* Rename `newKvt()` -> `ctx.getKvt()`
why:
Clean up legacy shortcut. Also, the `KVT` returned is not instantiated
but refers to the shared `KVT` that resides in a context which is a
generalisation of an in-memory database fork. The function `ctx`
retrieves the default context.
* Rename `newTransaction()` -> `ctx.newTransaction()`
why:
Clean up legacy shortcut. The transaction is applied to a context as a
generalisation of an in-memory database fork. The function `ctx`
retrieves the default context.
* Rename `getColumn(CtGeneric)` -> `getGeneric()`
why:
No more a list of well known sub-tries needed, a single one is enough.
In fact, `getColumn()` did only support a single sub-tree by now.
* Reduce TODO list
* Use simpler schema when writing transactions, receipts, and withdrawals
Using MPT not only slow but also take up more spaces than needed.
Aristo will remove older tries and only keep the last block tries.
Using simpler schema will avoid those problems.
* Rename getTransaction to getTransactionByIndex
* Simplify txpool baseFeeGet
- Avoid using toEVMFork because we are not in EVM
- Rename `isLondon` to `isLondonOrLater`
* Remove timestamp from isLondonOrLater
It is common for many accounts to share the same code - at the database
level, code is stored by hash meaning only one copy exists per unique
program but when loaded in memory, a copy is made for each account.
Further, every time we execute the code, it must be scanned for invalid
jump destinations which slows down EVM exeuction.
Finally, the extcodesize call causes code to be loaded even if only the
size is needed.
This PR improves on all these points by introducing a shared
CodeBytesRef type whose code section is immutable and that can be shared
between accounts. Further, a dedicated `len` API call is added so that
the EXTCODESIZE opcode can operate without polluting the GC and code
cache, for cases where only the size is requested - rocksdb will in this
case cache the code itself in the row cache meaning that lookup of the
code itself remains fast when length is asked for first.
With 16k code entries, there's a 90% hit rate which goes up to 99%
during the 2.3M attack - the cache significantly lowers memory
consumption and execution time not only during this event but across the
board.
* Remove AccountStateDB
AccountStateDB should no longer be used.
It's usage have been reduce to read only operations.
Replace it with LedgerRef to reduce maintenance burden.
* remove extra spaces

This PR consolidates the split header-body sequences into a single EthBlock
sequence and cleans up the fallout from that which significantly reduces
block processing overhead during import thanks to less garbage collection
and fewer copies of things all around.
Notably, since the number of headers must always match the number of bodies,
we also get rid of a pointless degree of freedom that in the future could
introduce unnecessary bugs.
* only read header and body from era file
* avoid several unnecessary copies along the block processing way
* simplify signatures, cleaning up unused arguemnts and returns
* use `stew/assign2` in a few strategic places where the generated
nim assignent is slow and add a few `move` to work around poor
analysis in nim 1.6 (will need to be revisited for 2.0)

* Cleanup unneeded stateless and block witness code. Keeping MultiKeys which is used in the eth_getProofsByBlockNumber RPC endpoint which is needed for the Fluffy state network bridge.
* Rename generateWitness flag to collectWitnessData to better describe what the flag does. We only collect the keys of the touched accounts and storage slots but no block witness generation is supported for now.
* Move remaining stateless code into nimbus directory.
* Add vmstate parameter to ChainRef to fix test.
* Exclude *.in from check copyright year

* Workaround for 0 gas price estimation
The transaction spammer from Kurtosis estimates the gas price of its
transactions using 'eth_gasPrice'. Our implementation returns 0 when
no transactions have been executed yet, not taking into account the
EIP-1559 block base fee. Force a hardcoded minimum for now to unstuck.
* Adjust tests to cover new minimum gas fee
* Skip gas price test
* Introduce wrapper type for EIP-4844 transactions
EIP-4844 blob sidecars are a concept that only exists in the mempool.
After inclusion of a transaction into an execution block, only the
versioned hash within the transaction remains. To improve type safety,
replace the `Transaction.networkPayload` member with a wrapper type
`PooledTransaction` that is used in contexts where blob sidecars exist.

The transaction spammer from Kurtosis requests the nonce value of its
account based on 'pending' tag. As we lack that implementation, go with
the next best answer from the 'latest' tag. This does not include info
about transactions from the mempool that have not yet been executed.

Both types are not safe and require validation/conversion
