Update to 0.34
    
    - open a connection to the bus for every service we're serving, instead of
      using just one for the lot of them, so that we can tell which service a
      client was attempting to contact if it sends a message to our unique
      connection address instead of a well-known name, like dbus-python does
    - tweak the logic for guessing which interface name is right when a request
      doesn't include one, so that it has a better chance of finding the right one
    - increase the initial size of the buffer that we pass to getpwnam_r in the
      pam_oddjob_mkhomedir module (#1198812)
