== [mediaqueries] Change dci-p3 back to p3 ==
The commit b7e9438393033fad1e390f41a4558cb735b3507c changed the p3 
value in the color-gamut media query to dci-p3. I suggest that should 
be reverted.

1. Unlike the color() function, the identifier here is supposed to be 
intentionally vague. "P3" refers to a set of similar profiles, so 
there is no point singling one out in particular. What's the point of 
saying "DCI P3" if the display supports "Adobe RGB", which is 
considered close enough to return true?

2. "DCI P3" isn't much more accurate than just "P3" anyway. My version
 of Photoshop supports 7 different profiles with "P3" in the name, 6 
of which have "DCI P3" in the name. And funnily enough, it's the odd 
one out, "Display P3", that you probably want to use on current Apple 
hardware. I didn't suggest "display-p3" when proposing this feature 😄 

3. [Clearly not a strong reason!] WebKit has already implemented and 
promoted "p3". There is a small window of opportunity to change this 
before iOS 10/Sierra, and I'm willing to do so, but I will have to 
wonder whether it is worth keeping "p3" around 😦
