Update to 0.69
    
    - tweak how we decide whether we're on the master or a minion when we're
      told to use certmaster as a CA
    - clean up one of the tests so that it doesn't have to work around internal
      logging producing duplicate messages
    - when logging errors while setting up to contact xmlrpc servers, explicitly
      note that the error is client-side
    - don't abort() due to incorrect locking when an attempt to save an issued
      certificate to the designated location fails (part of #1032760/#1033333,
      ticket #22)
    - when reading an issued certificate from an enrollment helper, ignore
      noise before or after the certificate itself (more of #1032760/1033333,
      ticket #22)
    - run subprocesses in a cleaned-up environment (more of #1032760/1033333,
      ticket #22)
    - clear the ca-error that we saved when we had an error talking to the CA if we
      subsequently succeed in talking to the CA
    - various other static-analysis fixes
