* add more logging to rrddim fatal incorrect pointer returned from index * increase status file version to 13 * remove reuse of old uuidmap ids * debug info to find leaked refcount * fix strings leak in streaming; count delayed dictionaries * switch rd pointer when rrddim_mem finds the same uuidmap id on a different rrddim * fix the rrdset-name cleanup * cleanup
