Merge branch 'v0.11.1-release'
Now working on 0.11.2
path: add path.isAbsolute(path)

An absolute path will always open the same location regardless of your
current working directory. For posix, this just means path.charAt(0) ===
'/', but on Windows it's a little more complicated.

Fixes joyent/node#5299.
V8: Upgrade to 3.18.1
v8: reapply floating patches
events: add EventEmitter.defaultMaxListeners

Class property that controls the maximum number of listeners for all
instances of EventEmitter.

Fixes #3014.

cluster: clean up lib/cluster.js

Clean up and DRY the cluster source code. Fix a few bugs while we're
here:

* Short-lived handles in long-lived worker processes were never
  reclaimed, resulting in resource leaks.

* Handles in the master process are now closed when the last worker
  that holds a reference to them quits. Previously, they were only
  closed at cluster shutdown.

* The cluster object no longer exposes functions/properties that are
  only valid in the 'other' process, e.g. cluster.fork() is no longer
  exported in worker processes.

So much goodness and still manages to reduce the line count from 590
to 320.
