forward-port the 0.1.1.23 changelog.

    - Add TestVia config option to the man page.

Changes in version 0.1.1.23 - 2006-07-30

  o Major bugfixes:

    - Fast Tor servers, especially exit nodes, were triggering asserts

      due to a bug in handling the list of pending DNS resolves. Some

      bugs still remain here; we're hunting them.

    - Entry guards could crash clients by sending unexpected input.

    - More fixes on reachability testing: if you find yourself reachable,

      then don't ever make any client requests (so you stop predicting

      circuits), then hup or have your clock jump, then later your IP

      changes, you won't think circuits are working, so you won't try to

      test reachability, so you won't publish.

  o Minor bugfixes:

    - Avoid a crash if the controller does a resetconf firewallports

      and then a setconf fascistfirewall=1.

    - Avoid an integer underflow when the dir authority decides whether

      a router is stable: we might wrongly label it stable, and compute

      a slightly wrong median stability, when a descriptor is published

      later than now.

    - Fix a place where we might trigger an assert if we can't build our

      own server descriptor yet.

Changes in version 0.1.1.22 - 2006-07-05

  o Major bugfixes:

    - Fix a big bug that was causing servers to not find themselves
