Move the log calls in `internal` onto `logging`, and add what the process-wide logger setup and its tests need: `SetTextFormat` with a line filter for secret masking (replacing `report.MaskingFormatter`), `SetReportCaller`, `SetDefault` and `logtest.SetDefault`. After this only the `logging` package imports logrus.

`log.job.dir` makes the runner write a copy of every task's log to that directory, as `<start time>-task-<id>.log`: the rows exactly as Gitea received them, with the same masking and the job's result on the last line. Off by default, and what Gitea shows does not change.
`log.job.retention` (default `168h`) and `log.job.max_size` (default `1GB`) bound the directory. Documented in the README.
