Using `util.inspect` on errors is going to highlight userland and
node_module stack frames from now on. This is done by marking Node.js
core frames grey and frames that contain `node_modules` in their path
yellow.
That way it's easy to grasp what frames belong to what code.

This changes the `compact` default from `true` to `3`. That mode
changes arrays to be grouped together, it alignes multiple small
entries on a single line in similar to `compact` true but only for
the most inner three depth levels and the closing brackets are
always on the same indentation as the openeing of the object instead
of at the same line as another property.
Big strings will be naturally broken into multiple lines instead of
having one huge line that is not well readable.
The output size mainly stays the same that way while it will be
smaller in case of big arrays.
Increasing the `breakLength` to 80 adjusts for most terminals that
support at least 80 characters in a single line and improves the
general output that way. A lot of calculations use the `breakLength`
to determine the concrete behavior.

This improves `util.format()` by returning more meaningful results
when using `%s` as specifier and any object as value. Besides that
`BigInt` will also be represented with an `n` at the end to indicate
that it's of type `BigInt`.

This overloads the `compact` option from `util.inspect()`. If it's
set to a number, it is going to align all most inner entries on the
same lign if they adhere to the following:
* The entries do not exceed the `breakLength` options value.
* The entry is one of the local most inner levels up the the one
provided in `compact`.

This prevents leaking of the internal `inspect()` properties when
using a custom inspect function.
It also aligns the indentation to the way it was in v8.0.0 since
that changed unintentionally. All strings returned by the custom
inspect function will now be indented appropriately to the current
depth.

Currently it is not possible to inspect getters. To prevent any side
effects this should not become a default but under lots of
circumstances it would still be useful to inspect getters. This way
it is possible to actively opt into inspecting those.

The `console` functions rely on the `util.format()` behavior. It
did not follow the whatwg spec when it comes to symbols in combination
with the %d, %i and %f format specifiers. Using a symbol argument in
combination with one of these specifiers resulted in an error instead
of returning `'NaN'`. This is now fixed by this patch.

This reverts commit ac7450a09a.
This fully reverts the changes to util.inspect depth.
It has caused breakage in logging to existing apps, and even
something as simple as `console.log(require)` will cause >1m freezes.
I've heard nothing but negative feedback (seriously not a single
person has expressed anything positive about this change) and
personally i find this change extremely annoying.

Two changes here which bring us closer to the console standard:
- Arguments to `util.format` are no longer formatted differently
depending on their order, with format strings being an exception.
- Format specifier formatting is now only triggered if the string
actually contains a format string.
Under the hood, we now use a single shared function to format the given
arguments which will make the code easier to read and modify.

Notable changes:
* assert
* The diff output is now a tiny bit improved by sorting object
properties when inspecting the values that are compared with each
other. https://github.com/nodejs/node/pull/22788
* cli
* The options parser now normalizes `_` to `-` in all multi-word
command-line flags, e.g. `--no_warnings` has the same effect as
`--no-warnings`. https://github.com/nodejs/node/pull/23020
* Added bash completion for the `node` binary. To generate a bash
completion script, run `node --completion-bash`. The output can be
saved to a file which can be sourced to enable completion.
https://github.com/nodejs/node/pull/20713
* crypto
* Added support for PEM-level encryption.
https://github.com/nodejs/node/pull/23151
* Added an API asymmetric key pair generation. The new methods
`crypto.generateKeyPair` and `crypto.generateKeyPairSync` can be
used to generate public and private key pairs. The API supports
RSA, DSA and EC and a variety of key encodings (both PEM and DER).
https://github.com/nodejs/node/pull/22660
* fs
* Added a `recursive` option to `fs.mkdir` and `fs.mkdirSync`. If
this option is set to true, non-existing parent folders will be
automatically created. https://github.com/nodejs/node/pull/21875

be used to create a custom require function that will resolve
modules relative to the filename path.
https://github.com/nodejs/node/pull/19360
* process
* Added a `'multipleResolves'` process event that is emitted whenever
a `Promise` is attempted to be resolved multiple times, e.g. if the

methods can be used to correctly convert between file: URLs and
absolute paths. https://github.com/nodejs/node/pull/22506
* util
* Added the `sorted` option to `util.inspect()`. If set to `true`,
all properties of an object and Set and Map entries will be sorted
in the returned string. If set to a function, it is used as a
compare function. https://github.com/nodejs/node/pull/22788
* The `util.instpect.custom` symbol is now defined in the global

The maximum hard limit that `util.inspect()` could theoretically handle
is the maximum string size. That is ~2 ** 28 on 32 bit systems and
~2 ** 30 on 64 bit systems.
Due to the recursive algorithm a complex object could easily exceed
that limit without throwing an error right away and therefore
crashing the application by exceeding the heap limit.
`util.inspect()` is fast enough to compute 128 MB of data below one
second on an Intel(R) Core(TM) i7-5600U CPU. This hard limit allows
to inspect arbitrary big objects from now on without crashing the
application or blocking the event loop significantly.
