* content: fixed data race in IterateUnreferencedBlobs * upload: fixed data race between uploader and estimator * testing: fixed data race in repo/blob/logging test * makefile: run tests on CI/linux/amd64 with -race * robustness: fixed test race * content: fixed data race getContentDataUnlocked that triggers TestParallelWrites - looks scary but in practice very hard to trigger in real life and does not cause data corruption * testing: reduce test complexity under race detector * server: fixed minor race in refreshStatus() * testing: reduced depth of sharedTestDataDir2 * ci: run race detector in separate job * ci: run unit test race detector in parallel to integration tests
