speed up refresh_index() by utilizing preload_index()

Browse Source 
Speed up refresh_index() by utilizing preload_index() to do most of the work
spread across multiple threads.  This works because most cache entries will
get marked CE_UPTODATE so that refresh_cache_ent() can bail out early when
called from within refresh_index().

On a Windows repo with ~200K files, this drops refresh times from 6.64
seconds to 2.87 seconds for a savings of 57%.
