Message 124501 - Python tracker

Thanks for the update! Three more comments:

* the new constants doc should also get a versionadded

* faccessat should check for EBADF, EINVAL and ENOTDIR and raise an error if they are returned, since these are input errors 

  Or, alternately, a range of errnos should be whitelisted for both access and faccessat.

  However, this problem should be handled in a separate issue, I've opened #10758 for that.

* The octal modes in docstrings and docs should be specified in Python 3 octal syntax, e.g. 0o777.
