More precisely, make them untransferable if they were created through
*our* APIs, because those do not follow the improved free callback
mechanism that V8 uses now. All other ArrayBuffers can be transferred
between threads now, the assumption being that they were created in a
clean way that follows the V8 API on this.
This addresses a TODO comment.

Since worker threads are complete Node.js environments, including the
ability to load native addons, and since those native addons can
allocate resources to be freed when objects go out of scope, and since,
upon worker thread exit, the engine does not invoke the weak callbacks
responsible for freeing resources which still have references, this
modification introduces tracking for weak references such that a list
of outstanding weak references is maintained. This list is traversed
during environment teardown. The callbacks for the remaining weak
references are called.
This change is also relevant for Node.js embedder scenarios, because in
those cases the process also outlives the `node::Environment` and
therefore weak callbacks should also be rendered as environment cleanup
hooks to ensure proper cleanup after native addons. This changes
introduces the means by which this can be accomplished.
A benchmark is included which measures the time it takes to execute the
weak reference callback for a given number of weak references.

Adds `napi_set_instance_data()` and `napi_get_instance_data()`, which
allow native addons to store their data on and retrieve their data from
`napi_env`. `napi_set_instance_data()` accepts a finalizer which is
called when the `node::Environment()` is destroyed.
This entails rendering the `napi_env` local to each add-on.

Its intended that *-inl.h header files are only included into the src
files that call the inline methods. Explicitly include it into the files
that need it.

Crashes were reported during finalization due to
the memory for a reference being deleted and the
finalizer running after the deletion.
This change ensures the deletion of the memory for
the reference only occurs after the finalizer has run.

Split the Node.js ECMAScript API (N-EAPI?) into its own header and
implementation files. The motivation is that the ECMAScript API stand
on its own so it might be embedded separately, implementation and all.
Portions of the implementation used by both files are stored in
`node_api_impl.h`.
The checked boxes below indicate that the given API remains in
`node_api.h`, whereas the lack of a checkbox indicates that the API was
moved to `node_ecma_api.h`.
