Block header download beacon to era1 (#2601) * Block header download starting at Beacon down to Era1 details: The header download implementation is intended to be completed to a full sync facility. Downloaded block headers are stored in a `CoreDb` table. Later on they should be fetched, complemented by a block body, executed/imported, and deleted from the table. The Era1 repository may be partial or missing. Era1 headers are neither downloaded nor stored on the `CoreDb` table. Headers are downloaded top down (largest block number first) using the hash of the block header by one peer. Other peers fetch headers opportunistically using block numbers Observed download times for 14m `MainNet` headers varies between 30min and 1h (Era1 size truncated to 66m blocks.), full download 52min (anectdotal.) The number of peers downloading concurrently is crucial here. * Activate `flare` by command line option * Fix copyright year

* Update/resolve code fragments which are tagged FIXME
Clean up modules in sync folder (#2670) * Dissolve legacy `sync/types.nim` into `*/eth/eth_types.nim` * Flare sync: Simplify scheduler and remove `runSingle()` method why: `runSingle()` is not used anymore (main purpose was for negotiating best headers in legacy full sync.) Also, `runMulti()` was renamed `runPeer()` * Flare sync: Move `chain` field from `sync_desc` -> `worker_desc` * Flare sync: Remove handler descriptor lateral reference why: Not used anymore. It enabled to turn on/off eth handler activity with regards to the sync state, i.e.from with in the sync worker. * Flare sync: Update `Hash256` and other deprecated `std/eth` symbols * Protocols: Update `Hash256` and other deprecated `std/eth` symbols * Eth handler: Update `Hash256` and other deprecated `std/eth` symbols * Update flare TODO * Remove redundant `sync/type` import why: The import module `type` has been removed * Remove duplicate implementation

* Update docu:
Rename flare as beacon (#2680) * Remove `--sync-mode` option from nimbus config why: Currently there is only one sync mode available. * Rename `flare` -> `beacon`, but not base module folder and nim source why: The name `flare` was used do designate an alternative `beacon` mode that. Leaving the base folder and source as-is for a moment, makes it easier to read change diffs. * Rename `flare` base module folder and nim source: `flare` -> `beacon`
