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.

Creating non-shared scopes for frame scripts is fairly expensive. After these
changes it's even more expensive. However, many frame scripts have no use for
the shared scopes at all. Run-once scripts which execute in closures, for
instance, make no use of them. And after bug 1472491, neither do most of our
default frame scripts.

Regression from bug 1398713. Before that, we reloaded the entire webext-panel.xul if the
sidebar changed. This verifies we don't reload unecessarily as well as discards
the browser to force a runtime disconnect for the extension if it does change.

Also removes some dead code.
A lot of the code in ExtensionUtils.jsm is not needed in all processes, and a
lot of the rest isn't needed until extension code runs. Most of it winds up
being loaded into all processes way earlier than necessary.
