a555be2e45b283 re-assigned `async_.data` to indicate success
or failure of the constructor. As the `HandleWrap` implementation
uses that field to access the `HandleWrap` instance from the
libuv handle, this introduced two issues:
- It implicitly assumed that casting
`MessagePort*` → `void*` → `HandleWrap*` would be valid.
- It made the `HandleWrap::OnClose()` function fail with a
`nullptr` dereference if the constructor did fail.
In particular, the second issue made
test/parallel/test-worker-cleanexit-with-moduleload.js` crash at
least once in CI.
Since re-assigning `async_.data` isn’t actually necessary here
(only a leftover from earlier versions of that commit), fix this by
using a local variable instead, and add a `CHECK` that provides better
error messages for this type of issue in the future.

This allows keeping `BaseObjectPtr`s to `HandleWrap` instances.
Previously, the pointer kept the `HandleWrap` object alive, leaving
the Environment cleanup code that waits for the handle list to drain
in a busy loop, because only the `HandleWrap` destructor removed
the item from the list.

Referring to `BaseObject` instances using standard C++ smart pointers
can interfere with BaseObject’s own cleanup mechanisms
(explicit delete, delete-on-GC and delete-on-cleanup).
Introducing custom smart pointers allows referring to `BaseObject`s
safely while keeping those mechanisms intact.

Previously, handles would not be closed when the current `Environment`
stopped, which is acceptable in a single-`Environment`-per-process
situation, but would otherwise create memory and file descriptor
leaks.
Also, introduce a generic way to close handles via the
`Environment::CloseHandle()` function, which automatically keeps
track of whether a close callback has been called yet or not.

- 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.

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 reverts commit 9bb5a5e2a127010807f5b8a8bf4cf34109271c55.
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.
API comparison:
IsRefed -> Has a strong reference AND is alive. (Deterministic)
Unrefed -> Has a weak reference OR is dead. (Less deterministic)

This fixes my perceived usability issues with 7d8882b. Which, at the
time of writing, has not landed in any release except v6 RCs. This
should not be considered a breaking change due to that.
It is useful if you have a handle, even if it has been closed, to be
able to inspect whether that handle was unrefed or not. As such, this
renames the method accordingly. If people need to check a handle's
aliveness, that is a separate API we should consider exposing.

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.

Fixes a 4 byte leak on handles closing. AKA The Walmart leak.
MakeCallback doesn't have a HandleScope. That means the callers scope
will retain ownership of created handles from MakeCallback and related.
There is by default a wrapping HandleScope before uv_run, if the caller
doesn't have a HandleScope on the stack the global will take ownership
which won't be reaped until the uv loop exits.
If a uv callback is fired, and there is no enclosing HandleScope in the
cb, you will appear to leak 4-bytes for every invocation. Take heed.

AsyncListener is a JS API that works in tandem with the AsyncWrap class
to allow the user to be alerted to key events in the life cycle of an
asynchronous event. The AsyncWrap class has its own MakeCallback
implementation that core will be migrated to use, and uses state sharing
techniques to allow quicker communication between JS and C++ whether the
async event callbacks need to be called.
