Remove changes files for items that will appear in 0.3.4.4-rc

  o Minor bugfixes (compilation):

    - Refrain from compiling unit testing related object files

      when --disable-unittests is set to configure script.

      Fixes bug 24891; bugfix on 0.2.5.1-alpha.

  o Minor bugfixes (onion services):

    - Recompute some consensus information after clock skews or when we

      transition from a non-live consensus to a live consensus. We do this to

      avoid having an outdated state which could impact next-generation onion

      services. Fixes bug 24977; bugfix on 0.3.2.1-alpha.

  o Minor features (relay, diagnostic):

    - Add several checks to detect whether Tor relays are uploading their

      descriptors without specifying why they regenerated. Diagnostic for

      ticket 25686.

  o Minor bugfixes (testing):

    - Instead of trying to  read the geoip configuration files from within the

      unit tests, instead create our own ersatz files with just enough

      geoip data in the format we expect. Trying to read from the source

      directory created problems on Windows with mingw, where the

      build system's paths are not the same as the platform's paths.

      Fixes bug 25787; bugfix on 0.3.4.1-alpha.

  o Minor bugfixes (relay):

     - Relays now correctly block attempts to re-extend to the previous

       relay by Ed25519 identity. Previously they would warn in this case,

       but not actually reject the attempt. Fixes bug 26158; bugfix on

       0.3.0.1-alpha.
