Bug 1310771 - Part 2: Emit BrowserWillChangeProcess and BrowserChangedProcess when doing cross-frameloader navigations, r=smaug With GroupedSHistory, history navigations may now require the browser to change which frameloader is stored internally from within Core. This patch adds a mechanism to allow for chrome code to respond to these changes and both delay the change, or respond once the change is performed. Delaying the change is accomplished through the BrowserWillChangeProcess event, which is fired when it is determined that a process change will happen for the given browser, but the change has not occured yet. During this time the nsIFrameLoader::AddProcessChangeBlockingPromise method may be called on the target browser's frameloader. Any promises passed to this method will be waited on, and the process change will not occur until they have all been fulfiled. Once that has occured, the process change occurs, and the BrowserChangedProcess event is fired. This is useful for chrome code which needs to flush state from the original process before the change, and then which needs to connect state in the new process with state in the chrome process.
