Update: Add f_directory tests then fix problems discovered problems and perform appropriate cleanups.
The "preserve_path_headers" in settings-mocks and settings-tests should be set to "yes".
Add missing dependencies-tests file for any project providing tests.
Remove at_id <= 0 parameter checks because this is already handled by EBADF.
Fix alphabetic ordering of errno returns for f_directory.
I started doing this for f_file as well until I realized how much there is to do.
I won't continue this for f_file because I don't plan on adding tests for f_file for this next release.
The ENOTDIR should return F_directory_not rather than F_directory.
Unable to perform many of the tests because the dynamic linker wrapper is not properlly handling stat() and scandir() as expected.
These tests are commented out, incomplete, and comments are added describing why.
