  Fix up checkout file contents checks
  
  This fixes of the file contents checks in checkout to give
  slightly better error messages by directly calling the underlying
  clar assertions so the file and line number of the top level call
  can be reported correctly, and renames the helpers to not start
  with "test_" since that is kind of reserved by clar.
  
  This also enables some of the CRLF tests on all platforms that
  were previously Windows only (by pushing a check of the native
  line endings into the test body).
