some more changelog cleanups

    - When we are using bridges and we had a network connectivity

      problem, only retry connecting to our currently configured

      bridges, not all bridges we know about and remember using. Fixes

      bug 14216; bugfix on tor-0.2.2.17-alpha. Patch from arma.

      bug 14216; bugfix on 0.2.2.17-alpha.

  o Minor bugfixes (client, IPV6):

  o Minor bugfixes (client, IPv6):

    - Reject socks requests to literal IPv6 addresses when IPv6Traffic

      flag is not set; and not because the NoIPv4Traffic flag was set.

      Previously we'd looked at the NoIPv4Traffic flag for both types of

      literal addresses. Fixes bug 14280; bugfix on 0.2.4.7-alpha.

  o Minor bugfixes (compilation):

    - Build without warnings with the stock OpenSSL srtp.h header, which

      has a duplicate declaration of SSL_get_selected_srtp_profile().

      Fixes bug 14220; this is OpenSSL's bug, not ours.

    - The address of an array in the middle of a structure will always

      be non-NULL. clang recognises this and complains. Disable the

      tautologous and redundant check to silence this warning. Fixes bug

      14001; bugfix on 0.2.1.2-alpha.

    - Compile correctly with (unreleased) OpenSSL 1.1.0 headers.

      Addresses ticket 14188.

    - Avoid warnings when building with systemd 209 or later. Fixes bug

      14072; bugfix on 0.2.6.2-alpha. Patch from "h.venev".

    - Compile correctly with (unreleased) OpenSSL 1.1.0 headers.

      Addresses ticket 14188.

    - Build without warnings with the stock OpenSSL srtp.h header, which

      has a duplicate declaration of SSL_get_selected_srtp_profile().

      Fixes bug 14220; this is OpenSSL's bug, not ours.

    - Remove the --disable-threads configure option again. It was

      accidentally partially reintroduced in 29ac883606d6d. Fixes bug

      14819; bugfix on 0.2.6.2-alpha.

  o Minor bugfixes (controller):

    - Add a code for the END_CIRC_REASON_IP_NOW_REDUNDANT circuit close

      reason. Fixes bug 14207; bugfix on 0.2.6.2-alpha.

    - Avoid crashing on a malformed EXTENDCIRCUIT command. Fixes bug

      14116; bugfix on 0.2.2.9-alpha.

    - Report "down" in response to the "GETINFO entry-guards" command

      when relays are down with an unreachable_since value. Previously,

      we would report "up". Fixes bug 14184; bugfix on 0.1.2.2-alpha.

    - Avoid crashing on a malformed EXTENDCIRCUIT command. Fixes bug

      14116; bugfix on 0.2.2.9-alpha.

    - Add a code for the END_CIRC_REASON_IP_NOW_REDUNDANT circuit close

      reason. Fixes bug 14207; bugfix on 0.2.6.2-alpha.

  o Minor bugfixes (directory authority):

    - Allow directory authorities to fetch more data from one another if

      they find themselves missing lots of votes. Previously, they had

      been bumping against the 10 MB queued data limit. Fixes bug 14261;

      bugfix on 0.1.2.5-alpha.

    - Enlarge the buffer to read bw-auth generated files to avoid an

    - Enlarge the buffer to read bwauth generated files to avoid an

      issue when parsing the file in dirserv_read_measured_bandwidths().

      Fixes bug 14125; bugfix on 0.2.2.1-alpha.

      on 0.2.3.11-alpha.

  o Minor bugfixes (hidden services):

    - Close the introduction circuit when we have no, more usable intro

      points, instead of waiting for it to time out. This also make sure

      no extra HS descriptor fetch is triggered. Fixes bug 14224; bugfix

      on 0.0.6.

    - Close the introduction circuit when we have no more usable intro

      points, instead of waiting for it to time out. This also ensures

      that no follow-up HS descriptor fetch is triggered when the circuit

      eventually times out. Fixes bug 14224; bugfix on 0.0.6.

    - When fetching a hidden service descriptor for a down service that

      we recently up, do not keep refetching until we try the same

      was recently up, do not keep refetching until we try the same

      replica twice in a row. Fixes bug 14219; bugfix on 0.2.0.10-alpha.

    - Successfully launch Tor with a nonexistent hidden service

      directory. Our fix for bug 13942 didn't catch this case. Fixes bug

    - When deciding whether the consensus lists any exit nodes, count

      the number listed in the consensus, not the number we have

      descriptors for. Fixes part of bug 14918; bugfix on 0.2.6.2-alpha.

    - When deciding whether we have any exit nodes, only process

    - When deciding whether we have any exit nodes, only examine

      ExitNodes when the ExitNodes option is actually set. Fixes part of

      bug 14918; bugfix on 0.2.6.2-alpha.

    - Get rid of redundant and possibly scary warnings that we are

      ntor onion key. Closes ticket 9635.

  o Removed features:

    - To avoid confusion with the 'ExitRelay' option, 'ExitNode' is no

      longer silently accepted as an alias for 'ExitNodes'.

    - To avoid confusion with the "ExitRelay" option, "ExitNode" is no

      longer silently accepted as an alias for "ExitNodes".

    - The --enable-mempool and --enable-buf-freelists options, which

      were originally created to work around bad malloc implementations,

      no longer exist. They were off-by-default in 0.2.5. Closes
