## Why this should be merged
Required for
[ACP-194](https://github.com/avalanche-foundation/ACPs/tree/main/ACPs/194-streaming-asynchronous-execution#gas-charged)
$\lambda$ bound on gas consumption.
## How this works
Hook into `core.StateTransition.TransitionDb()` as this is the bottom of
all execution paths (e.g. `core.ApplyTransaction()` as used in SAE,
`core.StateProcessor.Process(*Block,...)`, etc.). Once consumed gas is
no longer changing (i.e. after all spends and refunds), the transaction
limit is passed to the hook to determine the minimum consumption, which
is applied.
## How this was tested
Unit test via `core.ApplyTransaction()` as this is our entry point in
SAE.

## Why this should be merged
Adds logging of `libevm` modification of default behaviour.
## How this works
1. Introduces `log.Lazy` functions to allow expensive logging operations
to be computed i.f.f. required by the logging level.
2. Adds `Info` logging for registration of types and `Debug` logging for
all else.
3. Only paths that change behaviour in a potentially unpredictable
manner are logged; of note, RLP / JSON encoding is _not_ considered
unpredictable given that registered extras are logged.
4. The minimal viable package, `set`, was necessary because we don't
want to depend on `avalanchego` and the `hashicorp/go-set` latest
version requires a later version of Go. #153 tracks a swap to the latter
when possible.
The `eth/tracers/internal/tracetest` test flaked at least twice
(unrelated to these changes) so I've marked it as such since it's not
worth a separate PR.
## How this was tested
New unit test on `log.Lazy` + `set` methods. Existing CI for the rest as
it's a refactor.
## Why this should be merged
Cleans up loose ends after renaming the Go module. Also adds an
introduction to the README to explain the purpose of libevm.
## How this works
The changed hash in the workflow is just a fix (although a no-op). The
spaces after the copyright headers are to stop them from [showing up in
documentation](https://pkg.go.dev/github.com/ava-labs/libevm@v1.13.14-0.1.0-rc.1/params).
## How this was tested
n/a
* feat: pseudo-generic extra payloads in `params.ChainConfig` and `params.Rules`
* feat: `params.ExtraPayloadGetter` for end-user type safety
* refactor: payloads only available through `params.ExtraPayloadGetter`
* chore: make `libevm/examples/extraparams` a `params` testable example
* doc: `libevm/pseudo` package comments and improved readability
* doc: `params.*Extra*` comments and improved readability
* doc: `params.ExtraPayloadGetter` comments and improved readability
* doc: `params/config.libevm_test.go` comments and improved readability
* refactor: simplify `params.ChainConfig.UnmarshalJSON()`
* refactor: abstract new/nil-pointer creation into `pseudo.Constructor`s
* feat: precompile override via `params.Extras` hooks
* doc: flesh out `PrecompileOverride()` in example
* doc: complete commentary and improve readability
* refactor: `ChainConfig.Hooks()` + `Rules` equivalent
* chore: rename precompiles test file in keeping with geth equivalent
* feat: stateful precompiles + allowlist hooks
The allowlist hooks are included in this commit because they allow for the same functionality as stateful precompiles in `ava-labs/coreth` and `ava-labs/subnet-evm`.
* fix: `StateTransition.canExecuteTransaction()` used `msg.From` instead of `To`
* test: `params.RulesHooks.CanCreateContract` integration
* test: `params.RulesHooks.CanExecuteTransaction` integration
* test: `vm.NewStatefulPrecompile()` integration
* refactor: simplify test of `CanCreateContract`
* refactor: abstract generation of random `Address`/`Hash` values
* doc: full documentation + readability refactoring/renaming
* fix: remove circular dependency in tests
