    fix(revalidate): Fix data race when validating content bundles.

    So, it turns out we were still falling through to the old revalidate
    everything code after processing a content bundle change list.  Not
    only was this hiding a few bugs with the new code, it caused spurious
    data races in the parallel revalidate everything code.

    Rework changes to make content bundle changes validate as intended and
    thereby avoid the spurious data race.

    perf(startup): Parallelize object processing on startup

    This adds parallelism in two places at system startup.

    The first is when bulk unmarshalling data from the WAL.  The
    max batch size has been increased from 4 megs to 32, and actual
    unmarshalling load is equally divided among the CPUs present on the
    system if the total amount of data being unmarshalled passes a certain

    The second is when validating data when building the datatracker.  The
    data load for parallelization is divided across all CPUs in the same fashion
    as when being bulk unmarshalled, unless the objects in question are
    backed by a RawModel -- trying to parallelize operations on them resulted
    in concurrent map access panics.

    perf(startup): Cache sorted indexes.

    This adds functionality to the Index layer to recognize when we are
    asking for a sorted version of a base index, and caches the result
    for later use if we are.  The cache will be invalidated if anything
    is added, removed, or modified in the base layer of the index.

    To enable this to work properly, Names have been added to all Makers
    where applicable, to give each index a set of unique keys to work with.
