Currently, cluster workers can be removed from the workers list in three
different places:
- In the exit event handler for the worker process.
- In the disconnect event handler of the worker process.
- In the disconnect event handler of the cluster master.
However, handles for a given worker are cleaned up only in one of these
places: in the cluster master's disconnect event handler.
Because these events happen asynchronously, it is possible that the
workers list is empty before we even clean up one handle. This makes
the assert that makes sure that no handle is left when the workers
list is empty fail.
This commit removes the worker from the cluster.workers list only when
the worker is dead _and_ disconnected, at which point we're sure that
its associated handles are cleaned up.
Fixes#8191 and #8192.

The slot 0 and 1 had already been taken by "gin" and "blink" in Chrome,
and the size of isolate's slots is 4 by default, so using 3 should hopefully
make node work independently when embedded into other application.

- *NOTE* this introduces a breaking change, previously you could construct

UTF-8, now unmatched surrogate pairs are replaced with the unknown UTF-8
character. To restore the old functionality simply have NODE_INVALID_UTF8
environment variable set.

Previously v8's WriteUtf8 function would produce invalid utf-8 output
when encountering unmatched surrogate code units [1]. The new
REPLACE_INVALID_UTF8 option fixes that by replacing invalid code points
with the unicode replacement character.
[1]: JS Strings are defined as arrays of 16 bit unsigned integers. There
is no unicode enforcement, so one can easily end up with invalid unicode
code unit sequences inside a string.
Replace the CONTAINER_OF macro with a template function that is as
type-safe as a reinterpret_cast<> of an arbitrary pointer can be made.

Otherwise it's not possible to check from inside a destructor if V8 is
still alive with v8::V8::IsDead(). In V8 3.25, that function returns
true until the last isolate is destroyed.
This used to work in v0.10 and is a standard trick to dispose persistent
handles conditionally.

dispose() free's the memory when executed and sets the external array
data to NULL and length to zero.
To prevent the same memory from being free'd twice when the object is
garbage collected we first check if the object's external array data
length == 0. Since alloc() passes NULL to
SetIndexedPropertiesToExternalArrayData() if length == 0 there's no
opportunity for memory leak.
