Feature freezes and Emacs 25 (was: Dynamic loading progress)

[John Wiegley]

Since Emacs 25 is not yet released, the transfer of maintainership comes at a
slightly awkward time. I haven't fully caught my breath yet, but don't want to
impede Stefan's legacy from getting out the door.

Let us officially freeze in one weeks, next Friday, Nov 13 at 11:59 PM UTC, so
that any ready, last minute features can get in before 25.1 is closed. Then
we'll take a pause and review whether anything should be allowed after the
freeze. Once we're comfortable with the bug situation, we release.

I'd like to take a somewhat generous period for bug fixes, with feature work
happening in the meanwhile on topic branches. All severe bugs should either be
closed, or consciously deferred, before letting 25 out the door.
