This is a manually edited and outdated list of builtin modules.
Instead, it is better to rely upon the officially documented way
to get a list of builtin modules.
As a side by fix this makes sure all exports are in one place. Thus,
it is easier to see what parts are actually exported and which are
not.

This improves the autocompletion for require calls. It had multiple
small issues so far. Most important: it won't suggest completions for
require statements that are fully written out. Second, it'll detect
require calls that have whitespace behind the opening bracket. Third,
it makes sure node modules are detected as such instead of only
suggesting them as folders. Last, it adds suggestions for input that
starts with backticks.

This replaces the internally used hard coded Node.js core module
list with the actual internal existent modules. That way all modules
are automatically picked up instead of having to update the list
manually.
This currently only applies to the REPL and to the Node.js `eval`
functionality (User passed `-e` or `--eval` arguments to Node without
`-i` or `--interactive`).

Custom eval functions might have a very different behavior than the

it was also only exported in case the instance was started with

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 fixes two issues in the REPL when it is started with a new context
(useGlobal option set to `false`):
- The `primordials` object does not contain all builtins, so the
filtering based on property names from `primordials` was wrong.
- The autocompleter did not take builtin names into account because
they are not properties of the context object.
A list of all global builtin names is created lazily when needed. It is
used for filtering for the copy and for adding those names to the
autocompleter list.
