FromJust() is often used not for its return value, but for its

the intent. From its comment:
To be used, where the actual value of the Maybe is not needed, like
Object::Set.

Since libuv 1.21.0, pipes on Windows support `writev` on the

This allows for some simplification, and makes the `StreamBase`

- 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
ddc19be6de1ba263d9c175b2760696e7b9918b25) 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 ddc19be6de1ba263d9c175b2760696e7b9918b25, I do not
think that this is going to have any impact on diagnostic tooling.

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.

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.

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.

This API is not suitable because it depended on being able to
potentially access the handle's flag after the handle was already
cleaned up. Since this is not actually possible (obviously, oops)
this newer API no longer makes much sense, and the older API is more
suitable.

IsRefed -> Has a strong reference AND is alive. (Deterministic)
Unrefed -> Has a weak reference OR is dead. (Less deterministic)

It is useful if you have a handle, even if it has been closed, to be

aliveness, that is a separate API we should consider exposing.

Notably, this should be helpful for inspection via AsyncWrap.
Also, this is useful even to node's internals, particularly timers.
