Snap accounts bulk import preparer (#1183)
* Provided common scheduler API, applied to `full` sync

* Use hexary trie as storage for proofs_db records

also:
 + Store metadata with account for keeping track of account state
 + add iterator over accounts

* Common scheduler API applied to `snap` sync

* Prepare for accounts bulk import

details:
+ Added some ad-hoc checks for proving accounts data received from the
  snap/1 (will be replaced by proper database version when ready)
+ Added code that dumps some of the received snap/1 data into a file
  (turned of by default, see `worker_desc.nim`)

Clique snapshots reorg (#1169)
* Add persistent snapshot size logging

why:
  Suspecting too much space used

snapshot statistic:
  [..]
  blockNumber=2214912 nSnaps=2236 snapsTotal=1.14m
  blockNumber=2215936 nSnaps=2237 snapsTotal=1.14m
  [..]
  Persisting blocks fromBlock=2216449 toBlock=2216640

* Replace legacy `lru_cache` by `keyed_queue`

why:
  `keyed_queue` generalises `lru_cache`

snapshot statistic:
  [..]
  blockNumber=2234368 nSnaps=2259 snapsTotal=1.15m
  blockNumber=2235392 nSnaps=2260 snapsTotal=1.15m

* Increase persistent snapshot storage interval by 300%

snapshot statistic:

* Cull legacy debugging environment for clique

why:
  Chronicles provides a better choice (when properly set up)

Sync update to work with sepolia reorgs (#1168)
* Error return in `persistBlocks()` on initial `VmState` roblem

why:
  previously threw an exception

* Updated sync mode option

why:
 using enum rather than bool => space for more

* Added sync mode `full`, re-factued legacy sync

also:
  rebased

* Fix typo (crashes `pesistBlocks()` otherwise)

also:
  rebase to master

* Reduce log ticker noise by suppressing duplicate messages

* Clarify staged queue overflow handling

why:
  backtrack/re-org mode in `stageItem()` should be detected by both,
  the global indicator or the work item where it might have moved into.

also:
  rebased

Store proved snap accounts (#1145)
* Relocated `IntervalSets` to nim-stew repo

* Accumulate accounts on temporary kv-DB

why:
  Explore the data as returned from snap/1. Will be converted to a
  `eth/db` next.

details:
  Verify and accumulate per/state-root accounts downloaded via snap.

also:
  Some unit tests

* Replace `Table` by `TrieDatabaseRef` for accounts accumulator

* update ticker statistics

details:
  mean/variance based counter update

* allow persistent db for proved accounts

* rebase, and globally activate unit test

* fix statistics

Updated account scheduler (#1124)
* Using `IntervalSet` type data for `LeafRange`

* Updated log ticker

* Update to `eth67`

details:
  Disabled by default, use `ENABLE_LEGACY_ETH66=0` to enable
  No support for `Get/NodeData` dialogue via eth, anymore

* Dissolved fetch/common.nim

details;
  the log/ticker part becomes ticker.nim
  the interval range management is merged into fetch.nim

* Updated account scheduler

why:
  The previous scheduler fetched each account once (for different state
  roots.) The updated scheduler re-calibrates after a change of the state
  root and potentially (until told otherwise) fetches all possible
  accounts.

* Fix `high(P)` fringe cases in `IntervalSet` handling

why:
  The `high(P)` value for a point type `P` cannot be represented with
  half open intervals `[a,b)` for a,b points of `P`. So this single value
  needs extra treatment which was slightly wrong.

* Updated docu/comments

also:
  rebased

* Update scheduler

details:
  Change the `pivot` management when creating new accounts lists. It is
  strictly increasing (and wrapping around) depending on last updated
  accounts list.
