The Demise of 2.4.1-devel

[Richard Kimberly Heck]

I've merged 2.4.1-devel into 2.4.x, so it should no longer be used. 
Commits to stable should now all go to 2.4.x.

I'm intending to release 2.4.1 around 1 July. We already have 23 bugs 
fixed. If you're feeling like fixing some others, there's a list of open 
bugs for 2.4.1 and 2.4.x here:

It would be particularly good if we could fix #13069, since that's a crash.
