Ruben Bridgewater b3e93a91eb util: do not escape single quotes if not necessary 
Right now util.inspect will always escape single quotes. That is not
necessary though in case the string that will be escaped does not
contain double quotes. In that case the string can simply be wrapped
in double quotes instead.
If the string contains single and double quotes and it does not
contain `${` as part of the string, backticks will be used instead.
That makes sure only very few strings have to escape quotes at all.
Thus it increases the readability of these strings.

Anna Henningsen db49589624 console,util: avoid pair array generation in C++ 
Use a plain `[key, value, key, value]`-style list instead
of an array of pairs for inspecting collections.

This also fixes a bug with `console.table()` where
inspecting a non-key-value `MapIterator` would have
led to odd results.

Teddy Katz 80496a5570 util: add inspect suffix to BigInt64Array elements 
This commit updates `util.inspect` to add an `n` suffix to BigInts that
appear in BigInt64Arrays. BigInts are formatted with an `n` suffix in
most cases, but this did not occur in BigInt64Arrays due to an apparent
oversight where the implementation of `inspect` for typed arrays assumed
that all typed array elements are numbers.

Anna Henningsen 849aaaeeb0 Revert "util: change util.inspect depth default" 
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.

- 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.

Joyee Cheung 4af1bba6d0 util: implement util.getSystemErrorName() 
Reimplement uv.errname() as internal/util.getSystemErrorName() to
avoid the memory leaks caused by unknown error codes
and avoid calling into C++ for the error names. Also
expose it as a public API for external use.

Ruben Bridgewater 8f153092d8 util: change %o depth default 
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.

Ruben Bridgewater b994b8eff6 util: change util.inspect depth default 
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.

Remove the custom formatter that was added in commit 4fb27d4 ("intl: Add
more versions from ICU").  It's not necessary anymore (and may not have
been necessary at all) and prevents proper coloring in the REPL.

Ruben Bridgewater c2203cb4dd util: add util.inspect compact option 
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}".
