Update to 0.45.0
  Fix rare failures in "Clean" target. Thanks to David Holland!

  New configuration variable SEND_REPORT_FIRST was introduced.

  Boolean variables MASTER_MODE, CROSS_COMPILE, SEND_REPORT_FIRST
  accepts values true|yes|1 for logical TRUE and false|no|0 for
  logical FALSE. This may fix some hacks in single node setups.

  During upload rsync may unexpectedly fail due to connection
  failure. In order to resolve this problem, upload may be repeated
  several times. The following variables were introduced for this
  purpose: UPLOAD_PKGS_ATTEMPTS, UPLOAD_PKGS_PAUSE,
  UPLOAD_LOGS_ATTEMPTS, UPLOAD_LOGS_PAUSE.

  Progress messages now better illustrates internal structure of
  the build process.

  Option -a was added to distbb(1) in order to build updates for
  quarter releases more efficiently.

  stage_checks:
    - double underline in "checks" filename means _ in the report
      text, single underline means space.
    - one more check for broken pkg_summary (REQUIRES field).  It
      checks for libraries under /tmp, /home, /srv and /work
      directories.

  stage_upload_logs:
    - huge pkg_enriched_summary.txt is not uploaded
