589b2a1244 perf_hooks: add idleTime and event loop util 
Use uv_metrics_idle_time() to return a high resolution millisecond timer
of the amount of time the event loop has been idle since it was
initialized.

Include performance.eventLoopUtilization() API to handle the math of
calculating the idle and active times. This has been added to prevent
accidental miscalculations of the event loop utilization. Such as not
taking into consideration offsetting nodeTiming.loopStart or timing
differences when being called from a Worker thread.

2020-04-14, Version 13.13.0 (Current) 
Notable changes:

New file system APIs:
* Added a new function, `fs.readv` (with sync and promisified versions).
  This function takes an array of `ArrayBufferView` elements and will
  write the data it reads sequentially to the buffers
  (Sk Sajidul Kadir). https://github.com/nodejs/node/pull/32356
* A new overload is available for `fs.readSync`, which allows to
  optionally pass any of the `offset`, `length` and `position`
  parameters. https://github.com/nodejs/node/pull/32460

Other changes:
* dns:
  * Added the `dns.ALL` flag, that can be passed to `dns.lookup()` with
    `dns.V4MAPPED` to return resolved IPv6 addresses as well as IPv4
    mapped IPv6 addresses (murgatroid99).
    https://github.com/nodejs/node/pull/32183
* http:
  * The default maximum HTTP header size was changed from 8KB to 16KB
    (rosaxny). https://github.com/nodejs/node/pull/32520
* n-api:
  * Calls to `napi_call_threadsafe_function` from the main thread can
    now return the `napi_would_deadlock` status in certain
    circumstances (Gabriel Schulhof).
    https://github.com/nodejs/node/pull/32689
* util:
  * Added a new `maxStrLength` option to `util.inspect`, to control the
    maximum length of printed strings. Its default value is `Infinity`
    (rosaxny). https://github.com/nodejs/node/pull/32392
* worker:
  * Added support for passing a `transferList` along with `workerData`
    to the `Worker` constructor (Juan José Arboleda).
    https://github.com/nodejs/node/pull/32278

New core collaborators:
With this release, we welcome three new Node.js core collaborators:
* himself65. https://github.com/nodejs/node/pull/32734
* flarna (Gerhard Stoebich). https://github.com/nodejs/node/pull/32620

2ec6995555 perf_hooks: simplify perf_hooks 
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.

67269fd7f3 perf_hooks: implementation of the perf timing API 
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.
