We convert ComputedOperation::{Accumulate, Interpolate}Matrix into gecko type
not on the main thread, so we cannot use nsCSSValueList_heap (which is not
thread safe so we cannot create it and destroy it on different threads).
Therefore, we use nsCSSValueSharedList to represent the cloned
from_list/to_list. In this patch, we also implement the reversing way,
i.e. Convert eCSSKeyword_{accumulate, interpolate}matrix into
{Accumulate, Interpolate}Matrix.
If we set the composite operation to accumulate, we may need to accumulate two
mismatched transform lists, and then to interpolate them. In order to
accumulate two mismatched transform lists, we also need the reference
box information, so use the same idea as that for interpolation. i.e.
use AccmulateMatrix to store it temporarily, and convert it into matrix
later.
We use this arm to store the interpolated result of two mismatched
transform lists, and we resolve it until we know the reference box size
(on Gecko side). The conversion from ComputedOperation::InterpolateMatrix
to eCSSKeyword_interpolatematrix will be implemented later in this patch series.
Stop parsing @supports rules before Delimiter::Bang
Fixes#15482
Shorthand parsing uses `parse_entirely`, so we have to ask it to stop before the `!important`.
An alternate fix is to not use `parse_entirely` there and ensuring that all callers of `PropertyDeclaration::parse_into()` check that the input is exhausted. Two of the three callers do that anyway because they check for `!important`.
We also weren't checking for the end of the parser for `CSS.supports()`.

Parent mismatch should not clear style sharing cache.
We can have cousins in the cache whose parent doesn't match ours, and other
cousins whose parent does. When we encounter one of the former, that's not a
reason to stop lookin for the latter.

Bump euclid to 0.13 and heapsize to 0.4
This is necessary for the serde 1.0 update.

Without this patch anim-css-strokewidth-1-by-pct-pct.svg (and possibly
others) fails because we calculate the result as 'calc(0px + 10%)' and
we don't support calc on stroke-width (yet) so the rendered result is
incorrect.
As a more thorough fix, we should make the zero-value for
LengthOrPercentageOrNumber a zero *number* (instead of a zero length)
but that won't work yet since we don't support animating between
stroke-widths with units and those that don't (see
https://bugzilla.mozilla.org/show_bug.cgi?id=1369614). Regardless of
that, we still shouldn't introduce calc in order to add a zero value
using the LengthOrPercentage type, so this change is still needed.
style: Split stylesheets.rs
This file has become quite bloated lately. This commit deletes that file in
favor of a set of submodules.
The only noticeable change apart from code move, is converting deep_clone_foo
methods into a trait.
It also unifies logic related to different style rules in the same place.
There's some missing work, specially related to font-face and counter-style, but
I think this is worth landing in the meantime.
