I introduced this module over a year ago in a pull request as the v8
module but it was quickly subsumed by the tracing module.

The tracing module was recently removed again and that is why this
commit introduces the v8 module again, including the new features it
picked up commits d23ac0ea and f8076c40.

Move the big endian to little endian conversion logic for UCS2 input
from src/string_bytes.cc to src/node_buffer.cc; StringSlice() is the
only function that actually needs it and with this commit, a second
copy is avoided on big endian architectures.

Introduce two-byte overloads of node::Encode() and StringBytes::Encode()
that ensure that the input is suitably aligned.

Revisits commit 535fec83 from yesterday.

Fix a regression that was introduced in commit a38b9178 by removing the
bad check.  Also rearrange the addon loading logic to ensure that the
list of pending addons remains in a consistent state when the shared
object fails to load; in particular, when an addon self-registers first,
then hits a dynamic linker error in a later constructor.

Fixes the following asserting when loading a .node shared object:

    node: ../src/node.cc:1944: void node::node_module_register(void*):
    Assertion `(modpending) != (nullptr)' failed.

Seen with g++ 4.9.2 on x86_64 Linux: a SIGSEGV is generated when the
input to v8::String::NewFromTwoByte() is not suitably aligned.

g++ 4.9.2 emits SSE instructions for copy loops.  That requires aligned
input but that was something StringBytes::Encode() did not enforce until
now.  Make a properly aligned copy before handing off the input to V8.

We could, as an optimization, check that the pointer is aligned on a
two-byte boundary but that is technically still UB; pointers-to-char
are allowed to alias other pointers but the reverse is not true:
a pointer-to-uint16_t that aliases a pointer-to-char is in violation
of the pointer aliasing rules.

Add documentation for the callback parameter of http.ClientRequest's and
http.ServerResponse's write and end methods.

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.

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.

C++ won't deoptimize like JS if specific conditional branches are

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.
