Fixes #2502 by creating a "special" placeholder that's always a zero-weight child of the root.  This is the new default dependency.  As a result, resources with unknown initial priority will briefly get low priority instead of briefly getting high priority and disrupting actual high-priority resources.

If we're going to have a zero-weighted placeholder, it makes sense to allow zero-weighting in general, so I added that at the same time.  Also filled a few editorial gaps in the priority section (mostly concepts assumed from H2 that aren't explicitly stated) since I noticed them while working on this.  Can separate those out if this doesn't get traction.
