TODO: clear unused payloads after a certain time

Just want to say this. The generated data is basically block. Accumulate the blocks non-stop is very bad.
Do we have any guarantee that when can we clean some cached blocks from the consensus layer?

Previously I enabled the "transition" in this catalyst package by default, so that all the block creation via catalyst API are using the new rules.
But now we pass the merger into the consensus engine, engine = beacon.New(b.InnerEngine(), eth.Merger()). So that it can happen:
for the first block creation, the TTDReached is still false, block is created with old rule.

The results here can lie a bit. The last of the Pow-headers will be fed as the 'ancestor' to the first PoS block. So the PoS block can be deemed 'valid', even if the parent block is later found to be invalid.
So the results can be [valid, valid, valid.. invalid, pos:valid, pos:valid..].
Might not matter 🤷

Hehe, it's interesting! Maybe we can invalidate all the children in case one parent header is invalid. Or we can choose to add this scenario to comment if we think in practice it's impossible?

AFAIK the same can happen even now in ethash. I can make the middle header invalid, it will still leave the headers after it potentially valid since we're evaluating each header individually from the rest.

This commit updates the code to the new spec, moving payloadId into
it's own object. It also fixes an issue with finalizing an empty blockhash.
It also properly sets the basefee

Should we also use IsTTDReached to distinguish pow headers and pos headers?

I tried to implement this change, but it fails in different places.
The biggest one is during VerifyHeaders, the TD of the last parenthash is not in the db, thus verification of it will fail.
During Author we don't have access to the chain reader.
Also the GenerateChain which is used throughout the tests is very opinionated about this as it uses a fakeChainReader which has no idea about the td. Hacking it in is not super easy

nitpick, can ignore it right now. The Merger object I think can be moved to core package since it's irrelevant with consensus anymore.
It's totally fine to leave it here, we can do it in the following PR.
| inserted []numberHash // Ephemeral lookup of number/hash for the chain | ||
| firstInserted = -1 // Index of the first non-ignored header | ||
| newTD = new(big.Int).Set(ptd) // Total difficulty of inserted chain | ||
| inserted []rawdb.NumberHash // Ephemeral lookup of number/hash for the chain |

Why is this a slice and not a simple number if we only care about how many header we've inserted?
* all: work for eth1/2 transtition
* consensus/beacon, eth: change beacon difficulty to 0
* eth: updates
* all: add terminalBlockDifficulty config, fix rebasing issues
* eth: implemented merge interop spec
* internal/ethapi: update to v1.0.0.alpha.2
This commit updates the code to the new spec, moving payloadId into
it's own object. It also fixes an issue with finalizing an empty blockhash.
It also properly sets the basefee
* all: sync polishes, other fixes + refactors
* core, eth: correct semantics for LeavePoW, EnterPoS
* core: fixed rebasing artifacts
* core: light: performance improvements
* core: use keyed field (f)
* core: eth: fix compilation issues + tests
* eth/catalyst: dbetter error codes
* all: move Merger to consensus/, remove reliance on it in bc
* all: renamed EnterPoS and LeavePoW to ReachTDD and FinalizePoS
* core: make mergelogs a function
* core: use InsertChain instead of InsertBlock
* les: drop merger from lightchain object
* consensus: add merger
* core: recoverAncestors in catalyst mode
* core: fix nitpick
* all: removed merger from beacon, use TTD, nitpicks
* consensus: eth: add docstring, removed unnecessary code duplication
* consensus/beacon: better comment
* all: easy to fix nitpicks by karalabe
* consensus/beacon: verify known headers to be sure
* core: comments
* core: eth: don't drop peers who advertise blocks, nitpicks
* core: never add beacon blocks to the future queue
* core: fixed nitpicks
* consensus/beacon: simplify IsTTDReached check
* consensus/beacon: correct IsTTDReached check
