The proposed patch adds the members parameter for TarFile.list() with the same meaning as in TarFile.extractall(). This is needed for implementing the tar command utility which allows filtering and transforming an output (e.g. output numerical ids instead names for owner/group).

An alternative approach is to add the filter parameter (as in TarFile.add()) to both TarFile.list() and TarFile.extractall().

See bpo-21550 for example.

Added a test. Make the members parameter keyword-only.

If there are no objections I'll commit the patch soon.
