src: refactor uncaught exception handling
The C++ land `node::FatalException()` is not in fact fatal anymore.
It gives the user a chance to handle the uncaught exception
globally by listening to the `uncaughtException` event. This patch
renames it to `TriggerUncaughtException` in C++ to avoid the confusion.

In addition rename the JS land handler to `onGlobalUncaughtException`
to reflect its purpose - we have to keep the alias
`process._fatalException` and use that for now since it has been
monkey-patchable in the user land.

This patch also

- Adds more comments to the global uncaught exception handling routine
- Puts a few other C++ error handling functions into the `errors`
  namespace
- Moves error-handling-related bindings to the `errors` binding.

src: refactor BaseObject internal field management
- Instead of storing a pointer whose type refers to the specific
  subclass of `BaseObject`, just store a `BaseObject*` directly.
  This means in particular that one can cast to classes along
  the way of the inheritance chain without issues, and that
  `BaseObject*` no longer needs to be the first superclass
  in the case of multiple inheritance.

  In particular, this renders hack-y solutions to this problem (like
  ddc19be6de) obsolete and addresses
  a `TODO` comment of mine.

- Move wrapping/unwrapping methods to the `BaseObject` class.
  We use these almost exclusively for `BaseObject`s, and I hope
  that this gives a better idea of how (and for what) these are used
  in our code.

- Perform initialization/deinitialization of the internal field
  in the `BaseObject*` constructor/destructor. This makes the code
  a bit more obviously correct, avoids explicit calls for this
  in subclass constructors, and in particular allows us to avoid
  crash situations when we previously called `ClearWrap()`
  during GC.

  This also means that we enforce that the object passed to the
  `BaseObject` constructor needs to have an internal field.
  This is the only reason for the test change.

- Change the signature of `MakeWeak()` to not require a pointer
  argument. Previously, this would always have been the same
  as `this`, and no other value made sense. Also, the parameter
  was something that I personally found somewhat confusing
  when becoming familiar with Node’s code.

- Add a `TODO` comment that motivates switching to real inheritance
  for the JS types we expose from the native side. This patch
  brings us a lot closer to being able to do that.

- Some less significant drive-by cleanup.

Since we *effectively* already store the `BaseObject*` pointer
anyway since ddc19be6de, I do not
think that this is going to have any impact on diagnostic tooling.

src: refactor WriteWrap and ShutdownWraps
Encapsulate stream requests more:

- `WriteWrap` and `ShutdownWrap` classes are now tailored to the
  streams on which they are used. In particular, for most streams
  these are now plain `AsyncWrap`s and do not carry the overhead
  of unused libuv request data.
- Provide generic `Write()` and `Shutdown()` methods that wrap
  around the actual implementations, and make *usage* of streams
  easier, rather than implementing; for example, wrap objects
  don’t need to be provided by callers anymore.
- Use `EmitAfterWrite()` and `EmitAfterShutdown()` handlers to
  call the corresponding JS handlers, rather than always trying
  to call them. This makes usage of streams by other C++ code
  easier and leaner.

Also fix up some tests that were previously not actually testing
asynchronicity when the comments indicated that they would.

src: minor refactoring to StreamBase writes
Instead of having per-request callbacks, always call a callback
on the `StreamBase` instance itself for `WriteWrap` and `ShutdownWrap`.

This makes `WriteWrap` cleanup consistent for all stream classes,
since the after-write callback is always the same now.

If special handling is needed for writes that happen to a sub-class,
`AfterWrite` can be overridden by that class, rather than that
class providing its own callback (e.g. updating the write
queue size for libuv streams).

If special handling is needed for writes that happen on another
stream instance, the existing `after_write_cb()` callback
is used for that (e.g. custom code after writing to the
transport from a TLS stream).

As a nice bonus, this also makes `WriteWrap` and `ShutdownWrap`
instances slightly smaller.

src: remove StreamResourc::Cast()
This is not necessary since C++ already has `static_cast`
as a proper way to cast inside a class hierarchy.

src: explicitly register built-in modules
Previously, built-in modules are registered before main() via
__attribute__((constructor)) mechanism in GCC and similiar
mechanism in MSVC. This causes some issues when node is built as
static library. Calling module registration function for built-in
modules in node::Init() helps to avoid the issues.

src: implement native changes for async_hooks
Changes in the native code for the upcoming async_hooks module. These
have been separated to help with review and testing.

