This update covers 1575 commits, including 144 new upstream commits I've never filed a bug on before. (They're the top 144.):

1575 commits elided, as they are too long for a bugzilla comment.

I've submitted a try run for this commit: https://treeherder.mozilla.org/jobs?repo=try&revision=4c25b0c08605b9064bb3247b6fbf158583b2757c

All the jobs in the try run succeeded. Like literally all of them, there weren't
even any intermittents. That is pretty surprising to me, so maybe you should double
check to make sure I didn't misinterpret things and that the correct tests ran...

Anyway, I've done all I can, so I'm passing to you to review and land the patch.
When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.

The following patch is waiting for review from a reviewer who resigned from the review:

:update-bot, could you please find another reviewer?
