This is the Node side of the fix for Node's cluster module on Windows.

The other required part is
https://github.com/joyent/libuv/pull/1384
Windows and Unix return certain socket errors (i.e. EADDRINUSE) at
different times: bind on Windows, and listen on Unix.
In an effort to hide this difference, libuv on Windows stores such
errors in the bind_error field of uv_tcp_t, to defer raising it at
listen time.
This worked fine except for the case in which a socket is shared in
a Node cluster and a bind error occurs.
A previous attempt to fix this (
d1e6be14603da36fe00e
) was flawed becaused in an attempt to relay the error at the JS level
it caused the master to start accepting connections.
With this new approach, libuv itself is relaying the bind errors,
providing for a uniform behavior of uv_tcp_listen.

Switch condition order to check for null before calling isNaN().
Also remove two unnecessary calls to isNaN() that are already
covered by calls to isFinite(). This commit targets v0.10, as
opposed to #7891, which targets master (suggested by
@bnoordhuis). Closes#7840.

net.server.listen() behaves inconsistently depending on whether the port
number is provided.
1. port === 0 && host == '' (i.e. false-y), node creates an AF_INET
socket but does not call bind().
2. port > 0 && host == '', node creates an AF_INET6 socket and calls
bind().
The fix makes 1 consistent with 2.

When close() is called on a non-listening server, a synchronous
error is thrown. This commit causes the error to be passed to
the asynchronous callback function instead.

Expose `setBlocking` on Pipe's and if a pipe is being created for stdio
on windows then make the pipes blocking.
This fixes test-stream2-stderr-sync.js on Windows.
Fixes#3584
Expose localPort for binding to a specific port for outbound
connections.
If localAddress is not specified '0.0.0.0' is used for ip4 and '::'
for ip6 connections.
Fixes#7092
Before sending a socket from a cluster master to a worker,
we would call listen in UV but not handle the error.
I made createServerHandle call listen on Windows so we get a chance
the handle any bind/listen errors early.
This fix is 100% windows specific.
It fixes test-cluster-bind-twice and
test-cluster-shared-handle-bind-error on Windows.
This is a slightly modified revert of bc39bdd.
Getting domains to use AsyncListeners became too much of a challenge
with many edge cases. While this is still a goal, it will have to be
deferred for now until more test coverage can be provided.
The domain module has been switched over to use the domain module API as
much as currently possible. There are still some hooks in the
EventEmitter, but hopefully we can remove those in the future.
When `tls.connect()` is called with `socket` option, it should try to
reuse hostname previously passed to `net.connect()` and only after that
fall back to `'localhost'`.

`dns.lookup` defaults to selecting IPv4 record even if IPv6 is available
for the desired zone. Generally, this approach works, but if IPv4
address is unavailable - there'll be no other way to opt-out and connect using
IPv6 address than calling `dns.lookup` and passing it to `.connect()`
directly.
This commit adds `family` option to `net.connect` method to figure out
this issue.
Don't use v8::Object::SetHiddenValue() to keep a reference alive to the
buffer, we can just as easily do that from JS land and it's a lot faster
to boot.
Because the buffer is now a visible property of the write request
object, it's essential that we do *not* log it - we'd be effectively
serializing the whole buffer to a pretty-printed string.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
This is a big commit that touches just about every file in the src/
directory. The V8 API has changed in significant ways. The most
important changes are:
* Binding functions take a const v8::FunctionCallbackInfo<T>& argument
rather than a const v8::Arguments& argument.
* Binding functions return void rather than v8::Handle<v8::Value>. The
return value is returned with the args.GetReturnValue().Set() family
of functions.
* v8::Persistent<T> no longer derives from v8::Handle<T> and no longer
allows you to directly dereference the object that the persistent
handle points to. This means that the common pattern of caching
oft-used JS values in a persistent handle no longer quite works,
you first need to reconstruct a v8::Local<T> from the persistent
handle with the Local<T>::New(isolate, persistent) factory method.
A handful of (internal) convenience classes and functions have been
added to make dealing with the new API a little easier.
The most visible one is node::Cached<T>, which wraps a v8::Persistent<T>
with some template sugar. It can hold arbitrary types but so far it's
exclusively used for v8::Strings (which was by far the most commonly
cached handle type.)
This is only relevant for CentOS 6.3 using kernel version 2.6.32.
On other linuxes and darwin, the `read` call gets an ECONNRESET in that
case. On sunos, the `write` call fails with EPIPE.
However, old CentOS will occasionally send an EOF instead of a
ECONNRESET or EPIPE when the client has been destroyed abruptly.
Make sure we don't keep trying to write or read more in that case.
Fixes#5504
However, there is still the question of what libuv should do when it
gets an EOF. Apparently in this case, it will continue trying to read,
which is almost certainly the wrong thing to do.
That should be fixed in libuv, even though this works around the issue.
Buffer.byteLength() works only for string inputs. Thus, when connection
has pending Buffer to write, it should just use it's length instead of
throwing exception.
