s4 torture: RAW-ACL Improvements

- Change RAW-ACLS test suite so each test can be run individually.
- Add verify_sd() and verify_attrib() helper functions.
- Change test_nttrans_create() to work for both files and directories.
- Fix a segfault in test_inheritance() when the test errors out early.
- test_sd_get_set() does not pass against XP or Vista, so it is no longer added
  to the RAW-ACLS test suite.
- Minor fixes to test_inheritance().
- New INHERITFLAGS test, which tests the auto inheritance flags a bit more.
- printf -> torture_comment / torture_warning / torture_result
