Aristo selective read cashing for rocksdb backend (#2145)
* Aristo+Kvt: Better RocksDB profiling

why:
  Providing more detailed information, mainly for `Aristo`

* Aristo: Renamed journal `stats()` to `capacity()`

why:
  `Stats()` was a misnomer

* Aristo: Provide backend read caches for key and vertex IDs

why:
  Dedicated LRU caching for particular types gives a throughput advantage.
  The sizes of the LRU queues used for caching are currently constant
  but might be adjusted at a later time.

* Fix copyright year

Misc updates for full sync (#2140)
* Code cosmetics

* Aristo+Kvt: Fix api wrappers

why:
  Api setup killed the backend descriptor when backend mapping was
  disabled.

* Aristo: Implement masked profiling entries

why:
  Database backend should be listed but not counted in tally

* CoreDb: Simplify backend() methods

why:
  DBMS backend access Was provided very early and over engineered. Now
  there are only two backend machines, one for `Kvt` and the other one
  for an `Mpt` available only via new API.

* CoreDb: Code cleanup regarding descriptor types

* CoreDb: Refactor/redefine `persistent()` methods

why:
  There were `persistent()` methods for any type of caching storage
  facilities `Kvt`, `Mpt`, `Phk`, and `Acc`. Now there is only a single
  `persistent()` method storing all facilities in tandem (similar to
  how transactions work.)

  For non shared `Kvt` tables, there is now an extra storage method
  `saveOffSite()`.

* CoreDb lingo update: `trie` becomes `column`

why:
  Notion of a `trie` is pretty much hidden by the new `CoreDb` api.
  Revealed are sort of database columns for accounts an storage data,
  any of which have an internal state represented by a Keccack hash.
  So a `trie` or `MPT` becomes a `column` and a `rootHash` becomes a
  column state.

* Aristo: rename backend filed `filters` => `journal`

* Update full sync logging

details:
  + Disable eth handler noise while syncing
  + Log journal depth (if available)

* Fix copyright year

* Fix cruft and unwanted imports

Core n lega db update tracer api (#2063)
* Aristo: Remove cruft

* Prettifying profile statistics printing & source code cosmetics

* Aristo/Kvt: API tools update

* CoreDb: Corrections, mostly API related

* CoreDb: Changed the tracer `logDb()` result

why:
  Only the key-value table is used from the logger database

* CoreDb: Update legacy tracer

why:
  The `contains()` directive did not correspond to `0 < get().len`

also:
  Copy `CoreDb` meta settings like `trackLegaApi`, `trackNewApi`, etc. to
  overlay tracer descriptor

* CoreDb: Extend/update tracer API

why:
  Get ready for accommodating `Aristo` tracer

* Fix missing import

why:
  Some CI compilers might have (cached?) a different NIM patch level

* Ditto

Coredb use stackable api for aristo backend (#2060)
* Aristo/Kvt: Provide function hooks APIs

why:
  These APIs can be used for installing tracers, profiling functoinality,
  and other niceties on the databases.

* Aristo: Provide optional API profiling

details:
  It basically is a re-implementation of the `CoreDb` profiling
  implementation

* Kvt: Provide optional API profiling similar to `Aristo`

* CoreDb: Re-implementing profiling using `aristo_profile`

* Ledger: Re-implementing profiling using `aristo_profile`

* CoreDb: Update unit tests for maintainability

* update copyright dates
