core/state/snapshot: release iterator after verification

tests: cleanup snapshot generator goroutine leak

* accounts/abi: removed Kind from Type struct

* accounts/abi: removed unused code

This fixes an issue with clef, which already transforms the signature
to use the legacy 27/28 encoding.

Fixes #20994

core/state/snapshot: fix journal nil deserialziation

* core/state/snapshot: implement storage iterator

* core/state/snapshot, tests: implement helper function

* core/state/snapshot: fix storage issue

If an account is deleted in the tx_1 but recreated in the tx_2,
the it can happen that in this diff layer, both destructedSet
and storageData records this account. In this case, the storage
iterator should be able to iterate the slots belong to new account
but disable further iteration in deeper layers(belong to old account)

* core/state/snapshot: address peter and martin's comment

* core/state: address comments

* core/state/snapshot: fix test

* signer: properly handle terminal escape characters

* log: use strconv conversion instead of custom escape function

* log: remove relection tests for nil

golang-lru is now a go module, and the upgrade corrects a couple
of minor issues. In particular, the library could crash if you inserted
nil into an LRU cache.

This is a resubmit of #20668 which rewrites the problematic test
without any additional goroutines. It also documents the test better.

The purpose of this test is checking whether log events are sent
correctly when importing blocks. The test was written at a time when
blockchain events were delivered asynchronously, making the check hard
to pull off. Now that core.BlockChain delivers events synchronously
during the call to InsertChain, the test can be simplified.

This corrects the call to eth_getBlockByNumber, which previously
returned this error:

  can't get latest block: missing value for required argument 1

This fixes a theoretical double lock condition which could occur in

    indexer.AddChildIndexer(indexer)

Nobody would ever do that though.

* accounts/abi: removed unnused arguments.LengthNonIndexed

Due to refactors to the code, we do not need the arguments.LengthNonIndexed function anymore.
You can still get the length by calling len(arguments.NonIndexed())

Rather than just closing the underlying network listener to stop our
HTTP servers, use the graceful shutdown procedure, waiting for any
in-process requests to finish.

eth: fix shutdown regression to abort downloads, not just cancel

It is possible to specify enode URLs using domain name since
commit b90cdbaa, but the code comment still said that only
IP addresses are allowed.
