Introduces the first built-in live tracer. The supply tracer tracks ETH supply changes across blocks
and writes the output to disk. This will need to be enabled through CLI using the `--vmtrace supply` flag.

This fixes an issue for `debug_traceBlock*` methods where the BASEFEE opcode was returning always 0. This caused the method return invalid results.

The beacon root when applied in `state_processor.go` is performed right before executing transaction. That means that contract reliying on this value would query the same value found in the block header.
In that spirit, it means that any tracing/operation relying on state data which touches transaction must have updated the beacon root before any transaction processing.
Adds a flag `--trace.callframes` to t8n which will log info when entering or exiting a call frame in addition to the execution steps.

Here we add a Go API for running tracing plugins within the main block import process.
As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.
The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of
requiring an interface, for several reasons:
- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
to implement only the hooks you want to actually use.
All existing tracers in eth/tracers/native have been rewritten to use the new hook system.
This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

The prestateTracer was reporting an inaccurate nonce for the contract being created in
post EIP-158 transactions. Correct nonce is 0, due to the issue nonce was being reported as 1.
eth_call and debug_traceCall allow users to override various block fields, among them base fee. However the overriden base fee was not considered for computing the effective gas price of that message, and instead base fee of the base block was used. This has been fixed in this commit.
This change makes use of uin256 to represent balance in state. It touches primarily upon statedb, stateobject and state processing, trying to avoid changes in transaction pools, core types, rpc and tracers.
This change simplifies the logic for indexing transactions and enhances the UX when transaction is not found by returning more information to users.
Transaction indexing is now considered as a part of the initial sync, and `eth.syncing` will thus be `true` if transaction indexing is not yet finished. API consumers can use the syncing status to determine if the node is ready to serve users.
In the tracing tests, the base fee was generally set to nil. This commit changes this to pass the proper base instead, and fixes the few tests which become broken by the change.
This change fixes two type-inconsistencies in the JS tracer:
- In most places we return byte arrays as a `Uint8Array` to the tracer. However it seems we missed doing the conversion for `ctx` fields which are passed to the tracer during `result`. They are passed as simple arrays. I think Uint8Arrays are more suitable and we should change this inconsistency. Note: this will be a breaking-change. But I believe the effect is small. If we look at our tracers we see that these fields (`ctx.from`, `ctx.to`, etc.) are used in 2 ways. Passed to `toHex` which takes both array or buffer. Or the length was measured which is the same for both types.
- The `slice` taking in `int, int` params versus `memory.slice` taking `int64, int64` params. I suggest changing `slice` types to `int64`. This should have no effect almost in any case.
Currently, one can use the "withLogs" parameter to include logs in the
callTracer results, which allows the user to see at which trace level
was each log emitted.
This commit adds a position field to the logs which determine
the exact ordering of a call's logs and its subcalls. This would
be useful e.g. for explorers wishing to display the flow of execution.

The Go authors updated golang/x/ext to change the function signature of the slices sort method.
It's an entire shitshow now because x/ext is not tagged, so everyone's codebase just
picked a new version that some other dep depends on, causing our code to fail building.
This PR updates the dep on our code too and does all the refactorings to follow upstream...
The struct logger (or opcode tracer) was missing the return data field even
if this was explicitly enabled by user via `"enableReturnData": true` in the config.
This PR fixes this issue.

We had to do this workaround because it wasn't possible to export typed arrays from
JS to []byte. This was added in dop251/goja@2352993, so we can use the better way now.
This PR modifies the interface for the results of `debug_traceBlock` and `debug_traceCall` by adding the `txHash`, allowing users to identify which transaction's trace result corresponds to.

Adds an optional config parameter to eth_call which allows users to override block context fields (same functionality that was added to traceCall in #24871)
