This should fix the following two "expected to fail" tests:
- getComputedStyle(elem) for url() listStyleImage uses the resolved URL
and elem.style uses the original URL
- getComputedStyle(elem) for url() listStyle uses the resolved URL
and elem.style uses the original URL
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.
