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.

There was a problem hiding this comment.
@devsnek I tried a cctest on V8 master and it seems the issue still exist. However we still need to catch the error even when it's fixed since runInAsyncScope() will swallow the error.
