    Clean-up ill-advised fork of core/cipher/aes.
    
    For reasons which seemed to make sense at the time but of which he has
    long since repented, Joachim forked the core/cipher/aes repository to
    a new core/cipher/aes_speed repository rather than just branching.
    After some discussion, we decided to repair this.
    
    Summary of repair:
    
    1) Create new empty repository, add both core/cipher/aes and
       core/cipher/aes_speed as remotes.
    
    2) Identify commit in core/cipher/aes from which core/cipher/aes_speed
       was forked (determined by log inspection and comparison of the diff
       size between commits in aes/master and aes_speed/master).
    
    3) Splice the trees using a terrifying git command:
    
          git checkout -b master aes_speed/master
    
          git filter-branch \
              --commit-filter 'git commit-tree -S${keyid} "$@"' \
              --parent-filter "sed 's/^\$/-p ${fork_point}/'" \
              master
    
       where ${keyid} is the GPG key ID of the person doing the repair
       work and ${fork_point} is the ID of the commit in core/cipher/aes
       from which core/cipher/aes_speed was forked.
    
    4) Merge the filtered master branch created above to aes/master with
       `-s our` so that the master branch going forward will be the
       content from core/cipher/aes_speed.
