2018-12-16tools: enable no-useless-constructor lint rulecjihrig
This commit enables ESLint's no-useless-constructor rule. Note that the documentation examples that only include constructor calls were left in tact.

2018-12-05lib: remove `inherits()` usageRuben Bridgewater
This switches all `util.inherits()` calls to use `Object.setPrototypeOf()` instead. In fact, `util.inherits()` is mainly a small wrapper around exactly this function while adding the `_super` property on the object as well.

2018-04-03perf_hooks: simplify perf_hooksJames M Snell
Remove the `performance.getEntries()` and `performance.clear*()` variants and eliminate the accumulation of the global timeline entries. The design of this particular bit of the API is a memory leak and performance footgun. The `PerformanceObserver` API is a better approach to consuming the data in a more transient way.

2018-03-25lib: always show ERR_INVALID_ARG_TYPE received partRuben Bridgewater
This makes a effort to make sure all of these errors will actually also show the received input. On top of that it refactors a few tests for better maintainability. It will also change the returned type to always be a simple typeof instead of special handling null.

2017-08-23perf_hooks: implementation of the perf timing APIJames M Snell
An initial implementation of the Performance Timing API for Node.js. This is the same Performance Timing API implemented by modern browsers with a number of Node.js specific properties. The User Timing mark() and measure() APIs are implemented, garbage collection timing, and node startup milestone timing. ```js const { performance } = require('perf_hooks'); performance.mark('A'); setTimeout(() => { performance.mark('B'); performance.measure('A to B', 'A', 'B'); const entry = performance.getEntriesByName('A to B', 'measure')[0]; console.log(entry.duration); }, 10000); ``` The implementation is at the native layer and makes use of uv_hrtime(). This should enable *eventual* integration with things like Tracing and Inspection. The implementation is extensible and should allow us to add new performance entry types as we go (e.g. for measuring i/o perf, etc). Documentation and a test are provided.
