* 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)

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 fixes a theoretical double lock condition which could occur in

    indexer.AddChildIndexer(indexer)

Nobody would ever do that though.

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.

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.

* all: seperate consensus error and evm internal error

There are actually two types of error will be returned when
a tranaction/message call is executed: (a) consensus error
(b) evm internal error. The former should be converted to
a consensus issue, e.g. The sender doesn't enough asset to
purchase the gas it specifies. The latter is allowed since
evm itself is a blackbox and internal error is allowed to happen.

This PR emphasizes the difference by introducing a executionResult
structure. The evm error is embedded inside. So if any error
returned, it indicates consensus issue happens.

And also this PR improve the `EstimateGas` API to return the concrete
revert reason if the transaction always fails

* accounts/abi: prevent recalculation of ID, Sig and String

* accounts/abi: fixed unpacking of no values

* accounts/abi: multiple fixes to arguments

* accounts/abi: refactored methodName and eventName

This commit moves the complicated logic of how we assign method names
and event names if they already exist into their own functions for
better readability.

* accounts/abi: prevent recalculation of internal

In this commit, I changed the way we calculate the string
representations, sig representations and the id's of methods. Before
that these fields would be recalculated everytime someone called .Sig()
.String() or .ID() on a method or an event.

Additionally this commit fixes issue #20856 as we assign names to inputs
with no name (input with name "" becomes "arg0")

This adds two new methods to UDPv5, AllNodes and LocalNode.

AllNodes returns all the nodes stored in the local table; this is
useful for the purposes of metrics collection and also debugging any
potential issues with other discovery v5 implementations.

LocalNode returns the local node object. The reason for exposing this
is so that users can modify and set/delete new key-value entries in
the local record.
