eth/tracers: add position field for callTracer logs (#28389)
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.

eth/tracers: fix flatCallTracer crasher (#27304)
FlatCallTracer had a crasher when it was passed `onlyTopCall: true` as config.
This PR ignores config fields inherited from the normal call tracer.

eth/tracers: report correct gasLimit in call tracers (#27029)
This includes a semantic change to the `callTracer` as well as `flatCallTracer`.
The value of field `gas` in the **first** call frame will change as follows:

- It previously contained gas available after initial deductions (i.e. tx costs)
- It will now contain the full tx gasLimit value

eth/tracers: add native flatCallTracer (aka parity style tracer) (#26377)
Adds support for a native call tracer with the Parity format, which outputs call frames
in a flat array. This tracer accepts the following options:

- `convertParityErrors: true` will convert error messages to match those of Parity
- `includePrecompiles: true` will report all calls to precompiles. The default
  matches Parity's behavior where CALL and STATICCALLs to precompiles are excluded

Incompatibilities with Parity include:

- Parity removes the result object in case of failure. This behavior is maintained
  with the exception of reverts. Revert output usually contains useful information,
  i.e. Solidity revert reason.
- The `gasUsed` field accounts for intrinsic gas (e.g. 21000 for simple transfers)
  and refunds unlike Parity
- Block rewards are not reported

core/vm: set tracer-observable value of a delegatecall to match parent value (#26632)
This is a breaking change in the tracing hooks API as well as semantics of the callTracer:

- CaptureEnter hook provided a nil value argument in case of DELEGATECALL. However to stay consistent with how delegate calls behave in EVM this hook is changed to pass in the value of the parent call.
- callTracer will return parent call's value for DELEGATECALL frames.

eth/tracers: add withLog to callTracer (#25991)
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.

Fix trace call for inner reverts (#25971)
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.

eth/tracers: add diffMode to prestateTracer (#25422)
Backwards compatibility warning: The result will from now on omit empty fields instead
of including a zero value (e.g. no more `balance: '0x'`).

The prestateTracer will now take an option `diffMode: bool`. In this mode
the tracer will output the pre state and post data for the modified parts of state.
Read-only accesses will be completely omitted. Creations (be it account or slot)
will be signified by omission in the `pre` list and inclusion in `post`. Whereas
deletion (be it account or slot) will be signified by inclusion in `pre` and omission
in `post` list.

eth/tracers: add onlyTopCall option to callTracer (#25430)
This PR allows users to pass in a config object directly to the tracers. Previously only the struct logger was configurable.

It also adds an option to the call tracer which if enabled makes it ignore any subcall and collect only information about the top-level call. See #25419 for discussion.

The tracers will silently ignore if they are passed a config they don't care about.
