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.

Normalize errors thrown by extension API implementations in content
processes to ensure that extension code can read the error message
if the error is an instance of ExtensionUtils.ExtensionError.
This code path is triggered in browser_ext_menus_replace.js and
browser_ext_menus_replace_menu_permissions.js.

- Register pagehide/pageshow events in the system group and ignore
synthetic events to avoid interference from web pages.
- Remove unused docShell member.
- Fix memory leak in bfcached windows, by ensuring that BaseContext
instances can be GC'd when an extension is unloaded, even if the
context is associated with a page in the bfcache.
- Ensure that context.contentWindow and context.active always have an
accurate value.
The latter is achieved by moving all contentWindow tracking logic in a
new helper class "InnerWindowReference".

I generally tried to preserve the behavior of consumers where they treated an
exception from getInterface(Ci.nsIContentFrameMessageManager) as a signal to use
some sort of fallback.
I did change the behavior of consumers that walked up to the root same-type
docshell before getting the message manager to just get it directly from the
docshell they have. Please review those parts carefully, and let me know if you
want me to ask some subject area experts to review those.

DocShells are associated with outer DOM Windows, rather than Documents, so
having the getter on the document is a bit odd to begin with. But it's also
considerably less convenient, since most of the times when we want a docShell
from JS, we're dealing most directly with a window, and have to detour through
the document to get it.

When a background page has a messaging listener but the background page
is started in response to something other than an extension message, we
were missing the background "startup" event. Fix that by setting up the
listener earlier.

- Un-lazify the startup promises in ext-toolkit.js since the
manifest background property is handled asynchronously, so it
races with startup and can miss the relevant events if it
loses the race.
- Ensure that persistent events don't cause breakage when the
background-delayed-startup preference is set to false.
- Add a wakeup() method to the fire object provided to primed
listeners. This method returns a Promise that resolves when
the extension background page has started. Events that need to
do some work in the context of the extension can wait on the
result of wakeup(), then continue processing after the background
page is started, using fire.[a?]sync as normal.

These issues were previously ignored due to the nature of our global import
rules. They need to be fixed before that rule can be updated.

As we add more behaviors to EventManager, the signature of the constructor
is going to get really clumsy. Head that off by converting it to take a
general parameters object.
This introduces a compatibility problem for existing webextension experiments,
put in a backward-compatibility shim for now.

Currently, when we create an error object at the end of an aysnc operation, we
only get a useful caller location if async stacks are enabled.
This patch changes our behavior to use the saved caller location we've already
stored when creating an Error object based on a plain string message.

When we report errors generated by async API operations, they are currently
not tied to any relevant extension source location. Instead, the locations in
the error reports point to the location in the framework code which reported
the error, which makes things extremely difficult to diagnose.
This change saves the extension caller location at the beginning of async API
operations, and adds it to the error reports genearted by that operation. This
should give extension developers a useful starting point for debugging them.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
