Changes the custom inspect example to a more complex object that
actually uses the parameters of the custom inspect function. I
specifically chose a wrapper of a value called a "Box" that inspects
to "Box < inner_inspect_value >".
I also want there to be documentation explaining what the code is
actually doing. E.g., the padding replacement part is to make the
inspected value line up properly when multi-line inputs are given.
I also went with having a space between the Box's brackets and the inner
value because it matches how objects work, and that should definitely be
listed as a convention somewhere in here.
Also, the convention to shorten only when depth is less than 0, not e.g.
at 0.
But I don't know how to write the documentation for that, so I'm leaving
that to somebody who reads this message.

Until now, the docs stated that `process.noDeprecation` could be set
at runtime, but before any modules were loaded. That was not true,
because `lib/internal/util.js` was loaded during the process startup
process, so setting the flag at runtime was pointless.
Minimal test case:
process.noDeprecation = true;
process.EventEmitter;
This patch moves checking `process.noDeprecation` to the place where
it was actually used.
