This commit: * Fixes bad handling of 'stop iteration' (by adding a status flag, so that we can actually stop in helper functions too, and jumping to a finalize label instead of raw return, to allow propper clean up). * Adds optional recursion into 'ID tree' - callback can also decide to exclude current id_pp from recursion. Note that this implies 'readonly', modifying IDs while recursing is not something we want to support! * Changes callback signature/expected behavior: return behavior is now handled through flags, and 'parent' ID of id_pp is also passed (since it may not always be root id anymore).
