If baseFeePerGas is configured to "0x0" in the genesis file, bypass the need for a transaction to have a gas price of >= 7 Wei
Ensure baseFeeFloor is either 0 or >= 7 to avoid integer arithmetic issues.

* Do not require a minimum block height when downloading headers or blocks
Peers could have that header, bacause our internal record about the
status of the peer could not always be up-to-date, so it is better
to avoid setting that constraint when selecting peers to download block
headers.

* Backward Sync is now remembering recent finalized blocks.
When syncing using BWS we now consider finalized blocks reported by consensus layer.
When no finalized block is specified, nothing strange will go on. When Finalized block is specified
But Besu is not aware of any finalized block yet, we will sync as usual until the finalized block is about to get imported.
A new invariant is introduced when importing blocks using BWS.
All imported blocks has to descent from latest finalized block or a TTD block if we did not finalize yet.
* Importing a finalized block updates the information in Besu Mutable Blockchain.
* It is no longer possible to import blocks into the blockchain below a previously finalized block when using BWS
* When a new finalized block gets announced while BWS is in progress and Besu already has it imported, the Mutable Blockchain gets updated, and the chain gets checked for possible pruning
* When trying to import blocks of equal height as newly announced finalized block, then only the new announced finalized block will be possible to import using BWS
* When importing a new block using BWS after finalized, we can now guarantee that the block descends from latest finalized block

Add a new way to synchronize which is X_CHECKPOINT. This mode is experimental so use it at your own risk. This mode allows you to do like a snapsync but starting from a specific checkpoint instead of starting from the genesis.
This checkpoint will be in the genesis configuration of each network. To add the checkpoint mechanism in a network you just have to add the checkpoint section in the genesis.
Currently there is a checkpoint for ropten, goerli and mainnet.
Mainnet on i3.2xlarge <6 hours
Goerli on i3.2xlarge <1 hours
