2018-10-03src: use JS inheritance for `AsyncWrap`Anna Henningsen
For all classes descending from `AsyncWrap`, use JS inheritance instead of manually adding methods to the individual classes. This allows cleanup of some code around transferring handles over IPC.

This adds the `multipleResolves` event to track promises that resolve more than once or that reject after resolving. It is important to expose this to the user to make sure the application runs as expected. Without such warnings it would be very hard to debug these situations.

2018-08-22src: refactor options parsingAnna Henningsen
This is a major refactor of our Node’s parser. See `node_options.cc` for how it is used, and `node_options-inl.h` for the bulk of its implementation. Unfortunately, the implementation has come to have some complexity, in order to meet the following goals: - Make it easy to *use* for defining or changing options. - Keep it (mostly) backwards-compatible. - No tests were harmed as part of this commit. - Be as consistent as possible. - In particular, options can now generally accept arguments through both `--foo=bar` notation and `--foo bar` notation. We were previously very inconsistent on this point. - Separate into different levels of scope, namely per-process (global), per-Isolate and per-Environment (+ debug options). - Allow programmatic accessibility in the future. - This includes a possible expansion for `--help` output. This commit also leaves a number of `TODO` comments, mostly for improving consistency even more (possibly with having to modify tests), improving embedder support, as well as removing pieces of exposed configuration variables that should never have become part of the public API but unfortunately are at this point.

2018-04-17trace_events: adds a new trace_events apiJames M Snell
Removes the requirement to use `--trace-events-enabled` to enable trace events. Tracing is enabled automatically if there are any enabled categories. Adds a new `trace_events` module with an API for enabling/disabling trace events at runtime without a command line flag. ```js const trace_events = require('trace_events'); const categories = [ 'node.perf', 'node.async_hooks' ]; const tracing = trace_events.createTracing({ categories }); tracing.enable(); // do stuff tracing.disable(); ``` Multiple `Tracing` objects may exist and be enabled at any point in time. The enabled trace event categories is the union of all enabled `Tracing` objects and the `--trace-event-categories` flag.
