Deduplicating code is nice, and it will help us when we make the bit
propagation more complicated in upcoming patches.

Using namespace id fixes this issue because in Gecko, the pref of MathML
(as well as SVG) works in the way that we choose a different namespace
id (the disabled id) for the elements. Those ids are mapped to the same
namespace atom as normal ids, which means if we use the atom, we would
treat the elements like normal mathml elements.
Rework MediaType to be an atom-based struct instead of an enum.

The check isn't doing what the comment is saying.
XBL subtrees for video controls all have the
NODE_IS_IN_NATIVE_ANONYMOUS_SUBTREE flag, but not all of them are NAC
themselves, so we may incorrectly miss blockification.

stylo: Bug 1374233 - Clamp interpolated values for properties which need to be restricted
Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.

Add NonNegativeLength, which could be computed to NonNegativeAu. So we
can declare Either<NonNegativeLength, X>, X=Auto, Normal, or Number.
NonNegativeLengthOrAuto is for column-width.
NonNegativeLengthOrNormal is for column-gap.
NonNegativeLengthOrNumber is for -moz-tab-size.

style: Move nsStyleContext::mParent to GeckoStyleContext.
Unfortunately this means that we lose the NS_STYLE_INHERIT_BIT optimization to
avoid posting changes if we had not requested the struct. In practice, I'm not
sure this optimization matters much, though, and we already compare all the
structs anyway.
We _could_ keep a weak parent pointer from the text style if needed, given we're
going to keep alive the text style at least until the parent style context goes
away, so should be safe, but I don't think the extra churn is worth it, to be
honest. Happy to do so as part of bug 1368290 if you think it's worth it.

The motivation is that Chrome XBL stylesheets can be parsed under author
level, but we allow some event-state pseudo classes like
:-moz-handled-clicktoplay to be used.
Also synchronize the privilege of pseudo classes in
non_ts_pseudo_class_list.rs and nsCSSPseudoClassList.h (except :fullscreen).
