2019-11-25lib: flatten access to primordialsMichaël Zasso
Store all primordials as properties of the primordials object. Static functions are prefixed by the constructor's name and prototype methods are prefixed by the constructor's name followed by "Prototype". For example: primordials.Object.keys becomes primordials.ObjectKeys.

2019-02-21process: simplify the setup of async hooks trace eventsJoyee Cheung
- Remove `trace_category_state` from `Environment` - since this is only accessed in the bootstrap process and later in the trace category update handler, we could just pass the initial values into JS land via the trace_events binding, and pass the dynamic values directly to the handler later, instead of accessing them out-of-band via the AliasedBuffer. - Instead of creating the hooks directly in `trace_events_async_hooks.js`, export the hook factory and create the hooks in trace category state toggle.

2019-02-02lib: save primordials during bootstrap and use it in builtinsJoyee Cheung
This patches changes the `safe_globals` internal module into a script that gets run during bootstrap and saves JavaScript builtins (primordials) into an object that is available for all other builtin modules to access lexically later.

2018-03-09src: add tracing category macrosJames M Snell
Adds `TRACING_CATEGORY_NODE`, `TRACING_CATEGORY_NODE1` and `TRACING_CATEGORY_NODE2` helper macros for consistently building trace event category strings. For instance, `TRACING_CATEGORY_NODE2(foo, bar)` would generate the category string `node,node.foo,node.foo.bar`, such that... ``` TRACE_EVENT_NESTABLE_ASYNC_BEGIN0( TRACING_CATEGORY_NODE2(foo, bar), "baz", 1); ``` Would emit if trace events are enabled for categories: `node`, `node.foo`, or `node.foo.bar`. This allows a natural scoping down of what trace events a user may want to receive. Enabling the `node` category would receive everything Node.js produces.

In theory this could be inferred from the before and after events but this is much simpler and doesn't require knowledge of all events.
