* Fix missing branch checks in transcoder why: Symmetry problem. `Blobify()` allowed for encoding degenerate branch vertices while `Deblobify()` rejected decoding wrongly encoded data. * Update memory backend so that it rejects storing bogus vertices. why: Error behaviour made similar to the rocks DB backend. * Make sure that leaf vertex IDs are not repurposed why: This makes it easier to record leaf node changes * Update error return code for next()/right() traversal why: Returning offending vertex ID (besides error code) helps debugging * Update Merkle hasher for deleted nodes why: Not implemented, yet also: Provide cache & backend consistency check functions. This was partly re-implemented from `hashifyCheck()` * Simplify some unit tests * Fix delete function why: Was conceptually wrong
