forward-port the 0.2.8.7 changelog

      Tor. Closes ticket 19450. Based on a patch from U+039b.

Changes in version 0.2.8.7 - 2016-08-24

  Tor 0.2.8.7 fixes an important bug related to the ReachableAddresses

  option in 0.2.8.6, and replaces a retiring bridge authority. Everyone

  who sets the ReachableAddresses option, and all bridges, are strongly

  encouraged to upgrade.

  o Directory authority changes:

    - The "Tonga" bridge authority has been retired; the new bridge

      authority is "Bifroest". Closes tickets 19728 and 19690.

  o Major bugfixes (client, security):

    - Only use the ReachableAddresses option to restrict the first hop

      in a path. In earlier versions of 0.2.8.x, it would apply to

      every hop in the path, with a possible degradation in anonymity

      for anyone using an uncommon ReachableAddress setting. Fixes bug

      19973; bugfix on 0.2.8.2-alpha.

  o Minor features (geoip):

    - Update geoip and geoip6 to the August 2 2016 Maxmind GeoLite2

      Country database.

  o Minor bugfixes (compilation):

    - Remove an inappropriate "inline" in tortls.c that was causing

      warnings on older versions of GCC. Fixes bug 19903; bugfix

      on 0.2.8.1-alpha.

  o Minor bugfixes (fallback directories):

    - Avoid logging a NULL string pointer when loading fallback

      directory information. Fixes bug 19947; bugfix on 0.2.4.7-alpha

      and 0.2.8.1-alpha. Report and patch by "rubiate".
