L. David Baron 80f5a01d0c Bug 1058346 patch 2 - Add eRestyle_SVGAttrAnimations and support it in nsStyleSet::RuleNodeWithReplacement. r=birtles
This allows posting a restyle that says that only the rule(s) from the
SVGAttrAnimationSheet cascade level will be replaced, which avoids running
selector matching.

This is needed to land bug 977991 prior to landing bug 960465, since
that requires replacing all levels that contain animations.

(I'll rename this to match the name determined in bug 1057231.)
