Adds a `repl.setupHistory()` instance method so that
programmatic REPLs can also write history to a file.
This change also refactors all of the history file
management to `lib/internal/repl/history.js`, cleaning
up and simplifying `lib/internal/repl.js`.

and that callback throws an error, it will be swallowed by the nested

without any indication of an error (including a status code).

This reverts commit b994b8eff6.
This caused regressions in ecosystem code. While the change originally
was semver-major and could be postponed until after Node.js 10,
I think reverting it is a good choice at this point.
Also, I personally do not think defaulting to a shallow inspect
is a bad thing at all – quite the opposite: It makes `util.inspect()`
give an overview of an object, rather than providing a full
display of its contents. Changing the `depth` default to infinity
fundamentally changed the role that `util.inspect()` plays,
and makes output much more verbose and thus at times unusable
for `console.log()`-style debugging.
