Make `HTTPParser` an instance of `AsyncWrap` and make it use
`MakeCallback`. This means that async wrap hooks will be called on
consumed TCP sockets as well as on non-consumed ones.
Additional uses of `AsyncCallbackScope` are necessary to prevent
improper state from progressing that triggers failure in the
test-http-pipeline-flood.js test. Optimally this wouldn't be necessary,
but for the time being it's the most sure way to allow operations to
proceed as they have.

Call a user's callback to notify that the handle has been destroyed.
Only pass the id of the AsyncWrap instance since the object no longer
exists.
The object that's being destructed should never be inspected within the
callback or any time afterward.
This commit make a breaking change. The init callback will now be passed
arguments in the order of provider, id, parent.

New instances of AsyncWrap are automatically assigned a unique id. The
value will be used in future commits to communicate additional
information via the async hooks.
While the largest value we can reliably communicate to JS is 2^53, even
if a new AsyncWrap is created every 100ns the uid won't reach its end
for 28.5 years.

Previous logic didn't allow parent to propagate to the init callback
properly. The fix now allows the init callback to be called and receive
the parent if:
- async wrap callbacks are enabled and parent exists
- the init callback has been called on the parent and an init callback
exists then it will be called regardless of whether async wrap
callbacks are disabled.
Change the init/pre/post callback checks to see if it has been properly
set. This allows removal of the Environment "using_asyncwrap" variable.

Call a user-defined callback at specific points in the lifetime of an

callback has been run.
**If any of these callbacks throws an exception, there is no forgiveness
or recovery. A message will be displayed and a core file dumped.**
Currently these only tie into AsyncWrap, meaning no call to a hook
callback will be made for timers or process.nextTick() events. Though

Here are a few notes on how to make the hooks work:
- The "this" of all event hook callbacks is the request object.
- The zero field (kCallInitHook) of the flags object passed to
setupHooks() must be set != 0 before the init callback will be called.
- kCallInitHook only affects the calling of the init callback. If the
request object has been run through the create callback it will always
run the before/after callbacks. Regardless of kCallInitHook.
- In the init callback the property "_asyncQueue" must be attached to
the request object. e.g.
function initHook() {
this._asyncQueue = {};
}
- DO NOT inspect the properties of the object in the init callback.
Since the object is in the middle of being instantiated there are some
cases when a getter is not complete, and doing so will cause Node to
crash.

When instantiating a new AsyncWrap allow the parent AsyncWrap to be
passed. This is useful for cases like TCP incoming connections, so the
connection can be tied to the server receiving the connection.
Because the current architecture instantiates the *Wrap inside a
v8::FunctionCallback, the parent pointer is currently wrapped inside a
new v8::External every time and passed as an argument. This adds ~80ns
to instantiation time.
A future optimization would be to add the v8::External as the data field
when creating the v8::FunctionTemplate, change the pointer just before
making the call then NULL'ing it out afterwards. This adds enough code
complexity that it will not be attempted until the current approach
demonstrates it is a bottle neck.

Make AsyncWrap::~AsyncWrap() virtual, otherwise it is unsafe to delete
a derived class through a pointer to AsyncWrap. Fortunately, we don't
do that anywhere right now; this commit is merely a preemptive bug fix.

The ability to add/remove an AsyncListener to an object after its
creation was an artifact of trying to get AL working with the domain
module. Now that is no longer necessary and other features are going to
be implemented that would be affected by this functionality. So the code
will be removed for now to simplify the implementation process.
In the future this code will likely be reintroduced, but after some
other more important matters have been addressed.
None of this functionality was documented, as is was meant specifically
for domain specific implementation work arounds.

Before when an AsyncListener object was created and the "create"
callback returned a value, it was necessary to construct a new Object
with the same callbacks but add a place for the new storage value.
Now, instead, a separate storage array is kept on the context which is
used for any return value of the "create" callback. This significantly
reduces the number of Objects that need to be created.
Also added a flags property to the context to quickly check if a
specific callback was available either on the context or on the
AsyncListener instance itself.
Few other minor changes for readability that were difficult to separate
into their own commit.
This has not been optimized yet.
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.
BaseObject is a class that just handles the Persistent handle attached
to the class instance.
This also removed WeakObject. Reordering the inheritance chain helps
prevent unneeded calls on instances that don't call MakeCallback.
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.
AsyncListener is a JS API that works in tandem with the AsyncWrap class
to allow the user to be alerted to key events in the life cycle of an
asynchronous event. The AsyncWrap class has its own MakeCallback
implementation that core will be migrated to use, and uses state sharing
techniques to allow quicker communication between JS and C++ whether the
async event callbacks need to be called.
