 Some tests are written such that they do intermediate cleanups between
 multiple internal sub-tests for varying reasons, and so use those cleanup
 functions as part of their testing.  The function _cleanup_test_img
 effectively calls all the other functions I listed, so they are really all
 required for the tests, if they choose to call _cleanup_test_img.

And for 'check' to tear everything down to a clean state, it also needs to
use the cleanup functions for everything that is not just a file/directory.
