* `LonghandId` and `ShorthandId` are C-like enums
* `Atom` is used for the name of custom properties.
* `PropertyDeclarationId` is the identifier for `PropertyDeclaration`,
after parsing and shorthand expansion. (Longhand or custom property.)
* `PropertyId` represents any CSS property, e.g. in CSSOM.
(Longhand, shorthand, or custom.)
Using these instead of strings avoids some memory allocations and copies.
Write tests for CSSOM Interfaces
<!-- Please describe your changes on the following line: -->
ToCss implementation was wrong about Keyframe percentage values, it was writing values between 0-1. I had to fix it. Wrote some tests about CSSKeyframesRule, CSSNamespaceRule, CSSRuleList, CSSStyleSheet, StyleSheetList interfaces.
CSSFontFaceRule and CSSViewportRule looks like not implemented yet. I didn't write one for them.
Also name attribute in CSSKeyframesRule isn't implemented yet. Is there any complication about it? If not, I can implement it.

allow the style bloom filter to recover from switch to a node with no common ancestor with the old node
<!-- Please describe your changes on the following line: -->
Since https://bugzilla.mozilla.org/show_bug.cgi?id=1321284, we can have multiple disjoint subtrees of elements to style in a document, due to document level native anonymous content not inheriting from the document's element. This patch tweaks the style Bloom filter to allow switching to a new node that has no common ancestor with the old node.

Treat top-level number in calc() invalid
<!-- Please describe your changes on the following line: -->
This should probably considered as a temporary fix (for [bug 1321206](https://bugzilla.mozilla.org/show_bug.cgi?id=1321206)), to avoid assertion when trying to serialize calc value with only numbers. Certain properties (e.g. `line-height`) would eventually need to keep numbers inside calc.

Currently, CalcLengthOrPercentage doesn't actually keep the number value. If we don't treat it invalid, we can end up generating empty `calc()` value when one contains numbers (e.g. `calc(1)`), which would violate assertion elsewhere that `calc` must not be empty.

Currently, CalcLengthOrPercentage doesn't actually keep the number
value, so if we don't treat it invalid, we can end up generating empty
`calc()` value when one contains top-level numbers (e.g. `calc(1)`),
which would violate assertion elsewhere that `calc` must not be empty.
This is not a problem for Servo, because we recovered it without much problem a
few lines below, and we never reached the pathological case where the filter has
one element (the root), and we restyled another element with depth 1.
Fixes bug 1321725.

transition is the same as the end value for a running transition per
CSS-TRANSITIONS § 3.
Besides being contrary to spec, the old behavior could cause a cascade
of CSS transitions incorrectly triggering themselves when calls to
`getComputedStyle()` were intermingled with them.
Improves performance of nytimes.com.
