This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21. Main changes are as follows: * removes any log handlers that were unused in the Geth codebase. * Json, logfmt, and terminal formatters are now slog handlers. * Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options. * `--log.backtraceat` and `--log.debug` are removed. The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged. A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed. ---- For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did ```golang log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true)))) ``` You now instead need to do ```golang log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true))) ``` See more about reasoning here: https://github.com/ethereum/go-ethereum/issues/28558#issuecomment-1820606613
