This adds an option to direct log output to a file. This feature has been
requested a lot. It's sometimes useful to have this available when running
geth in an environment that doesn't easily allow redirecting the output.

Notably, there is no support for log rotation with this change. The --log.file option
opens the file once on startup and then keeps writing to the file handle. 
This can become an issue when external log rotation tools are involved, so it's
best not to use them with this option for now.

This PR fixes a subtle bug in t8n. After this PR, t8n behaves like our state-test runner in certain pre-EIP-158 scenarios

This PR replaces fastcache with a pretty simple LRU which does not require explicit closing.

When the interpreter is configured to use extra-eips, this change makes it so that all the opcodes are deep-copied, to prevent accidental modification of the 'base' jumptable.

PR #26082 added account listing to OnSignerStartup but did not consider the case where a user has a large number of accounts which would be annoying to display.

This PR updates showAccounts() so that if there are more than 20 accounts available the user sees the first 20 displayed in the console followed by: First 20 accounts listed (N more available).

This PR adds a 60 second timeout to graphql queries.

This adds new commands to turn a node key file into signed ENR / node ID.

Many of the other types have a function to convert the type to a big.Int,
but Address was missing this function.

It is useful to be able to turn an Address into a big.Int when doing
EVM-like computations natively in Go. Sometimes a Solidity address
type is casted to a uint256 and having a Big method on the Address
type makes this easy.

Instead of using a limit of three nodes per message, we can pack more nodes
into each message based on ENR size. In my testing, this halves the number
of sent NODES messages, because ENR size is usually < 300 bytes.

This also adds RLP helper functions that compute the encoded size of
[]byte and string.

Reports accounts known to Clef during startup, after master seed is provided by the user.

This PR now also includes a fix to the problem of mult-routines building blocks on the same input. This PR works as before with regards to stopping the work, but it just will not spin up a second routine if one is already building. So if the CL does N calls to FCU+buildblock, and N calls to GetPayload, only the first of each will do something, the other calls will be mostly no-ops.

This PR also adds printout of the payload id into the logs.

This PR changes geth to read the eip1559 params from the chain config instead of the globals.

This way the parameters may be changed by forking the chain config code, without creating a large diff throughout the past and future usages of the parameters.

Noticed that lookupDistances for FINDNODE requests didn't consider 256 a valid
distance. This is actually part of the example in the comment above the
function, surprised that wasn't tested before.

don't ignore errors returned by core.NewBlockChain when initializing tests

* miner, eth: implement recommit for payload building

* miner: address comments from marius

Removed parentheses in line 71 because line 80 doesn't have them either.

fix typo

* fixed bytes with size larger than 32 bytes is not allowed

* add testcase

Fixes #25943

In some cases, it is desirable to capture what is triggered by each trace, when using the `callTracer`. For example: call `USDT.transfer` will trigger a `Transfer(from, to, value)` event.

This PR adds the option to capture logs to the call tracer, by specifying `{"withLog": true}` in the tracerconfig. 
Any logs belonging to failed/reverted call-scopes are removed from the output, to prevent interpretation mistakes.

Inner call reverts will now return the reason similar to the top-level call. Separately, if top-level call is of type CREATE and it fails, its `to` field will now be cleared to `0x00...00` instead of being set to the created address.

This PR adds a parameter to startup, --synctarget. The synctarget flag is a developer-flag, that can be useful in some scenarios as a replacement for a CL node. It defines a fixed block sync target:

geth --syncmode=full --synctarget=./block_15816882.hex_rlp 

The --synctarget is only made available during syncmode=full
