This fixes a problem in the SizeConstrainedLRU. The SCLRU uses an underlying simple lru which is not thread safe.
During the Get operation, the recentness of the accessed item is updated, so it is not a pure read-operation. Therefore, the mutex we need is a full mutex, not RLock.
This PR changes the mutex to be a regular Mutex, instead of RWMutex, so a reviewer can at a glance see that all affected locations are fixed.
This changes how we read performance metrics from the Go runtime. Instead
of using runtime.ReadMemStats, we now rely on the API provided by package
runtime/metrics.
runtime/metrics provides more accurate information. For example, the new
interface has better reporting of memory use. In my testing, the reported
value of held memory more accurately reflects the usage reported by the OS.
The semantics of metrics system/memory/allocs and system/memory/frees have
changed to report amounts in bytes. ReadMemStats only reported the count of
allocations in number-of-objects. This is imprecise: 'tiny objects' are not
counted because the runtime allocates them in batches; and certain
improvements in allocation behavior, such as struct size optimizations,
will be less visible when the number of allocs doesn't change.
Changing allocation reports to be in bytes makes it appear in graphs that
lots more is being allocated. I don't think that's a problem because this
metric is primarily interesting for geth developers.
The metric system/memory/pauses has been changed to report statistical
values from the histogram provided by the runtime. Its name in influxdb has
changed from geth.system/memory/pauses.meter to
geth.system/memory/pauses.histogram.
We also have a new histogram metric, system/cpu/schedlatency, reporting the
Go scheduler latency.
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.
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).

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.

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.
