Reduce the overhead of the CPU profiler by suppressing SIGPROF signals
when sleeping / polling for events. Avoids unnecessary wakeups when the
CPU profiler is active.
The benefits are quite substantial on systems where it is expensive to
query the system time (most virtualized environments). Before, it was
common to see over 20% of wall clock time being spent on clock_gettime()
system calls.

Instead of installing an early debug signal handler, simply block the
SIGUSR1 signal at start-up and unblock it when the debugger is ready.
Both approaches are functionally equivalent but blocking the signal
accomplishes it in fewer lines of code.

Execute the per-platform initialization logic as early as possible,
for two reasons:
1. It opens the way for an upcoming commit to simplify early SIGUSR1

2. It should make life easier for embedders because io.js no longer

of the process.

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.

Mark the matrix of copy/move constructor/assignment operator as deleted.
Prevents the object from being copied around (the macro already did that
pre-C++11), but also from being moved out.
Add `override` keywords where appropriate. Makes maintenance easier
because the compiler will shout at you when a base class changes in
an incompatible way.
Now that we are building with C++11 features enabled, replace use
of NULL with nullptr.
The benefit of using nullptr is that it can never be confused for
an integral type because it does not support implicit conversions
to integral types except boolean - unlike NULL, which is defined
as a literal `0`.
Attach the per-context execution environment directly to API functions.
Rationale:
* Gets node one step closer to multi-isolate readiness.
* Avoids multi-context confusion, e.g. when the caller and callee live
in different contexts.
* Avoids expensive calls to pthread_getspecific() on platforms where
V8 does not know how to use the thread-local storage directly.
