Shane Hughes 1eae42ffc3 Bug 1755570 - Add download deleted state to UI. r=Gijs
Add a new property to downloads such that downloaded files deleted from within
Firefox (currently just by the context menu item) are marked "File deleted"
instead of "File moved or missing" (this adds a new translation). Also refactor
downloadsCmd_deleteFile and downloadsCmd_cancel to clean up some related issues.
Add a new download history metadata property so that Firefox can persist this
"File deleted" state between sessions.

This should resolve bug 1755570 as well as bug 1755728. Bug 1755729 is a
separate issue, more like an enhancement, because missing/moved downloads have
never allowed resume/retry. They couldn't be resumed as they were stopped, not
paused. They could conceivably be retried but this would be adding a whole lot
of new core download logic, since the target and saver are in a very different
state for a stopped download with a deleted file than what they'd be if the
download was merely canceled.

So, this patch won't give the user an opportunity to resume/retry deleted
downloads. Previously we had a problem where we made it look like you could
retry a download if you used the "delete file" command while the download was in
progress. This patch will make sure that using the "delete file" command
actually finalizes the download. So it will just fix the immediate problem where
some menuitems and buttons simply don't work in edge cases. A later patch can
implement a new affordance that will allow "retrying" downloads that were
already downloaded/interrupted and deleted, whether from within Firefox or not.
