Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

This makes it possible to subscribe to DOM events in web content, in
order to facilitate fixes for cases such as https://bugzil.la/1397007.
Although the current interface, WebElementEventTarget, is associated with
browser.Context (curBrowser) it is the intention that we in the future
will associate this with representations of the marshaled web element.
This will make it quack and act like an Element's EventTarget, which
has nice parity to it.
The WebElementEventTarget works by passing IPC messages to
a backend service in the content frame script implemented by
ContentEventObserverService. This registers event handlers for specific
DOM events, and relays these events back to the browser-specific message
handler in chrome.
This will enable chrome code to wait for events to occur in content,
like this:
await new Promise(resolve => {
webElement.addEventListener("visibilitychange", resolve, {once: true});
contentBrowser.minimize();
});
