2015-02-10 io.js v1.2.0 Release

Notable changes:

* stream:
  - Simpler stream construction, see
    https://github.com/iojs/readable-stream/issues/102 for details.
    This extends the streams base objects to make their constructors
    accept default implementation methods, reducing the boilerplate
    required to implement custom streams. An updated version of
    readable-stream will eventually be released to match this change
    in core. (@sonewman)
* dns:
  - `lookup()` now supports an `'all'` boolean option, default to
    `false` but when turned on will cause the method to return an
    array of *all* resolved names for an address, see,
    https://github.com/iojs/io.js/pull/744 (@silverwind)
* assert:
  - Remove `prototype` property comparison in `deepEqual()`,
    considered a bugfix, see https://github.com/iojs/io.js/pull/636
    (@vkurchatkin)
  - Introduce a `deepStrictEqual()` method to mirror `deepEqual()`
    but performs strict equality checks on primitives, see
    https://github.com/iojs/io.js/pull/639 (@vkurchatkin)
* **tracing**:
  - Add LTTng (Linux Trace Toolkit Next Generation) when compiled
    with the  `--with-lttng` option. Trace points match those
    available for DTrace and ETW.
