Merge the prefix and references tables.

This makes the UnlinkedLibrary type go away, which means that we no
longer have any unlinked summary data which is spread across the
compilation units constituting a library.  That in turn means that we

case where a change to URI resolution affects the relationship between a
library and its parts.
