* A whole mess of backup changes

  - the code should be clearer, more organized, commented, and have worthwhile
    variable names now
  - proactive backup=()s now work.  That is, adding a file to a backup array
    does what it should on the upgrade to that package, no longer forcing you to
    wait a full upgrade cycle for it to take effect
* ldconfig was being run twice on an upgrade operation - fixed
* fixed another pm_fprintf/printf output corruption with the progress bars
* refactored some duplicate code for adjusting 'requiredby' lists
* Added config.rpath to .cvsignore
