This also changes the Library window to use the newly added back-end object. The only user-visible change should be how the selection behaves when retrying downloads.

The DownloadList object now provides batch notifications directly, in preparation for linking front-end views to other types of download lists without having to use the DownloadsData indirection.

The front-end download views now maintain the old download state themselves, instead of relying on the DownloadsData object dispatching the onDownloadStateChanged notification.
This allows each view to keep only the state relevant to it, for example the Downloads Panel already keeps the state only for the visible items. This also makes it possible for each view to use a different hash than the one provided by the legacy stateOfDownload method, and allows bypassing the DownloadsData indirection entirely.

When a new front-end view is added to the DownloadsData object, the Download objects it contains are loaded into the view starting with the newest, which is the opposite of the order used by the underlying DownloadList.
This was originally implemented as an optimization for the Downloads Panel, at a time when the full list of completed downloads was persisted in the same SQLite database as session downloads. This difference is now unnecessary given the low number of session downloads, and can be removed in preparation for bypassing the DownloadsData indirection entirely.

Changes to Promise tests designed to test .then(null) have been reverted, and the browser/extensions directory was excluded because the projects it contains have a separate process for accepting changes.

See also pt. 4. We are moving app menu notification state
into a jsm since it is not specific to one window and this
simplifies work for the new app update UI.

This removes the arrowStyledIndicator killswitch and the associated ability for system add-ons to restore the previous design of the Downloads Indicator in the toolbar. The removal includes all the related code, styles, and strings. Based on the original patch by :rexboy.

With this change two new attention states are introduced, "severe" and "warning",
along with the previous "success" and "no attention" states. "No attention" is
still a falsy value in order to mitigate any add-on compatibility issues.
"severe" and "warning states" now display an icon badge to the downloads button
(or the hamburger button if the downloads button is tucked away).

In a following patch, all DevTools moz.build files will use DevToolsModules to
install JS modules at a path that corresponds directly to their source tree
location. Here we rewrite all require and import calls to match the new
location that these files are installed to.
