Since it allows to animate display, which is not good.

This is a regression from:

  https://hg.mozilla.org/mozilla-central/rev/6884ba750aa3

Actually I wonder if the logic shouldn't be the other way around, i.e., a
shorthand is animatable if all the longhands are, not if just one.

In any case this rolls back to the previous behavior, should we do that, it
should be another bug.

This ended up not being so small of a patch as I'd have thought, since it
propagated a bit. But most of it is mechanical. Interesting part is
NonNegativeNumberOrPercentage and the actual uses of the NonNegative stuff and
during parsing.

This looks like it'd fix a few correctness issues during interpolation for all
the types except for BorderRadius and co (which handled it manually).

I should write tests for those in a different patch.

ExtremumLength is the keyword type for css sizing properties, so we
could use cbindgen.

In Gecko, we use nsStyleCoord to store the sizing properties, and use
integer values to check the enum values, so I keep the macros in nsStyleConsts.
Even though we need to convert the enum type into integer, we still have
benefits to reduce the complexity of converting Rust into C++, and leave
the simplified mappings in C++ for better readability.

Support unprefixed min-content and max-content and treat the prefixed
version as aliases for
1. width, min-width, max-width if inline-axis is horizontal, and
2. height, min-height, max-height if inline-axis is vertical, and
3. inline-size, min-inline-size, max-inline-size, and
4. flex-basis.

Besides, update the test cases to use unprefixed max-content and
min-content.

We should let block-size/min-block-size/max-block-size accept keywords as the
initial value, just like width in vertical writing mode or height in horizontal
writing mode.

…le(), ellipse(), and inset().

Replace LengthOrPercentage with NonNegativeLengthOrPercentage on
ShapeRadius, Circle, Ellipse. And derive ToAnimatedValue for ShapeSource and
its related types, so we clamp its interpolated results into non-negative
values. (i.e. The radius of circle()/ellipse() and the border-radius of
inset().)

Note: We may get negative values when using a negative easing function, so the
clamp is necessary to avoid the incorrect result or any undefined behavior.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.

Overall it's not a very interesting patch I think.

nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.

I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.

While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
