This changes fixes a bug in the fetcher, where the timeout for how long to remember underpriced transaction was erroneously compared, and the timeout never hit.

* eth: enforce announcement metadatas and drop peers violating the protocol
* eth/fetcher: relax eth/68 validation a bit for flakey clients
* tests/fuzzers/txfetcher: pull in suggestion from Marius
* eth/fetcher: add tests for peer dropping
* eth/fetcher: linter linter linter linter linter
This PR will allow a previously underpriced transaction back in after a timeout
of 5 minutes. This will block most transaction spam but allow for transactions to
be re-broadcasted on networks with less transaction flow.

This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way
of keeping the blob sidecar within types.Transaction. It's better this way because most
code in go-ethereum does not care about blob transactions, and probably never will. This
will start mattering especially on the client side of RPC, where all APIs are based on
types.Transaction. Users need to be able to use the same signing flows they already
have.
However, since blobs are only allowed in some places but not others, we will now need to
add checks to avoid creating invalid blocks. I'm still trying to figure out the best place
to do some of these. The way I have it currently is as follows:
- In block validation (import), txs are verified not to have a blob sidecar.
- In miner, we strip off the sidecar when committing the transaction into the block.
- In TxPool validation, txs must have a sidecar to be added into the blobpool.
- Note there is a special case here: when transactions are re-added because of a chain
reorg, we cannot use the transactions gathered from the old chain blocks as-is,
because they will be missing their blobs. This was previously handled by storing the
blobs into the 'blobpool limbo'. The code has now changed to store the full
transaction in the limbo instead, but it might be confusing for code readers why we're
not simply adding the types.Transaction we already have.
Code changes summary:
- txpool.Transaction removed and all uses replaced by types.Transaction again
- blobpool now stores types.Transaction instead of defining its own blobTx format for storage
- the blobpool limbo now stores types.Transaction instead of storing only the blobs
- checks to validate the presence/absence of the blob sidecar added in certain critical places
* all: move main transaction pool into a subpool
* go.mod: remove superfluous updates
* core/txpool: review fixes, handle txs rejected by all subpools
* core/txpool: typos
The EmptyRootHash and EmptyCodeHash are defined everywhere in the codebase, this PR replaces all of them with unified one defined in core/types package, and also defines constants for TxRoot, WithdrawalsRoot and UncleRoot
* common, core, eth, les, trie: make prque generic
* les/vflux/server: fixed issues in priorityPool
* common, core, eth, les, trie: make priority also generic in prque
* les/flowcontrol: add test case for priority accumulator overflow
* les/flowcontrol: avoid priority value overflow
* common/prque: use int priority in some tests
No need to convert to int64 when we can just change the type used by the
queue.
* common/prque: remove comment about int64 range

* eth/fetcher: introduce some lag in tx fetching
* eth/fetcher: change conditions a bit
* eth/fetcher: use per-batch quota check

* cmd/devp2p/internal/ethtest: fix ignorign tx announcements from prev. tests
* cmd/devp2p/internal/ethtest: fix TestLargeTxRequest
This increases the number of tx relay messages the test waits for. Since
go-ethereum now processes incoming txs in smaller batches, the
announcement messages it sends are also smaller.

Some tests take quite some time during exit, which I think causes
some appveyor fails like this:
https://ci.appveyor.com/project/ethereum/go-ethereum/builds/39511210/job/xhom84eg2e4uulq3
One of the things that seem to take time during exit is waiting
(up to 100ms) for the syncbloom to close. This PR changes it to use
a channel, instead of looping with a 100ms wait.
This also includes some unrelated changes improving the reliability of
eth/fetcher tests, which fail a lot because they are time-dependent.
* accounts/abi/bind: fix bounded contracts and sim backend for 1559
* accounts/abi/bind, ethclient: don't rely on chain config for gas prices
* all: enable London for all internal tests
* les: get receipt type info in les tests
* les: fix weird test

The PR makes use of the stacktrie, which is is more lenient on resource consumption, than the regular trie, in cases where we only need it for DeriveSha

This PR adds some hardening in the lower levels of the protocol stack, to bail early on invalid data. Primarily, attacks that this PR protects against are on the "annoyance"-level, which would otherwise write a couple of megabytes of data into the log output, which is a bit resource intensive.
