ServoStyleSetSizes now has two uses, one for the Stylist, and one for the UA
cache, and so the patch removes 'Stylist' from the field names.

Measure ImageValue objects (take 2).
We have about 11,500 of these when loading gmail in a Stylo-enabled build, from
SpecifiedUrls; the objects themselves account for about 1.3 MiB of memory, and
the strings within them about 2.9 MiB.
We also have a very small number of them on the Gecko side.

`MallocSizeOfOps::enclosing_size_of_op` is an `Option<>` type, and the panic in
question is caused by not providing a value in a case where it's needed for
measuring a HashSet.
HashMaps and HashSets are common enough that it makes sense to make
`enclosing_size_of_op` non-optional, which this patch does.
This avoids grabbing the document when values that inherit from the body,
whatever that means, aren't under the body.
In that case we'll get a semi-random value, but that's also mishandled by Gecko
anyways (and probably Blink, though haven't tested), and doesn't really make
much sense.
Preserve sourceURL comment on style sheets
In addition to the sourceMappingURL comment, there is a second special
comment, "sourceURL", that can be used to set the "display name" of a
style sheet for developer tools. This name is also used as the base
URL for the source-map URL resolution algorithm. sourceURL is
described here:
https://blog.getfirebug.com/2009/08/11/give-your-eval-a-name-with-sourceurl/
The devtools feature bug is here:

This patch changes servo to preserve and expose this value for use in M-C.

Share specified URLs with Gecko
This makes use of our Arc offset machinery to allow Gecko to store Arc<String> values and ensure there are used appropriately.

This patch changes servo to preserve and expose this value for use in M-C.
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>)
stylo: Store location information for keyframe rules.
So far, we only store location info for the whole Keyframes block, not for each
of the keyframe rule. Without this info, the devtool can't present the rules
on the devtool panel properly.
In this patch, we collect the source location info while parsing keyframe selector.
The binding function, Servo_KeyframesRule_GetKeyframe, is also fixed (and renamed
to Servo_KeyframesRule_GetKeyframeAt to match the fix) to accept line and column
parameters from Gecko, so we can pass/set them with the source location from Servo.
This is the servo part of [Bug 1394994](https://bugzilla.mozilla.org/show_bug.cgi?id=1394994).
