o Minor bugfixes (crypto error-handling):
    - If crypto_early_init fails, a typo in a return value from tor_init
      means that tor_main continues running, rather than returning
      an error value.
      Fixes bug 16360; bugfix on d3fb846d8c98 in 0.2.5.2-alpha,
      introduced when implementing #4900.
