    perf(index): Track primary keys in the indexes

    When dealing with large indexes, having to recalculate Key() quickly
    adds a significant amount CPU and memory pressure for several object
    categories that also make our largest indexes.

    To alleviate this CPU and memory pressure, have the indexes also keep
    track of their primary keys, and use them wherever it is reasonable
    instead of recalculating Key() over and over.

    Along the way, fix a few other issues:

    * Optimize object removal from indexes both in the request tracker and
      in the main index code.

    * Don't make deep copies of objects we just deleted when publishing

    * Add dedicated Counts function to RequestTracker, and modify the
      frontend to use it.  This path avoids taking locks on each
      individual object being listed.

    * Content pack loading will now notice when you trye to load an object
      that has no primary key, and complain mightly about it.

    * Turned a couple more paired mutex lock/unlock operations into
      thunking function.

    * Fix a few reporting bugs in the bulk job purge reporting code.

    * Fix testing-specific handling of ABRT
