Xpra: Ticket #1788: 2.4 html5 updates

Follow up from #1670.

The changelog: log/xpra/trunk/src/html5

Lots of goodies in the latest chrome builds: Chrome 66 Beta: CSS Typed Object Model, Async Clipboard API, AudioWorklet:

ImageBitmapRenderingContext: This new rendering context uses transfer semantics to take ownership of the pixels of an ImageBitmap? object, thus avoiding memory duplication and rasterization overhead.

(from The ImageBitmap rendering context for canvas) - not sure about zerocopy since this populates a canvas but worth a look

Unblocking Clipboard Access: The new asynchronous clipboard API provides a promise-based means of reading from and writing to the clipboard. and As with many new APIs, navigator.clipboard is only supported for pages served over HTTPS. To help prevent abuse, clipboard access is only allowed when a page is the active tab. Pages in active tabs can write to the clipboard without requesting permission, but reading from the clipboard always requires permission.
AudioWorklet: The AudioWorklet? object provides a new synchronous JavaScript? execution context which allows developers to programmatically control audio without additional latency and higher stability in the output audio. - looks like exactly what we need (see #1775)
