This adds basic support for `text-transform` in a way that is more
complete than legacy layout. There are still many missing elements of
proper `text-transform` support such as:
1. Support for `full-width` and `full-size-kana`
2. Support for grapheme based uppercasing, lowercasing, and
capitalization. These are all done per-code point right now.
3. Support for the language-specific `SpecialCasing.txt` cases for case
mapping such as the ones for Irish and Turkish.

This reverts the Rust edition updates to these three traits as well as
incorporates https://phabricator.services.mozilla.com/D117887. The
purpose of this change is to reduce the diff with upstream stylo.
Finally, formatting is disabled for these crates as well.
This deviates from css2, but it's mandated by css-align, and matches
what other browsers do when no margin is 'auto'.
When some margin is 'auto', this should keep the proper round-tripping
behavior that Gecko and WebKit lack, and Blink recently adopted.
This adds support for table rows, columns, rowgroups and colgroups.
There are few additions here:
1. The createion of fragments, which allows script queries and hit
testing to work properly. These fragments are empty as all cells are
still direct descendants of the table fragment.
2. Properly handling size information from tracks and track groups as
well as frustrating rules about reordering rowgroups.
3. Painting a background seemlessly across track groups and groups. This
is a thing that isn't done in legacy layout (nor WebKit)!

This is part of the preparation for splitting stylo into a separate
crate. We have made various changes to selectors includings:
1. Bumping the rust edition
2. Fixing typos and updating links

selectors we seem to have missed in the process of updates.

* ./mach fmt
* Fix comment length
* Split out button init, update spec comments
* Move gamepad event handling from document to global
* Map and normalize axes/button values
* Use std::time for gamepad timestamp
* Adjust gamepad handling in event loop
* Move button press/touch check into map+normalize function
- Small change but is more in line with spec
* ./mach fmt
* Update comment spec links and warning messages
* Doc comments -> regular comments
* Add window event handlers for gamepad connect/disconnect
* Adjust gamepad disconnect behavior
* Add missing TODO's, adjust gamepad/gamepadbutton list methods and formatting
* Update button handling from gilrs, add comments
* Enable gamepad pref during WPT tests and update expectations
* Update WPT expectations in meta-legacy-layout
In order for stylo to be a separate crate, it needs to depend on less
things from Servo. This change makes it so that stylo no longer depends
on servo_url.
This is part of getting Servo using an version of style closer to
upstream. This change reverts some changes we made to `to_shmem` and
`to_shmem_derive` in order to reduce our diff with upstream stylo.
This moves white space collapse to right before breaking and shaping
happens, which is more similar to what happens in legacy layout. This is
the first step toward making this procedure more efficient (avoiding
string copies) and also implementing support for `text-transform`.

In layout2020, 'list-style-position' is disabled behind a pref, so the
list_style_position field is an Option.
The serialization of the 'list-style' shorthand wasn't correctly
handling the case of it being None.
This adds an initial implementation of font fallback, on part with the
one used in legacy layout. There are still issues. For instance, font
matching is done per unicode character rather than based on graphemes or
the shape first approach of Chrome. The idea is that these changes can
be made later.

This implements a very naive row height allocation approach. It has just
enough to implement `vertical-align` in table cells. Rowspanned cells
get enough space for their content, with the extra space necessary being
allocated to the last row. There's still a lot missing here, including
proper distribution of row height to rowspanned cells.

This should fix issues that we have with Float16 support on newer LLVM.
This also updates style, in order to remove the duplicate version of
bindgen. We will soon be able to manage updates to style more
consistently.
For example,
style.cssText = "margin: 1px 2px 3px 4px";
[...style];
will now be
["margin-top", "margin-right", "margin-bottom", "margin-left"]
instead of
["1px", "2px", "3px", "4px"]
Instead of using the border widths from the style, use the ones recorded
by the `BoxFragment`. This is necessary because inline layout can
override these border widths during fragmentation. For instance, when a
box is split across two lines only one fragment should have an inline
start border.
The crash when loading servo.org happens in the JIT code
emitted by SM's CacheIRCompiler to invoke the VM function
`ProxyGetPropertyByValue`.
To disable this code path, it is not sufficient to disable
just the baseline JIT (which exposed in servo under the
pref `js.baseline.enabled`) but also the baseline
interpreter which is controlled by a different flag in SM.
This PR disables renames the `js.baseline.enabled` pref in
Servo to `js.baseline_jit.enabled` and introduces a new
pref `js.baseline_interpreter.enabled` that controls the
baseline interpreter.

Instead of tracking justification opportunities during line layout, wait
until the line is about to be laid out and justification is about
happen. This makes the logic for tracking justification opportunities
simpler. In particular, we no longer have to carefully adjust them when
trimming whitespace. Additionally, this avoids a bit of work unless
justification is turned on.
This also includes a small cleanup of the justification code.
This change starts collecting the starting baseline set for fragments,
which is necessary for some layout modes (flex and tables, namely) as
well as being important for the implementation of `align-items`. In
addition, it converts baseline measurement to use `Au` everywhere.

Instead of making the client set up GL video decoding, have this done
inside libservo. The details necessary for decoding are fetched via
Surfman now. This also removes the setup for the context on Android --
which has no GStreamer support now anyway. In the future, this could be
enabled, but should likely be done using Surfman, instead of passing on
all these details manually.

The new strategy for dependencies with upstream in Gecko is to manage
them in separate repositories, which will more easily allow rebasing our
changes on top of newer Gecko work.
