This saves a few calls to gettimeofday which can be expensive, and
potentially subject to clock drift. Instead use the loop time which
uses hrtime internally.

fixes #5497

Now that Context::New(Isolate*) returns Local, the removed comment is
no longer applicable that there is a Persistent which will need to be
disposed.

Small change that Context::New requires an isolate and returns Local
instead of Persistent.

Fixes #5499

Because of variations in different base64 implementation, it's been
decided to strip all padding from the end of a base64 string and
calculate its size from that.

Add localAddress and localPort properties to tls.CleartextStream.
Like remoteAddress and localPort, delegate to the backing net.Socket
object.

* uv: upgrade to v0.10.7

* npm: Upgrade to 1.2.21

* crypto: Don't ignore verify encoding argument (isaacs)

* buffer, crypto: fix default encoding regression (Ben Noordhuis)

* timers: fix setInterval() assert (Ben Noordhuis)

Instead of String::New every time, use a Persistent sym. This can be
accomplished in two ways:

1) Local<String> str = *persistent_str_sym;

2) Handle<String> str = persistent_str_sym;

I've chosen to use the latter method for simplicity's sake.

Other small changes include creating syms on Initialize and removing
unnecessary Local casting on return values.

Few primitives weren't being passed node_isolate. Adding them for
consistency.

The default encoding is 'buffer'. When the input is a string, treat it
as 'binary'. Fixes the following assertion:

  node: ../src/string_bytes.cc:309: static size_t
  node::StringBytes::StorageSize(v8::Handle<v8::Value>, node::encoding):
  Assertion `0 && "buffer encoding specified but string provided"'
  failed.

Introduced in 64fc34b2.

Fixes #5482.

The incoming Buffer was being sliced just to possibly not be used.
Instead place the .slice inside the conditional to not be created unless
necessary.

Test case:

  var t = setInterval(function() {}, 1);
  process.nextTick(t.unref);

Output:

  Assertion failed: (args.Holder()->InternalFieldCount() > 0),
  function Unref, file ../src/handle_wrap.cc, line 78.

setInterval() returns a binding layer object. Make it stop doing that,
wrap the raw process.binding('timer_wrap').Timer object in a Timeout
object.

Fixes #4261.

Instead of using a custom solution for path delimiters we can use
path.sep in Module._initPaths

Commit 38149bb0 changes http.get() and http.request() to escape unsafe
characters. However, that creates an incompatibility with v0.10 that
is difficult to work around: if you escape the path manually, then in
v0.11 it gets escaped twice. Change lib/http.js so it no longer tries
to fix up bad request paths, simply reject them with an exception.

The actual check is rather basic right now. The full check for illegal
characters is difficult to implement efficiently because it requires a
few characters of lookahead. That's why it currently only checks for
spaces because those are guaranteed to create an invalid request.

Fixes #5474.

net.connect() and net.createConnection() now emit a 'lookup' event
after resolving the hostname but before connecting.

Fixes #5418.

Please msbuild, update the header list.

While they reference the same object, they are only interchangeable
for updates, not assignment.

When exporting a single function you must use `module.exports` instead
of the `exports` convenience reference.
