This patch:
- Refactors the `MemoryRetainer` API so that the impementer no longer
calls `TrackThis()` that sets the size of node on the top of the
stack, which may be hard to understand. Instead now they implements
`SelfSize()` to provide their self sizes. Also documents
the API in the header.
- Refactors `MemoryTracker` so it calls `MemoryInfoName()` and
`SelfSize()` of `MemoryRetainer` to retrieve info about them, and
separate `node_names` and `edge_names` so the edges can be properly
named with reference names and the nodes can be named with class
names. (Previously the nodes are named with reference names while the
edges are all indexed and appear as array elements).
- Adds `SET_MEMORY_INFO_NAME()`, `SET_SELF_SIZE()` and
`SET_NO_MEMORY_INFO()` convenience macros
- Fixes a few `MemoryInfo` calls in some `MemoryRetainers` to track
their references properly.
- Refactors the heapdump tests to check both node names and edge names,
distinguishing between wrapped JS nodes (without prefixes)
and embedder wrappers (prefixed with `Node / `).

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.

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 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.

The id will not be set of the passed object has no internal field count.
As the class pointer cannot be retrieved from the object.
In order to properly report the allocated size of each class, the new

The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every

as part of the entire package.
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.
