run-tests: separate exit code when no failed tests but warned ones This can be used by buildbot to set the result "warnings" instead of "failed". [ original upstream message ]

run-tests: introduce 'warned' as test result While running, a test resulting in 'warned' is shown as '~'. Test results with state warned are listed between the skipped and the failed tests. Example: Skipped test-revert-flags.t: missing feature: executable bit Skipped test-inotify-lookup.t: missing feature: inotify extension support Warned test-something.t: output changed Failed test-largefiles.t: output changed Failed test-subrepo.t: output changed # Ran 11 tests, 2 skipped, 1 warned, 2 failed. The test result "warned" will be used in later patches. [ original upstream message ]

run-tests: handle sys.exit in main function [ original upstream message ]

run-tests: remove unnecessary variable initialisation ret is always set before it is used, so remove ret = 0 [ original upstream message ]

tests: killdaemons.py for windows distinguishes access violation and terminated To distinguish between access violaition (process belonging to another user) and a terminated process, PROCESS_QUERY_INFORMATION must be enabled. But TerminateProcess still raises error 5 in both cases. Therefore check before if the process has already terminated. [ original upstream message ]
