This implements a nested event loop that makes it possible to control
a child process, while blocking the main loop until the process exits.

Mitigate C++-land assertion error, add test accordingly.

Fix #7070

Don't use argument as callback if it's not a valid callback function.
Throw a valid exception instead explaining the issue.

Adds to #7070 ("DNS — Throw meaningful error(s)").

The number of connections achieved by the test can vary by platform
and by machine. Lowering the acceptance threshold so that the
test passes on Windows.

fix #7070

Make vm.runInContext() and vm.runInNewContext() stop copying the Proxy
object from the parent context into the new context when --harmony or
--harmony_proxies is in effect because it overwrites the new context's
native Proxy object.

This commit also adds a regression test for Harmony symbols.  They work
okay in the current implementation and the test should ensure it stays
that way.

Conditional globals like 'gc' should only be recognized when --expose_gc
is set.  The global.gc feature check works only when done eagerly, else
it lets through a leaked variable called 'gc'.

Before, `new String('foo')` would be inspected as `"{}"` which
is simply not very helpful. Now, a more meaningful
`"[String: 'foo']"` result will be returned from `util.inspect()`.

Boxed String, Boolean, and Number types are all supported.

Closes #7047

Try embedding the ` ... ^` lines inside the `SyntaxError` (or any other
native error) object before giving up and printing them to the stderr.

The AsyncListener API has been moved into the "tracing" module in order
to keep the process object free from unnecessary clutter.

Now the second field in asyncFlags will tell if the provider is
currently being watched, or listened for.

These will be used to allow users to filter for which types of calls
they wish their callbacks to run.

"flags" could mean one of many things, and multiple flag types could be
checked. So make the field more explicit on what type of flags are being
stored.

Add a one-to-one binding to v8::GetHeapStatistics().  Returns info on
the current state of the JS heap, like total size and amount used.

Add a new 'tracing' module with a v8 property that lets the user
register listeners for gc events.  The listeners are invoked after
every garbage collection cycle with 'before' and 'after' statistics.
Useful for monitoring tools that want to keep track of memory usage.

Create a new HandleScope before looking up the object context with
v8::Object::CreationContext(), else we leak the Local<Context> into
the current HandleScope.

That's relatively harmless unless the HandleScope is long-lived and
MakeCallback() is called a lot.  In a scenario like that, we may end
up leaking a lot of memory.

What is unfortunate about this change is that we're trying hard to
eradicate the node_isolate global.  Longer term, we will probably have
to change the MakeCallback() prototype to one that requires an explicit
v8::Isolate* argument.

Make it possible to invoke MakeCallback() on a v8::Value but only for
the variant that takes a v8::Function as the thing to call.

The const char* and v8::String variants still require a v8::Object
because the function to call is looked up as a property on the receiver,
but that only works when the receiver is an object, not a primitive.

Introduce `ticketKeys` server option, `session` client option,
`getSession()` and `getTLSTicket()` methods.

Try to be consistent with v0.10 and emit "Maximum call stack size
reached", even if it happens when allocating context or doing other
stuff.

fix #7045

If the call to writeBuffer completes asynchronously, we need to have
an oncomplete callback on the request object no matter what. The
writeQueueSize seems irrelvant to that regard.

Note that on Windows writeBuffer always completes asynchronously.
