    LP#1836963: reduce the cost of utility functions, speeding up search
    
    For large org trees, some several seconds are spent testing org visibility.
    The immediate cause is that AppUtils::get_org_tree() does not populate the
    process-local cache with a memcache-cached org tree. That only happens when
    memcache does not have a copy of the org tree. This is obviously a simple
    oversight, which is addressed by making sure any memcache return value
    is pushed into the the process local cache.
    
    Additionally, the visibility check is making heavy use of lots of
    indirection and delegation to utility code, when some slightly smarter code
    could avoid many repeated function calls.  We now supply some local
    utility code to flesh and unflesh the parent_ou field of objects in the
    org tree, allowing us to avoid using find_org() and instead just calling
    parent_ou() when walking "up" the tree.
