Aristo resume off line syncing on pre loaded database (#2203)
* Update some docu & messages

* Remove cruft from the ledger modules

* Must not overwrite genesis data on an initialised database

why:
  This will overwrite the global state of the Aristo single state DB.
  Otherwise resuming at the last synced state becomes impossible.

* Provide latest block number from journal

why:
  This relates the global state of the DB directly to the corresponding
  block number.

* Implemented unit test providing DB pre-load and resume

Core db+aristo fixes and tx handling updates (#2164)
* Aristo: Rename journal related sources and functions

why:
  Previously, the naming was hinged on the phrases `fifo`, `filter` etc.
  which reflect the inner workings of cascaded filters. This was
  unfortunate for reading/understanding the source code for actions where
  the focus is the journal as a whole.

* Aristo: Fix buffer overflow (path length truncating error)

* Aristo: Tighten `hikeUp()` stop check, update error code

why:
  Detect dangling vertex links. These are legit with `snap` sync
  processing but not with regular processing.

* Aristo: Raise assert in regular mode `merge()` at a dangling link/edge

why:
  With `snap` sync processing, partial trees are ok and can be amended.
  Not so in regular mode.

  Previously there was only a debug message when a non-legit dangling edge
  was encountered.

* Aristo: Make sure that vertices are copied before modification

why:
  Otherwise vertices from lower layers might also be modified

* Aristo: Fix relaxed mode for validity checker `check()`

* Remove cruft

* Aristo: Update API for transaction handling

details:
+ Split `aristo_tx.nim` into sub-modules
+ Split `forkWith()` into `findTx()` + `forkTx()`
+ Removed `forkTop()`, `forkBase()` (now superseded by new `forkTx()`)

* CoreDb+Aristo: Fix initialiser (missing methods)