Changes include:

* Introduce an async id stack that tracks recursive calls into async
  execution contexts. For performance reasons the id stack is held as a
  double* and assigned to a Float64Array. If the stack grows too large
  it is then placed in it's own stack and replaced with a new double*.
  This should accommodate arbitrarily large stacks.

  I'm not especially happy with the complexity involved with this async
  id stack, but it's also the fastest and most full proof way of
  handling it that I have found.

* Add helper functions in Environment and AsyncWrap to work with the
  async id stack.

* Add AsyncWrap::Reset() to allow AsyncWrap instances that have been
  placed in a resource pool, instead of being released, to be
  reinitialized. AsyncWrap::AsyncWrap() also now uses Reset() for
  initialization.

* AsyncWrap* parent no longer needs to be passed via the constructor.

* Introduce Environment::AsyncHooks class to contain the needed native
  functionality. This includes the pointer to the async id stack, and
  array of v8::Eternal<v8::String>'s that hold the names of all
  providers, mechanisms for storing/retrieving the trigger id, etc.

* Introduce Environment::AsyncHooks::ExecScope as a way to track the
  current id and trigger id of function execution via RAII.

* If the user passes --abort-on-uncaught-exception then instead of
  throwing the application will print a stack trace and abort.

async_wrap,src: add GetAsyncId() method
Allow handles to retrieve their own uid's by adding a new method on the
FunctionTemplates. Implementation of these into all other classes will
come in a future commit.

Add the method AsyncWrap::GetAsyncId() to all inheriting class objects
so the uid of the handle can be retrieved from JS.

In all applicable locations, run ClearWrap() on the object holding the
pointer so that it never points to invalid memory and make sure Wrap()
is always run so the class pointer is correctly attached to the object
and can be retrieved so GetAsyncId() can be run.

In many places a class instance was not removing its own pointer from
object() in the destructor. This left an invalid pointer in the JS
object that could cause the application to segfault under certain
conditions.

Remove ClearWrap() from ReqWrap for continuity. The ReqWrap constructor
was not the one to call Wrap(), so it shouldn't be the one to call
ClearWrap().

Wrap() has been added to all constructors that inherit from AsyncWrap.
Normally it's the child most class. Except in the case of HandleWrap.
Which must be the constructor that runs Wrap() because the class pointer
is retrieved for certain calls and because other child classes have
multiple inheritance to pointer to the HandleWrap needs to be stored.

ClearWrap() has been placed in all FunctionTemplate constructors so that
no random values are returned when running getAsyncId(). ClearWrap() has
also been placed in all class destructors, except in those that use
MakeWeak() because the destructor will run during GC. Making the
object() inaccessible.

It could be simplified to where AsyncWrap sets the internal pointer,
then if an inheriting class needs one of it's own it could set it again.
But the inverse would need to be true also, where AsyncWrap then also
runs ClearWeak. Unforunately because some of the handles are cleaned up
during GC that's impossible. Also in the case of ReqWrap it runs Reset()
in the destructor, making the object() inaccessible. Meaning,
ClearWrap() must be run by the class that runs Wrap(). There's currently
no generalized way of taking care of this across all instances of
AsyncWrap.

I'd prefer that there be checks in there for these things, but haven't
found a way to place them that wouldn't be just as unreliable.

Add test that checks all resources that can run getAsyncId(). Would like
a way to enforce that any new classes that can also run getAsyncId() are
tested, but don't have one.

c0e6c668e6 src: no abort from getter if object isn't wrapped
v8::Object::GetAlignedPointerFromInternalField() returns a random value
if Wrap() hasn't been run on the object handle. Causing v8 to abort if
certain getters are accessed. It's possible to access these getters and
functions during class construction through the AsyncWrap init()
callback, and also possible in a subset of those scenarios while running
the persistent handle visitor.

Mitigate this issue by manually setting the internal aligned pointer
field to nullptr in the BaseObject constructor and add necessary logic
to return appropriate values when nullptr is encountered.
