This replaces old style errors.Wrap with modern fmt.Errorf and removes
the (direct) dependency on github.com/pkg/errors. A couple of cases are
adjusted by hand as previously errors.Wrap(nil, ...) would return nil,
which is not what fmt.Errorf does.
Currently the `Run()` function of the CLI always uses `os.Args` directly.
This change adds an additional `RunWithArgs()` function that allows passing
arguments as `[]string` instead. This is useful when linking against
Syncthing as a library to be able to also expose the CLI.
Consistently use double dashes and fix typos -conf, -data-dir and
-verify.
Applies also to tests running the syncthing binary for consistency.
* Fix mismatched option name --conf in cli subcommand.
According to the source code comments, the cli option flags should
mirror those from the serve subcommand where applicable. That one is
actually called --config though.
* cli: Fix help text option placeholders.
The urfave/cli package uses the Value field of StringFlag to provide a
default value, not to name the placeholder. That is instead done with
backticks around some part of the Usage field.
* cli: Add missing --data flag in subcommand help text.
The urfave/cli based option parsing uses a fake flags collection to
generate help texts matching the used global options. But the --data
option was omitted from it, although it is definitely required when
using --config as well. Note that it cannot just be ignored, as some
debug stuff actually uses the DB:
syncthing cli --data=/bar --config=/foo debug index dump
* cmd/syncthing: Don't fail early on api setup error (fixes 7558)
* switch to factory pattern
* refactor config command to show help on nothing
* wip
* wip
* already abort in before
