Support ChaCha20-Poly1305 and Camellia-GCM for debian and ubuntu openssl package

In order to easily build, I made sets of patches that resolved conflicts (chacha20-poly1305, camellia-gcm, equal-preference-group).

How to build

Required packages: packaging-dev, lzip / Preparation: sudo apt-get build-dep openssl or openssl1.0

Adds a timeout to a JavaScript promise, rejects if not resolved within timeout period (uses requestAnimationFrame for better accuracy)

	(function () {

	'use strict';

	/**
	* wraps a promise in a timeout, allowing the promise to reject if not resolve with a specific period of time
	* @param {integer} ms - milliseconds to wait before rejecting promise if not resolved
	* @param {Promise} promise to monitor
	* @example
	* promiseTimeout(1000, fetch('https://courseof.life/johndoherty.json'))
