Removes the new --log.logfmt directive and hides --log.json, replacing both with log.format=(json|logfmt|terminal). The hidden log.json option is still respected if log.format is not specified for backwards compatibility.

This adds an option to direct log output to a file. This feature has been
requested a lot. It's sometimes useful to have this available when running
geth in an environment that doesn't easily allow redirecting the output.
Notably, there is no support for log rotation with this change. The --log.file option
opens the file once on startup and then keeps writing to the file handle.
This can become an issue when external log rotation tools are involved, so it's
best not to use them with this option for now.
This change updates our urfave/cli dependency to the v2 branch of the library.
There are some Go API changes in cli v2:
- Flag values can now be accessed using the methods ctx.Bool,
ctx.Int, ctx.String, ... regardless of whether the flag is 'local' or
'global'.
- v2 has built-in support for flag categories. Our home-grown category
system is removed and the categories of flags are assigned as part of
the flag definition.
For users, there is only one observable difference with cli v2: flags must now
strictly appear before regular arguments. For example, the following command is
now invalid:
geth account import mykey.json --password file.txt
Instead, the command must be invoked as follows:
geth account import --password file.txt mykey.json
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.
* internal/debug: remove deprecated flags
The removed flags are removed in the main portion of geth, this removes it internally too.
* internal/debug: remove legacy --debug and legacy --backtrace flag
* Update flags.go

This change adds support for logging JSON records when the --log.json flag is
given. The --debug and --backtrace flags are deprecated and replaced by
--log.debug and --log.backtrace.
While changing this, it was noticed that the --memprofilerate and
--blockprofilerate were ineffective (they were always overridden even if
--pprof.memprofilerate was not set). This is also fixed.

Exposing /debug/metrics and /debug/metrics/prometheus was dependent
on --pprof, which also exposes other HTTP APIs. This change makes it possible
to run the metrics server on an independent endpoint without enabling pprof.
* rpc flags related to starting http server renamed to http
* old rpc flags aliased and still functional
* pprof flags fixed
* renames gpo related flags
* linted
* renamed rpc flags for consistency and clarity
* added warn logs
* added more warn logs for all deprecated flags for consistency
* moves legacy flags to separate file, hides older flags under show-deprecated-flags command
* legacy prefix and moved some more legacy flags to legacy file
* fixed circular import
* added docs
* fixed imports lint error
* added notes about when flags were deprecated
* cmd/utils: group flags by deprecation date + reorder by date,
* modified deprecated comments for consistency, added warn log for --rpc
* making sure deprecated flags are still functional
* show-deprecated-flags command cleaned up
* fixed lint errors
* corrected merge conflict
* IsSet --> GlobalIsSet
* uncategorized flags, if not deprecated, displayed under misc

* log: delete RotatingFileHandler
We added this for the dashboard, which is gone now. The
handler never really worked well and had data race and file
handling issues.
* internal/debug: remove unused RotatingFileHandler setup code
The debug package provides an RPC wrapper for glog settings and the
debugging facilities of the Go runtime. They can be triggered through
both command line flags and the IPC listener.
