This commit fixes a bug where the cluster module failed to propagate EADDRINUSE
errors.

When a worker starts a (net, http) server, it requests the listen socket from
its master who then creates and binds the socket.

Now, OS X and Windows don't always signal EADDRINUSE from bind() but instead
defer the error until a later syscall. libuv mimics this behaviour to provide
consistent behaviour across platforms but that means the worker could end up
with a socket that is not actually bound to the requested addresss.

That's why the worker now checks if the socket is bound, raising EADDRINUSE if
that's not the case.

Fixes #2721.

Use widechar versions in a couple of places.
Don't use C-style cast in C++ code.

CommandLineToArgvW doesn't behave exactly the same as the crt, which makes it useless.
This reverts commit ef032cbe.

The TLS protocol allows (and sometimes requires) clients to renegotiate the
session. However, renegotiation requires a disproportional amount of server-side
resources, particularly CPU time, which makes it a potential vector for
denial-of-service attacks.

To mitigate this issue, we keep track of and limit the number of renegotiation
requests over time, emitting an error if the threshold is exceeded.

It's possible for a new connection to be closed in the window between the
accept() syscall and the call to uv_accept(). Deal with it and move on, don't
assert.

Fixes #2733.

Hitherto undocumented option that lets the user select the list of ciphers to
use or exclude in a SSL/TLS session.

This test starts two clustered HTTP servers on the same port. It expects the
first cluster to succeed and the second cluster to fail with EADDRINUSE.

Commit 840229a8 forgot to update the debugger special case in lib/module.js

Fixes #2710.

use "vcbuild x64" to do x64 build of node.exe

This reverts commit 11d1eca9.

It sporadically (but reproducibly) triggers an assert inside V8:

  Fatal error in /path/to/node/deps/v8/src/isolate.cc, line 1857
  CHECK(CurrentPerIsolateThreadData()->isolate_ == this) failed

Needs further investigation.

Refs #2691.

Fixes #2678.

v8 requires a lock of each thread using the vm, but if none is
explicitly is created it will implicitly create one for you. This
creates issues when trying to build modules which use v8's
multi-threading features because there's no lock to unlock.

A ReadStream constructed from an existing file descriptor failed to start
reading automatically. Avoids a userspace call to ReadStream.prototype._read().

net-dns-error: specifc test for the net DNS issue.
http-dns-error: now it works for HTTPS as well.

The socket was never destroyed on DNS errors. This broke some clients, including
lib/https.js.

Add missing translator for node_dtrace_http_*_request_t types.

Fixes #2667.
