Breaking changes:
- The ChainConfig was exposed to tracers via VMContext passed in
`OnTxStart`. This is unnecessary specially looking through the lens of
live tracers as chain config remains the same throughout the lifetime of
the program. It was there so that native API-invoked tracers could
access it. So instead we moved it to the constructor of API tracers.
Non-breaking:
- Change the default config of the tracers to be `{}` instead of nil.
This way an extra nil check can be avoided.
Refactoring:
- Rename `supply` struct to `supplyTracer`.
- Un-export some hook definitions.

When using the prestateTracer, in some cases users are only concerned
with balances or nonce information, and are not interested in the lengthy
contract code or storage data.
Therefore, this PR introduces two new configuration options in the
`prestateTracerConfig` structure:
- `disableCode`
- `disableStorage`
These options allow users to control whether the tracer returns contract
code and storage data during execution tracing. By setting these
options, users can more flexibly customize their needs and focus on
obtaining information that is more critical and relevant to their
specific use cases.
These options work with the default mode as well as `diffMode: true`.

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.

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.

FlatCallTracer had a crasher when it was passed `onlyTopCall: true` as config.
This PR ignores config fields inherited from the normal call tracer.

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

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

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.

This makes non-JS tracers execute all block txs on a single goroutine.
In the previous implementation, we used to prepare every tx pre-state
on one goroutine, and then run the transactions again with tracing enabled.
Native tracers are usually faster, so it is faster overall to use their output as
the pre-state for tracing the next transaction.

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.

In some cases, inner contract creation may not be successful, and an inner contract was not created. This PR fixes a crash that could occur when doing tracing in such situations.

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.
