Add a utility functions for addons to use when they need
a reference to the current event loop.
While the libuv API is not directly part of N-API, it
provides a quite stable C API as well, and is tightly
integrated with Node itself.
As a particular use case, without access to the event loop
it is hard to do something interesting from inside a N-API
finalizer function, since calls into JS and therefore virtually
all other N-API functions are not allowed.

The binding testing napi_wrap() creates references to primitives passed
into the binding in its second parameter. This is unnecessary and not
at all the point of the test. Additionally, creating persistent
references to primitive values may not be supported by all VMs, since
primitives are best persisted in their native form.
Instead, the point of the test is to make sure that the finalize
callback gets called when it should get called, that it gets called
with the correct pointer, and that it does not get called when it
should not get called. Creating persistent references is not necessary
for verifying this.

Currently the nm_modname does not match the file name of the resulting
module. In fact, the nm_modname is pretty arbitrary. This seeks to
introduce some consistency into the nm_modname property by having the

property of the gyp target that builds the module.

Promise is implemented as a pair of objects. `napi_create_promise()`
returns both a JavaScript promise and a newly allocated "deferred" in
its out-params. The deferred is linked to the promise such that the
deferred can be passed to `napi_resolve_deferred()` or
`napi_reject_deferred()` to reject/resolve the promise.
`napi_is_promise()` can be used to check if a `napi_value` is a native
promise - that is, a promise created by the underlying engine, rather
than a pure JS implementation of a promise.

Calling napi_wrap() twice on the same object has the result of returning
napi_invalid_arg on the second call. However, sometimes it is necessary
to replace the native pointer associated with a given object. This new
API allows one to remove an existing pointer, returning the object to
its pristine, non-wrapped state.

- Add separate APIs for creating different kinds of numbers,
because creating a V8 number value from an integer is faster
than creating one from a double.
- When getting number values, avoid getting the current context
because the context will not actually be used and is expensive
to obtain.
- When creating values, don't use v8::TryCatch (NAPI_PREAMBLE),
because these functions have no possibility of executing JS code.

Use a stronger criterion to identify objects in the prototype chain that store
pointers to native data that were added by previous calls to `napi_wrap()`.
Whereas the old criterion for identifying `napi_wrap()`-injected prototype
chain objects was to consider an object with an internal field
count of 1 to be such an object, the new criterion is to consider an object
with an internal field count of 2 such that the second field holds a
`v8::External` which itself contains a pointer to a global static string unique
to N-API to be a `napi_wrap()`-injected prototype chain object.
This greatly reduces the possibility of returning a pointer that was not
previously added with `napi_wrap()`, and it allows us to recognize that an
object has already undergone `napi_wrap()` and we can thus prevent a chain of
wrappers only the first of which is accessible from appearing in the prototype
chain, as would be the result of multiple calls to `napi_wrap()` using the same
object.
