2) Improve the performance of showing (Set|Map)Iterator by using
the cloned iterator instead of copying all entries first.
3) So far the output was strictly limited to up to 100 entries.
The limit will now depend on `maxArrayLength` instead (that

more entries exist than visible.

- Moves the creation of `process.binding()`, `process._linkedBinding()`
`internalBinding()` and `NativeModule` into a separate file
`lib/internal/bootstrap_loaders.js`, and documents them there.
This file will be compiled and run before `bootstrap_node.js`, which
means we now bootstrap the internal module & binding system before
actually bootstrapping Node.js.
- Rename the special ID that can be used to require `NativeModule`
as `internal/bootstrap_loaders` since it is setup there. Also put
`internalBinding` in the object exported by `NativeModule.require`
instead of putting it inside the `NativeModule.wrapper`
- Use the original `getBinding()` to get the source code of native
modules instead of getting it from `process.binding('native')`
so that users cannot fake native modules by modifying the binding
object.
- Names the bootstrapping functions so their names show up
in the stack trace.

This commit moves error creation helpers scattered around
under lib/ into lib/internal/errors.js in the hope of being clearer
about the differences of errors that we throw into the user land.
- Move util._errnoException and util._exceptionWithHostPort
into internal/errors.js and simplify their logic so it's
clearer what the properties these helpers create.
- Move the errnoException helper in dns.js to internal/errors.js
into internal/errors.js and rename it to dnsException. Simplify
it's logic so it no longer calls errnoException and skips
the unnecessary argument checks.

The current default formatting is not ideal and this improves

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.

- Optimized (boxed) primitive handling
- Inline code if possible
- Only check extra keys if necessary
- Guard against unnecessary more expensive calls

By default, with small-icu, only the UTF-8, UTF-16le and UTF-16be decoders
are supported. With full-icu enabled, every encoding other than iso-8859-16
is supported.
This provides a basic test, but does not include the full web platform
tests. Note: many of the web platform tests for this would fail by default
because we ship with small-icu by default.
A process warning will be emitted on first use to indicate that the
API is still experimental. No runtime flag is required to use the
