[css3-images][css4-images] Replace 'dppx' with 'x'?

There's been a decent bit of feedback recently about the 'dppx'
resolution unit, since Responsive Images have become popular over in
HTML.  The feedback has pretty much all been negative about the name,
though.  It seems to be generally considered to be a difficult name to
read and even write (with a lot of 'ddpx' typos, even from people here
in the WG).

Apple's image-set() proposal, and HTML's new <img srcset> proposal,
both use a simple 'x' unit to denote the same thing.  What do we think
about doing the same thing?

I see two ways this could happen:

1. We modify the Images 3 CR.  In the absence of a CR errata
mechanism, this means another Last Call, though we could certainly
annotate the draft to make it clear that it's not a big deal, or
simply keep it low-key like we did with B&B recently.

2. We wait for Images 4 and add it, deprecating dppx along the way.
We can either invoke an explicit aliasing mechanism here, or just
define it identically and say that authors must not use dppx.
