We had a mix of 0.6.2 and 0.6.5 (which is the current release),
this unifies to the latest version. It also enables the union
feature which removes the discriminant, reducing memory usage.

This cherry-picks servo/servo#21746.

Bug 1484285 - Avoid loading XBL bindings for stuff that is very likely to be a custom-element. r=smaug

This should be more generic than hardcoding the tags, and be enough for our
chrome to avoid regressions as they migrate more stuff to CE, avoiding calling
into the GetComputedStyle machinery..

Backed out changeset d432e26bd0b5 (bug 1419091) for mochitest failures on dom/tests/mochitest/keyhandling/test_input.html.

Summary:
This method isn't specific to tabs. It can attach to any "target" actor that inherits from BrowsingContextActor.

Summary:
Now that all the "remoting" of this method has been moved to TargetFactory.createTargetForTab,
we should rename this method to what it does now. It mostly call attach requests
of the target actor and its child console actor.
It also "connect" the webextension target actor, but I would like to eventually move that
outside of TabTarget.attach, like makeRemote.

Summary:
When switching to async, it is important to catch exception or register a rejection handler
so that errors keep being logged.
So in this patch I'm catching exception in a couple of important codepath.

MozReview-Commit-ID: 2fTZ4WRq9je

Summary:
Fetching any target is now asynchronous. But RDM setup/destroy codepath is very fragile
and introduce many low level exception when trying to restore the original browser element
if any timing changes.
So this patch prevents trying to fetch the target object if a toolbox isn't already opened.
The target object is being used only for Telemetry purpose for now.
