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.
