Several changes:
* Soft-Deprecate Buffer() constructors
* Add `Buffer.from()`, `Buffer.alloc()`, and `Buffer.allocUnsafe()`
* Add `--zero-fill-buffers` command line option
* Add byteOffset and length to `new Buffer(arrayBuffer)` constructor
* buffer.fill('') previously had no effect, now zero-fills
* Update the docs

`Console` constructor checks that `stdout.write()` is a function but
does not do an equivalent check for `stderr.write()`. If `stderr` is not
specified in the constructor, then `stderr` is set to be `stdout`.
However, if `stderr` is specified, but `stderr.write()` is not a
function, then an exception is not thrown until `console.error()` is
called.
This change adds the same check for 'stderr' in the constructor that is
there for `stdout`. If `stderr` fails the check, then a `TypeError` is
thrown.
Took the opportunity to copyedit the `console` doc a little too.

`isIPv4` and `isIPv6` are implemented on top of `isIP`, which in turn
checks the sting for being both IPv4 and IPv6, which can be inefficient
in some scenarios. This commit makes them use `uv_inet_pton` directly
instead.

The current documentation for Convenience Methods specifies that
the first argument can be either
`string or buffer`, `string` or `raw Buffer`.
This commit replaces all these instances with `Buffer or string`.

The current documentation for writable.write only specifies that the
callback is called "once the data has been fully handled". It is
ambiguous whether this means "successfully handled" and, if so,
whether the callback is called if the data can not be successfully
handled (i.e. an error occurs).
The ambiguity is not only in the documentation. The stream class
implementations differ on this point. stream.Writable invokes the
callback with any errors that occur during parameter checking or
during calls to _write. However, not all classes return all errors
to _write. zlib.Zlib does pass argument and state errors to the
_write (_transform) callback, but does not pass data errors.
http.OutgoingMessage passes argument type errors and some other types
of errors, but not all.
This inconsistency is behind issue #1746 and, I suspect, other issues
in client code which passes a callback to write.
This commit takes no position on whether the callback error behavior
should changed, but simply attempts to document the current behavior
in a way that is open to changes so that users are not caught by
surprise.

This commit updates events doc to describe removeListener behaviour
when it is called within a listener. An example is added to make
it more evident.
A test is also incuded to make this behaviour consistent in future
releases.

Instead of leaking the arguments object by passing it as an
argument to a function, copy it's contents to a new array,
then pass the array. This allows V8 to optimize the function
that contains this code, improving performance.

In December we announced that we would be doing a minor release in order to
get a number of voted on SEMVER-MINOR changes into LTS. Our ability to release this
was delayed due to the unforeseen security release v4.3. We are quickly bumping to
v4.4 in order to bring you the features that we had committed to releasing.
This release also includes over 70 fixes to our docs and over 50 fixes to tests.
The SEMVER-MINOR changes include:
* deps:
- An update to v8 that introduces a new flag --perf_basic_prof_only_functions (Ali Ijaz Sheikh) https://github.com/nodejs/node/pull/3609
* http:
- A new feature in http(s) agent that catches errors on *keep alived* connections (José F. Romaniello) https://github.com/nodejs/node/pull/4482
* src:
- Better support for Big-Endian systems (Bryon Leung) https://github.com/nodejs/node/pull/3410
* tls:
- A new feature that allows you to pass common SSL options to `tls.createSecurePair` (Коренберг Марк) https://github.com/nodejs/node/pull/2441
* tools
- a new flag `--prof-process` which will execute the tick processor on the provided isolate files (Matt Loring) https://github.com/nodejs/node/pull/4021
Notable semver patch changes include:
* buld:
- Support python path that includes spaces. This should be of particular interest to our Windows users who may have python living in `c:/Program Files` (Felix Becker) https://github.com/nodejs/node/pull/4841
* https:
- A potential fix for https://github.com/nodejs/node/issues/3692 HTTP/HTTPS client requests throwing EPROTO (Fedor Indutny) https://github.com/nodejs/node/pull/4982

- More readable profiling information from isolate tick logs (Matt Loring) https://github.com/nodejs/node/pull/3032
* *npm:
- upgrade to npm 2.14.20 (Kat Marchán) https://github.com/nodejs/node/pull/5510

* querystring:
- querystring.parse() is now 13-22% faster! (Brian White) https://github.com/nodejs/node/pull/4675
* streams:
- performance improvements for moving small buffers that shows a 5% throughput gain. IoT projects have been seen to be as much as 10% faster with this change! (Matteo Collina) https://github.com/nodejs/node/pull/4354
