With the new Ignition+TurboFan pipeline, the instanceof fast-path can be
missed if the right-hand side needs a TDZ check, i.e. is const declared
on a surrounding scope. This doesn't apply to Node 8 at this point,
where it's at V8 5.8, but it applies as soon as V8 5.9 rolls. There's
work going on in Ignition (and TurboFan) to optimize those TDZ checks
properly, but those changes will land in V8 6.1, so might not end up in
Node 8.
One way to work-around this in Node core for now is to use var instead
of const for those right-hand sides for instanceof for now, especially
Buffer in case of streams. This is not beautiful, but proper ducktape.
Improves readable-bigread.js by ~23% with Node LKGR.

In most cases, named functions match the variable or property to which
they are being assigned. That also seems to be the practice in a series
of PRs currently being evaluated that name currently-anonymous
functions.
This change applies that rule to instances in the code base that don't
comply with that practice.
This will be enforceable with a lint rule once we upgrade to ESLint
3.8.0.

Queued write requests should be invoked on handle close, otherwise the
"consumer" might be already destroyed when the write callbacks of the
"consumed" handle will be invoked. Same applies to the shutdown
requests.
Make sure to "move" away socket from server to not break the
`connections` counter in `net.js`. Otherwise it might not call `close`
callback, or call it too early.

Introduce a way to wrap plain-js `stream.Duplex` streams into C++
StreamBase's child class. With such method at hand it is now possible to
pass `stream.Duplex` instance as a `socket` parameter to
`tls.connect()`.
