node: fix bad assert

the assert was originally done.

test: runner support for flaky tests

Adding --flaky-tests option, to allow regarding flaky tests failures
as non-fatal.

Currently only observed by the TapProgressIndicator, which will
add a # TODO directive to tests classified as flaky. According to the
TAP specification, the test harness is supposed to treat failures
that have a # TODO directive as non-fatal.
test: mark current flaky tests as flaky
src: remove Async Listener

Async Listener was the name of the user-facing JS API, and is being
completely removed. Instead low level hooks directly into the mechanism
that AL used will be introduced in a future commit.

async-wrap: move MakeCallback to .cc

MakeCallback is too large a function to be inlined. Likewise, only
having header files will not allow for any part of AsyncWrap to be
exposed cleanly via NODE_MODULE_CONTEXT_AWARE_BUILTIN().

node, async-wrap: remove MakeDomainCallback

C++ won't deoptimize like JS if specific conditional branches are
sporadically met in the future. Combined with the amount of code
duplication removal and simplified maintenance complexity, it makes more
sense to merge MakeCallback and MakeDomainCallback.

Additionally, type casting in V8 before verifying what that type is will
cause V8 to abort in debug mode if that type isn't what was expected.
Fix this by first checking the v8::Value before casting.

src: all wrap's now use actual FunctionTemplate

Instead of simply creating a new v8::Object to contain the connection
information, instantiate a new instance of a FunctionTemplate. This will
allow future improvements for debugging and performance probes.

Additionally, the "provider" argument in the ReqWrap constructor is no
longer optional.

async-wrap: expose async-wrap as binding

Expose basic hooks for AsyncWrap via the async_wrap binding. Right now
only the PROVIDER types are exposed. This is a preliminary step before
more functionality is added.

async-wrap: explicitly pass parent

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.

async-wrap: add event hooks

Call a user-defined callback at specific points in the lifetime of an
asynchronous event. Which are on instantiation, just before/after the
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
those will be added in a future commit.

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.

Dtrace probes were removed from libuv recently, but their usage by node
was not completely removed, causing build breaks on SmartOS.

Even though the build is working on other platforms, these probes are
not fired by libuv anymore, so there's no point in using them on these
platforms too.

cluster: don't assume all workers bind same ports

For shared handles that do not get connection close messages (UDP/dgram
is the only example of this), cluster must not assume that a port
listened on by one worker is listened on by all workers.
cluster: cluster.disconnect() should check status

Workers that are already disconnected but not yet exited should not be
disconnected, trying to do so raises exceptions.
dgram: implicit binds should be exclusive

Server sockets should be shared by default, and client sockets should be
exclusive by default. For net/TCP, this is how it is, for dgram/UDP, its
a little less clear what a client socket is, but a socket that is
auto-bound during a dgram.send() is not usefully shared among cluster
workers, any more than an outgoing TCP connection would be usefully
shared.
