Bug 181172 – Identify MessagePorts by a globally unique MessagePortIdentifier

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Brady Eidson]

Identify MessagePorts by a globally unique MessagePortIdentifier

"Globally unique" in this context means that no matter which process a MessagePort is originally created in, its identifier is guaranteed to not conflict with a port created in any other process. See https://bugs.webkit.org/show_bug.cgi?id=181155 for the precursor to this.

This is the final refactor necessary before WK2 multi-process MessagePorts.

Could this use Darin's new computeHash?  See https://bugs.webkit.org/show_bug.cgi?id=180318
