  * Errors are emitted on process nextTick.

* **Domains**
  * The long-deprecated `.dispose()` method has been removed.

* **fs**
  * The `fs.ReadStream` and `fs.WriteStream` classes now use `destroy()`.
  * `fs` module callbacks are now invoked with an undefined context.

* **HTTP/1**
  * A 400 Bad Request response will now be sent when parsing fails.
  * Socket timeout will be set when the socket connects.
  * A bug causing the request `'error'` event to fire twice was fixed.
  * HTTP clients may now use generic `Duplex` streams in addition to `net.Socket`.

* **Intl**
  * The deprecated `Intl.v8BreakIterator` has been removed.

* **Modules**
  * The `require.resolve()` method now supports using custom lookup paths.

* **OS**
  * The `os.EOL` property is now read-only.

* **Timers**
  * `setTimeout()` will emit a warning if the timeout is larger that the maximum
    32-bit unsigned integer.

The original commit was landed without running CITGM. Unfortunately
this change breaks the module `d` which has over 500k downloads a day.

It is worth mentioning that the compatibility hack can be removed
without breaking anything.

We should definitely revisit for the next Semver-Major but shipping
this today will cause non trivial ecosystem breakages.

On 4 April 2017, Node.js versions v4.8.2 and v6.10.2 were
released. These versions bumped the vendored zlib library from
v1.2.8 to v1.2.11 in response to what it describes as low-severity
CVEs. In zlib v1.2.9, a change was made that causes an error to be
raised when a raw deflate stream is initialised with windowBits set
to 8.

In zlib v1.2.9, 8 become an invalid value for this parameter, and Node's zlib
module will crash if you call this:

```
zlib.createDeflateRaw({windowBits: 8})
```

On some versions this crashes Node and you cannot recover from it, while on some
versions it throws an exception. The permessage-deflate library up to
version v0.1.5 does make such a call with no try/catch

This commit reverts to the original behavior of zlib by gracefully changed
windowBits: 8 to windowBits: 9 for raw deflate streams.

* correctly reset write timers: currently reset timers on
  both session & stream when write starts and when it ends.
* prevent large writes from timing out: when writing a large
  chunk of data in http2, once the data is handed off to C++,
  the JS session & stream lose all track of the write and will
  timeout if the write doesn't complete within the timeout window
  Fix this issue by tracking whether a write request is ongoing and
  also tracking how many chunks have been sent since the most recent
  write started. (Since each write call resets the timer.)

Reduce the size of wrap objects by moving a couple of accessors from the
instance template to the prototype template.  They occupied one slot per
instance instead of one slot per class.

This commit fixes some instances of unwrapping twice since that code had
to be updated anyway to use `args.This()` instead of `args.Holder()`.
