Use strbufs and strings instead of interned strings for values of rev, dump, and node fields that happen to be strings. After this change, the only remaining string_pool use is for paths in the repo_tree API and internals. Functional change: treat an empty author, UUID, or URL as none at all. So for example, in repos where the first revision has an empty svn:author property, the first rev will be treated as by "nobody" rather than by a person with empty name and email address created by prepending an @ sign to the repository UUID.
