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.

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}".

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.
