legendecas 71ff89f929 src: rename internal module declaration as internal bindings 
This is a continuation of the name reification on the internal bindings.

Renames NODE_MODULE_CONTEXT_AWARE_INTERNAL and
NODE_MODULE_EXTERNAL_REFERENCE to NODE_BINDING_CONTEXT_AWARE_INTERNAL
and NODE_BINDING_EXTERNAL_REFERENCE respectively.

Joyee Cheung 6ef4368db4 src: track contexts in the Environment instead of AsyncHooks 
This makes it easier to support the vm contexts in the startup
snapshot. We now manage the promise hooks using references to
the contexts from the Environment, and AsyncHooks only hold references
to the hooks.

Joyee Cheung 5b1bcf82f1 vm: make ContextifyContext a BaseObject 
Instead of adding a reference to the ContextifyContext by using
a v8::External, we make ContextifyContext a weak BaseObject that
whose wrapper is referenced by the sandbox via a private symbol.
This makes it easier to snapshot the contexts, in addition to
reusing the BaseObject lifetime management for ContextifyContexts.

Joyee Cheung 7900f6540e vm: avoid unnecessary property getter interceptor calls 
Access to the global object from within a vm context is intercepted
so it's slow, therefore we should try to avoid unnecessary access
to it during the initialization of vm contexts.

- Remove the Atomics.wake deletion as V8 now does not install it
  anymore.
- Move the Intl.v8BreakIterator deletion into the snapshot.
- Do not query the Object prototype if --disable-proto is not set.

This should speed up the creation of vm contexts by about ~12%.

Joyee Cheung cfd25e0c74 vm: make ContextifyContext template context-independent 
Instead of creating an object template for every ContextifyContext,
we now create one object template that can be reused by all
contexts. The native pointer can be obtained through an embdder
pointer field in the creation context of the receiver in the
interceptors, because the interceptors are only meant to be invoked
on the global object of the contextified contexts. This makes
the ContextifyContext template context-independent and therefore
snapshotable.

Some embedders, like Electron, choose to start Node.js with
`only_terminate_in_safe_scope` set to `true`. In those cases, parts
of the API that expect execution termination to happen need to
be marked as able to receive those events. In our case, this is
the Ctrl+C support of the `vm` module (and Workers, but since
we’re in control of creating the `Isolate` for them, that’s a
non-concern there).

Add those scopes and add a regression test.

Joyee Cheung 5f2c4ce74f vm: fix vm.measureMemory() and introduce execution option 
https://github.com/nodejs/node-v8/pull/147 broke the
`vm.measureMemory()` API. It only created a `MeasureMemoryDelegate` and
without actually calling `v8::Isolate::MeasureMemory()` so the returned
promise will never resolve. This was not caught by the tests because
the promise resolvers were not wrapped with `common.mustCall()`.

This patch migrates the API properly and also introduce the newly
added execution option to the API. It also removes support for
specifying contexts to measure - instead we'll just return the
measurements for all contexts in the detailed mode, which is
what the `performance.measureMemory()` prototype in V8 currently does.
We can consider implementing our own `v8::MeasureMemoryDelegate`
to select the target context in `ShouldMeasure()` in the future,
but then we'll also need to implement `MeasurementComplete()`
to assemble the result. For now it's probably too early to do that.

Since this API is still experimental (and guarded with a warning),
such breakage should be acceptable.

Joyee Cheung a33c3c6d33 src: refactor uncaught exception handling 
The C++ land `node::FatalException()` is not in fact fatal anymore.
It gives the user a chance to handle the uncaught exception
globally by listening to the `uncaughtException` event. This patch
renames it to `TriggerUncaughtException` in C++ to avoid the confusion.

In addition rename the JS land handler to `onGlobalUncaughtException`
to reflect its purpose - we have to keep the alias
`process._fatalException` and use that for now since it has been
monkey-patchable in the user land.

This patch also

- Adds more comments to the global uncaught exception handling routine
- Puts a few other C++ error handling functions into the `errors`
  namespace
- Moves error-handling-related bindings to the `errors` binding.

Sam Roberts 060d901f87 src: replace FromJust() with Check() when possible 
FromJust() is often used not for its return value, but for its
side-effects. In these cases, Check() exists, and is more clear as to
the intent. From its comment:

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