o Minor bugfixes:

    - Increase the maximum length of microdescriptor we are willing to
      generate from 1K to 2K. Occasionally this is needed for routers
      with complex policies or family declarations. Partial fix for
      bug 6404; fix on 0.2.2.6-alpha.

    - Authorities no longer include any router in their
      microdescriptor consensuses for which they couldn't generate or
      agree on a microdescriptor.  Partial fix for bug 6404; fix on
      0.2.2.6-alpha.

    - Move log message when unable to find a microdesc in a
      routerstatus entry to parse time. Previously we'd spam this
      warning every time we tried to figure out which microdescriptors
      to download. Partial fix for bug 6404; fix on 0.2.3.18-rc.
