Specifically:
For "bullets", i.e. 'list-style-type:disc|circle|square|
disclosure-closed|disclosure-open', we use a built-in font
(-moz-bullet-font, which has glyphs for those symbols + space) to
retain mostly backwards compatible rendering for those. Authors may
override that with an explicit 'font-family' ::marker style though.
We also use this font for 'list-style-image' in case it would
fallback to one of the above when the image fails to load (so that
we get the same width space).
When the -moz-bullet-font is used we also set 'font-synthesis' to
avoid synthesizing italic/bold for this font. Authors may override
this with an explicit ::marker declaration.
We also set 'letter-spacing' and 'word-spacing' to the initial value
for bullets for web-compat reasons. Again, authors may override
this with an explicit ::marker declaration. (This breaks backwards-
compat slightly but makes us compatible with Chrome. We used to
ignore these for list-style-type:<string> too.)

Otherwise we assert due to the styles being different from the cached
ones, but it doesn't matter as these don't influence Gecko scrollbars.

This results in lots of new WPT test passes.
There were also a couple of WPT tests that turned out to be broken;
tab-size-inline-001 and -002 had errors in their reference files such
that they'd never pass anywhere. So those are fixed here.
Depends on D117331

So we update d property in the style system as well. This makes sure we
have the correct computed style and the correct rendering result.

Support fit-content for preferred size, min size, and max size. This
patch only implement the style system. For layout part, we will do that
in the following patches.

Those can't be ordered at specified / computed value time, since the
percentage basis could be negative.
Needs tests of course, running through try atm.

This prevents incorrectly reusing cached results when the contents go
away and new contents are allocated with the same address.
Note that these keep alive transitively everything else under them, so
all other medialist keys don't need this.
By making this a proper hashmap it should also improve cache lookup
times if the cache grows too big.

They are not. The serialization code already checks if the result is
empty, which can happen for other reasons. This makes the code a bit
more resilient to misuse.

We'd like to start offering servo nightly builds
with layout 2020 engine so that users can test
the new layout without building servo. These new
builds will be offered in addition to the current
2013 builds until we switch over to 2020 as the default.

This moves more members to the CompositorDisplayListInfo struct, which
now holds all miscellaneous, non-WebRender data when sending display
lists. It also documents what each things sent with a display list does.

Add a compositor-side scroll tree
This will allow the compositor to properly chain scrolling requests up
when a node has reached the extent of the scroll area. In addition, it
removes the use of the deprecated WebRender `scroll()` API. This fixes
scrolling on servo.org.

De-dupe phf
<!-- Please describe your changes on the following line: -->
Update phf to 0.10 in the `script` and `selector` crates to remove the dupe and only use 0.10. `phf` actually has a 0.11 version but we'll need an update to `markup5ever` to be able to pick it.
This removes 9 crates from a Linux debug build.
