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
* http2
* Added a `'ping'` event to `Http2Session` that is emitted whenever a
non-ack `PING` is received.
https://github.com/nodejs/node/pull/23009
* Added support for the `ORIGIN` frame.
https://github.com/nodejs/node/pull/22956
* Updated nghttp2 to 1.34.0. This adds RFC 8441 extended connect
protocol support to allow use of WebSockets over HTTP/2.
https://github.com/nodejs/node/pull/23284
* module
* Added `module.createRequireFromPath(filename)`. This new method can
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
`resolve` and `reject` functions are both called in a `Promise`
executor. https://github.com/nodejs/node/pull/22218
* url
* Added `url.fileURLToPath(url)` and `url.pathToFileURL(path)`. These
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
symbol registry as `Symbol.for('nodejs.util.inspect.custom')`.
https://github.com/nodejs/node/pull/20857
* Added support for `BigInt` numbers in `util.format()`.
https://github.com/nodejs/node/pull/22097
* V8 API
* A number of V8 C++ APIs have been marked as deprecated since they
have been removed in the upstream repository. Replacement APIs
are added where necessary. https://github.com/nodejs/node/pull/23159
* Windows
* The Windows msi installer now provides an option to automatically
install the tools required to build native modules.
https://github.com/nodejs/node/pull/22645
* Workers
* Debugging support for Workers using the DevTools protocol has been
implemented. https://github.com/nodejs/node/pull/21364
* The public `inspector` module is now enabled in Workers.
https://github.com/nodejs/node/pull/22769
* Added new collaborators:
* digitalinfinity - Hitesh Kanwathirtha

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.
