We have three different enums to represent slightly different things. Reuse them
properly, and kill some code in the animated_properties module while at it.

Measure PropertyDeclaration more thoroughly.
This patch replaces the handwritten MallocSizeOf implementation for
PropertyDeclaration with a derived one, which gives much more thorough
measurement.
This requires (a) deriving MallocSizeOf for a *lot* of additional types (most
of which already have `derive(HeapSizeOf)` in Servo builds), and (b)
implementing MallocSizeOf for a few more types in the `malloc_size_of` crate.
These changes would significantly improve the reporting coverage for gmail if
it weren't for the fact that SpecifiedUrl isn't measured due to a lack of
clarity about its fields; that can be fixed as a follow-up once bug 1397971 has
landed.

Make serialization match Gecko in a few corner cases
This addresses the testcases from https://bugzilla.mozilla.org/show_bug.cgi?id=1345218. Gecko differs from the specification by doing the following:
* reusing longhands that have previously been serialized in order to serialize shorthands
* immediately breaking out of the shorthand loop for the current property as soon as a shorthand is successfully serialized
https://github.com/w3c/csswg-drafts/issues/1774 is filed to track ways that the standard could be made more clear on these points.

First, we define computed::CSSPixelLength which contains a CSSFloat, a
pixel value, and then we replace computed::Length with CSSPixelLength.
Therefore, the |ComputedValue| of NoCalcLength, AbsoluteLength,
FontRelativeLength, ViewportPercentageLength, CharacterWidth, and
PhysicalLength is CSSPixelLength.
Besides, we drop NonNegativeAu, and replace computed::NonNegativeLength
with NonNegative<computed::Length>. (i.e. NonNegative<CSSPixelLength>)
Overhaul MallocSizeOf and related things.
This patch makes the MallocSizeOf stuff in Stylo work more like the HeapSizeOf
stuff already in Servo, except better. In particular, it adds deriving support
for MallocSizeOf, which will make it easier to improve coverage.
The patch does the following.
- Combines servo/components/style/stylesheets/memory.rs and the heapsize crate
into a new crate, malloc_size_of.
- Forks the heapsize_derive crate, calling it malloc_size_of, so that
MallocSizeOf can be derived.
- Both the new crates have MIT/Apache licenses, like heapsize, in case they are
incorporated into heapsize in the future.
- Renames the methods within MallocSizeOf and the related traits so they are
more concise.
- Removes MallocSizeOfWithGuard.
- Adds `derive(MallocSizeOf)` to a lot of types, in some cases replacing an
equivalent or almost-equivalent hand-written implementation.
- Adds stuff so that Rc/Arc can be handled properly.

**Do not merge yet.** This pulls in unrelated cssparser changes which add a dependency to `dota`, and we’d like to resolve https://github.com/dtolnay/dtoa/pull/9 before landing dtoa in mozilla-central. Also, the dependency change may require manually revendoring in mozilla-central.

stylo: Implement font feature values lookup
This PR reviewed by emilio and xidorn on bugzilla. That is backed out because of Windows build problems. Fixed and landing it again.
