1.2.1-rc2

• The behaviour of compactor is changed when an interrupt (SIGINT, SIGTERM)
  is received e.g. when the service is restarted or a user enters ^C.
  Previously all of the in progress C-DNS compression was aborted and all of
  the in progress output files (compressed and uncompressed) were removed. Now
  the .raw uncompressed output file is left on disk so it can be manually
  recovered (i.e. renamed and compressed). Users will now need to choose how to
  managed these uncompressed files. Behaviour on SIGHUP (re-reading of config
  file without affecting any in progress compression) is unchanged.
• Additional default logging is added of the specific signal received by
  compactor, when file rotation occurs and when compression is aborted.
• New log-file-handing option to log low level details of file
  processing on file rotation and compression. This aids with debugging of file
  processing problems and measurement of C-DNS file compression times.
• Text added in the documentation to clarify time patterns are needed in file
  output patterns for filename based file rotation to occur (based on the
  rotation-period option).
• Fix a bug relating to compactor start_time handling introduced in rc1.
