Extended data Payload specs for the backend. (#1630)
why:
  For the main tree with root vertex ID 1, the leaf nodes hold the
  account data. These accounts may link to sub trees the storage root
  node ID of which must be registered here. There is no reverse key
  lookup on the backend.

note:
  These definitions are experimental. Also, there are some tests missing
  for validating Payload data conversions.

Multi layer architecture 4 aristo db (#1581)
* Cosmetics, renamed fields (eVtx, bVtx) -> (eVid, bVid)

* Multilayered delta architecture for Aristo DB

details:
  Any VertexID or data retrieval needs to go down the rabbit hole and
  fetch/get/manipulate the bottom layer -- even without explicit
  backend.

* Direct reference to backend from top-level layer

why:
  Some services as the vid management needs to be synchronised among all
  layers. So access is optimised.

Experimental MP-trie (#1573)
* Experimental MP-trie

why:
  Deleting records is a infeasible with the current structure

* Added vertex ID recycling management

Todo:
  Provide some unit tests

* DB layout update

why:
  Main news is the separation of `Merkel` hashes into an extra table.

details:
  The code fragments cover conversion between compact MPT records and
  Aristo DB records as well as some rudimentary cache handling for
  the `Merkel` hashes (i.e. the extra table entries.)

todo:
  Add some simple unit test for the descriptor record (currently used
  for vertex ID management, only.)

* Updated vertex ID recycling management

details:
  added simple unit tests (mainly testing ABI)

* docu update
