Add a reverse search that works similar to the ZSH one. It is
triggered with <ctrl> + r and <ctrl> + s. It skips duplicated history
entries and works with multiline statements. Matching entries indicate
the search parameter with an underscore and cancelling with <ctrl> + c
or escape brings back the original line.
Multiple matches in a single history entry work as well and are
matched in the order of the current search direction. The cursor is
positioned at the current match position of the history entry.
Changing the direction immediately checks for the next entry in the
expected direction from the current position on.
Entries are accepted as soon any button is pressed that doesn't
correspond with the reverse search.
The behavior is deactivated for simple terminals. They do not support
most ANSI escape codes that are necessary for this feature.

This addresses an issue that is caused by lines that exceed the
current window columns. That would cause the preview to confuse the
REPL. This is meant as hot fix. The preview should be able to handle
these cases appropriately as well later on.

This improves the already existing preview functionality by also
checking for the input completion. In case there's only a single
completion, it will automatically be visible to the user in grey.
If colors are deactivated, it will be visible as comment.
This also changes some keys by automatically accepting the preview
by moving the cursor behind the current input end.

This adds input previews by using the inspectors eager evaluation
functionality.
It is implemented as additional line that is not counted towards
the actual input. In case no colors are supported, it will be visible
as comment. Otherwise it's grey.
It will be triggered on any line change. It is heavily tested against
edge cases and adheres to "dumb" terminals (previews are deactived
in that case).

So far it was not possible to modify the inspection defaults used by
the REPL from the running instance itself. This introduces a new
property on `util.inspect` which is only used inside the REPL and which
allows to modify the used inspection defaults at any point of time.

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`.

acorn and acorn-walk are now published as two different packages. Put
them both in subdirectories of `deps/acorn`.
Adapt the REPL's recoverable error detection to use the new API for
extending acorn parsers.
