should be fixed by #5917.
