repo: repo isolation, do not pass on repo.ui for creating new repos A repo should not get the configuration from an other repo, so create it with the global configuration in repo.baseui. This is done too when recreating a repo. The repo configuration is reread anyway. And now deleted repo configuration does not persist. [ orginal upstream message ]

run-tests: introduce --random for running tests in random error This is convenient when investigating failures one by one to avoid running the same fixed tests first every time. [ original upstream message ]
