This makes sure that `util.format` uses `String` to stringify an object
in case the object has an own property named `toString` with type
`function`. That way objects that do not have such function are still
inspected using `util.inspect` and the old behavior is preserved as
well.

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.

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.

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.

Provide public APIs for native typechecking that is actually useful.
The motivation for this is providing alternatives to userland
modules that would currently rely on `process.binding('util')`.

Since the default for depth is changed to `Infinity` it is logical
to change the %o default to the same as well.
Using %o with `util.format` will now always print the whole object.

The current default is not ideal in most use cases. Therefore it is
changed to showing unlimited depth in case util.inspect is called
directly. The default is kept as before for console.log and similar.
Using console.dir will now show a depth of up to five and
console.assert / console.trace will show a unlimited depth.

The current default formatting is not ideal and this improves
the situation by formatting the output more intuitiv.
1) All object keys are now indented by 2 characters instead of
sometimes 2 and sometimes 3 characters.
2) Each object key will now use an individual line instead of
sharing a line potentially with multiple object keys.
3) Long strings will now be split into multiple lines in case
they exceed the "lineBreak" option length (including the
current indentation).
4) Opening braces are now directly behind a object property
instead of using a new line.
5) Switch inspect "base" order. In case the compact option is set
to `false`, inspect will now print
"[Function: foo] {\n property: 'data'\n}"
instead of
"{ [Function: foo]\n property: 'data'\n}".

Currently the documentation states that promisify() will result in
undefined behavior if bad arguments are passed. This is not
necessarily the case, since the behavior is well defined, but just
not useful.

Change documentation-only deprecation for custom inspection using
`object.inspect` property to a runtime deprecation.
This is a breaking change. Custom inspection via `object.inspect` is
deprecated because there is a more robust Symbol-based alternative to
`.inspect` and the custom inspection via `object.inspect` feature means
that people can accidentally break `console.log()` simply by attaching a
`.inspect` property to their objects. Note that since this is a
deprecation, the custom inspection will still work. The breaking change
is simply the printing of a warning which could alarm users, break tests
or other things that might be dependent on specific output, etc.

If another function has already emitted the deprecation warning with the
same code as the warning that is about to be emitted, do not emit the
warning.
This is a breaking change. Previously, different functions could emit
the same deprecation warning multiple times. This was a known bug rather
than a feature, but this change is being treated as a breaking change
out of caution. Identical deprecation warnings should not be emitted.
