1539270 - Have XPConnect instantiate a JS Helperthread pool using XPCOM threadpools

Status: RESOLVED FIXED

(Core :: XPConnect, enhancement, P2)

Description

[Kris Wright :KrisWright]

In order to bring HelperThreads over into the XPCOM thread pools, we need to instantiate an nsThreadPool instance in xpconnect to dispatch tasks to. It needs to take a common task type from JS (see Bug 1532803) managed by some subclass of mozilla::Runnable that can define its own run() method for dispatch.

Added HelperThreadPool & HelperThreadTaskHandler classes to hold and manage an nsThreadPool. Initialized thread pool in XPCJSRuntime and created the HelperThreads() method to access directly.

Created a hook in Runtime to expose the helper thread dispatch method to js, which is set by XPCJSRUntime::init.
