This more concrete wrapper type can write a prefix the very first time something
is written to it. This allows removing plenty of useless monomorphisations caused
by the former W/SequenceWriter<W> pair of types.
Improve LRU cache behavior in SelectorFlagsMap
This code used to insert duplicate entries to avoid expensive shuffling of the LRU cache. With uluru this is no longer necessary, because reordering the cache is cheap.
Now it uses the `LRUCache::find` method from uluru 0.2 to update entries in-place. This should increase cache hits by eliminating unnecessary evictions.
This PR also updates `arrayvec` because `uluru` depends on it, and `immeta` because it depends on `arrayvec`.

This introduces DeclarationSource, to see if a declaration has been parsed or
set from CSSOM in a declaration block.
The Servo_DeclarationBlock_SetFoo and similar callers are changed to
DeclarationSource::CssOm because their semantics are more CSSOM-y, but it
shouldn't matter since they should all be checked before hand with
Servo_DeclarationBlock_PropertyIsSet.
… rather than the start location of the current construct.
This likely places the error just *after* of the unexpected token
whereas before would be best, but that’s likely a much bigger change.

I'm about to introduce more state here to implement optimizations for custom
property cascading, so this abstraction is useful to encapsulate that state.
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.

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:
https://bugzilla.mozilla.org/show_bug.cgi?id=880831
This patch changes servo to preserve and expose this value for use in M-C.

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.

We replace Au with CSSPixelLength for the length part of
computed::CalcLengthOrPercentage. Therefore, it would be easier to use
CSSPixelLength for all other LengthOrPercentage{*} types.
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>)
Now that rust-cssparser reports 1-based locations, bump the required
cssparser version and remove get_location_with_offset. Previously,
some code paths were not calling get_location_with_offset; see
https://bugzilla.mozilla.org/show_bug.cgi?id=1398869 for some
background.
