/* A collection of related noderevs tends to be widely redundant (similar
 * paths, predecessor ID matching anothers ID, shared representations etc.)
 * Also, the binary representation of a noderev can be much shorter than
 * the ordinary textual variant.
 *
 * In its serialized form, the svn_fs_x__noderevs_t container extracts
 * most of that redundancy and the run-time representation is also much
 * smaller than sum of the respective svn_fs_x__noderev_t objects.
 *
 * As with other containers, this one has two modes: 'construction', in
 * which you may add data to it, and 'getter' in which there is only r/o
 * access to the data.
