Prior to this change, f.begin (and possibly end) stay negative, leading to strange results later in the code. With this change, filters using "safe" and "finalized" block produce results consistent w/ the overall behavior of this RPC method.

This PR introduces a new mechanism in chain tracer for preventing creating too many trace states.
The workflow of chain tracer can be divided into several parts:
- state creator generates trace state in a thread
- state tracer retrieves the trace state and applies the tracing on top in another thread
- state collector gathers all result from state tracer and stream to users
It's basically a producer-consumer model here, while if we imagine that the state producer generates states too fast, then it will lead to accumulate lots of unused states in memory. Even worse, in path-based state scheme it will only keep the latest 128 states in memory, and the newly generated state will invalidate the oldest one by marking it as stale.
The solution for fixing it is to limit the speed of state generation. If there are over 128 states un-consumed in memory, then the creation will be paused until the states are be consumed properly.
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.

This PR makes it so that the snap server responds to trie heal requests when possible, even if the snapshot does not exist. The idea being that it might prolong the lifetime of a state root, so we don't have to pivot quite as often.
The call tracer and prestate tracer store data JSON-encoded in memory. In order to support alternative encodings (specifically RLP), it's better to keep data a native format during tracing. This PR does marshalling at the end, using gencodec.
OBS!
This PR changes the call tracer result slightly:
- Order of type and value fields are changed (should not matter).
- Output fields are completely omitted when they're empty (no more output: "0x"). Previously, this was only _sometimes_ omitted (e.g. when call ended in a non-revert error) and otherwise 0x when the output was actually empty.

Sometimes we get stuck on db compaction, and the CL re-issues the "same" command to us multiple times. Each request get stuck on the same place, in the middle of the handler.
This changes makes it so we do not reprocess the same payload, but instead detects it early.
This changes the CI / release builds to use the latest Go version. It also
upgrades golangci-lint to a newer version compatible with Go 1.19.
In Go 1.19, godoc has gained official support for links and lists. The
syntax for code blocks in doc comments has changed and now requires a
leading tab character. gofmt adapts comments to the new syntax
automatically, so there are a lot of comment re-formatting changes in this
PR. We need to apply the new format in order to pass the CI lint stage with
Go 1.19.
With the linter upgrade, I have decided to disable 'gosec' - it produces
too many false-positive warnings. The 'deadcode' and 'varcheck' linters
have also been removed because golangci-lint warns about them being
unmaintained. 'unused' provides similar coverage and we already have it
enabled, so we don't lose much with this change.
This PR simplifies the logic of chain tracer and also adds the unit tests.
The most important change has been made in this PR is the state management. Whenever a tracing state is acquired there is a corresponding release function be returned as well. It must be called once the state is used up, otherwise resource leaking can happen.
And also the logic of state management has been simplified a lot. Specifically, the state provider(eth backend, les backend) should ensure the state is available and referenced. State customers can use the state according to their own needs, or build other states based on the given state. But once the release function is called, there is no guarantee of the availability of the state.

announcement messages it sends are also smaller.

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.

This enables the following linters
- typecheck
- unused
- staticcheck
- bidichk
- durationcheck
- exportloopref
- gosec
WIth a few exceptions.
- We use a deprecated protobuf in trezor. I didn't want to mess with that, since I cannot meaningfully test any changes there.
- The deprecated TypeMux is used in a few places still, so the warning for it is silenced for now.
- Using string type in context.WithValue is apparently wrong, one should use a custom type, to prevent collisions between different places in the hierarchy of callers. That should be fixed at some point, but may require some attention.
- The warnings for using weak random generator are squashed, since we use a lot of random without need for cryptographic guarantees.
Previously on Geth startup we just logged the chain config is a semi-json-y format. Whilst that worked while we had a handful of hard-forks defined, currently it's kind of unwieldy.
This PR converts that original data dump and converts it into a user friendly - alas multiline - log output.
This PR adds support for block overrides when doing debug_traceCall.
- Previously, debug_traceCall against pending erroneously used a common.Hash{} stateroot when looking up the state, meaning that a totally empty state was used -- so it always failed,
- With this change, we reject executing debug_traceCall against pending.
- And we add ability to override all evm-visible header fields.
#23773 added a JS tracer which uses Goja as its engine. In this PR I remove the previous tracer which used duktape as well as remove the dependencies.
This PR also comes with 2 fixes in the Goja tracer and one small behavioural change:
I had handled errors in the native Go functions by panicing. My oversight was that Goja only handles panics with a Goja.Value as argument. The difference is panic(goja.Value) allows JS to catch the exception whereas Interrupt(error) doesn't.
There was a race in how I handled Stop.
Because of 1. some of the methods that simply return nil on error (like memory.slice) now throw an exception.
This adds a JS tracer runtime environment based on the Goja VM. The new
runtime replaces the duktape runtime, which will be removed soon.
Goja is implemented in Go and is faster for cases where the Go <-> JS
transition overhead dominates overall performance. It is faster because
duktape is written in C, and the transition cost includes the cost of using
cgo. Another reason for using Goja is that go-duktape is not maintained
anymore.
We expect the performace of JS tracing to be at least as good or better with
this change.
