Backport PR #10191: IOStream: Ignore missing attrs from `dir()`. #6386 In some cases calling `getattr()` on attributes found with `dir()` will fail. This is seen in Issue #6386. The attribute in that issue is `name`, which is not needed for `IOStream` to work correctly. This fix will set the attribute to `None` and move on. Tests were added in `IPython.utils.tests.test_io.py` to catch any regressions.

"""Setup script for IPython.
Under Posix environments it works like a typical setup.py script.
Under Windows, the command sdist is not supported, since IPython
requires utilities which are not available under Windows."""
