Instead of a tricky stack of enum iterators expose a `foreach()`
function on InlineFormattingContext, which takes a `FnMut`. This
prevents callers wanting to iterate from keeping a stack of iterators
and will potentially allow a future version of this function to avoid
borrowing the ArcRefCell<...> of inline boxes for every iteration
(presumably using something like OwnedRef).
Convert `inline_content_sizes` to use this new `foreach()` function and
move the `Computation` out of the function body to
`ContentSizesComputation`. This reduces the stack depth of inline size
computation, because `foreach()` is iterative and not recursive.
This is a preliminary change to removing the second round of text shaping
during layout, because shaping will use this new iterator.
* layout: Add *very* basic support for table layout
This is the first step to proper table layout. It implements a naive
layout algorithm, notably only taking into account the preferred widths
of the first table row. Still, it causes some float tests to start
passing, so turn on the `layout.tables.enabled` preference for those
directories.

PR #30974 integrated `servo/devices` repo into servo
codebase. `servo/devices` exposed the `bluetooth`
feature to conditionally compile native bluetooth
support for the target platform. In servo, this feature
is indirectly enabled via the `native-bluetooth` feature
exposed by `components/bluetooth`. When `servo/devices` was
integrated to servo, the conditional code was not updated
to use the `native-bluetooth` feature directly.

This is just a bit of code movement that trims down the size of the
`inline.rs` file in order to make it a bit more manageable. It leads the
way to more refactoring and cleanup in the future.
Despite the name of this dependency, it only handles bluetooth. Because
it's a separate repository. Integrating it, allows changes here to be
tested more consistently. In addition, it's likely that new bluetooth
libraries will allow removing the majority of the platform-specific code
in this directory.
This is based on the version of this dependency from:
https://github.com/servo/devices/pull/34
* layout: Implement support for `line-height` and `vertical-align`
This is an initial implementation of proper `line-height` and
`vertical-align` support. While this change includes the bulk of the
work there are still many missing pieces for full support. In particular
some big missing things are:
- Flex containers do not properly compute their baselines. The idea is
to tackle this in a followup change. This causes various flex tests
to start failing because everything used to be top aligned.
- The implementation of the line-height quirks (only active in quirks
mode) are incomplete. While the quirk works in many cases, there are
still some cases where it is handled incorrectly. This requires more
redesign and refinement, better suited for a followup.
- Most of the features are CSS 3 such as precision control of the
baseline and first and last baselines are not implemented. This
change gets us close to CSS 2.x support.
While there are many new test passes with this change some tests are
starting to fail. An accounting of new failures:
Tests failing also in Layout 2013:
- /css/css2/positioning/toogle-abspos-on-relpos-inline-child.html (only passes in Chrome)
- /css/CSS2/fonts/font-applies-to-001.xht (potentially an issue with font size)
Invalid tests:
- /css/CSS2/visudet/inline-block-baseline-003.xht
- /css/CSS2/visudet/inline-block-baseline-004.xht
- These are are failing in all browsers. See https://bugs.chromium.org/p/chromium/issues/detail?id=1222151.
Missing table support:
- /_mozilla/mozilla/table_valign_middle.html
Missing `font-size-adjust` support :
- /css/css-fonts/font-size-adjust-zero-2.html (also failing in 2013)
Incomplete form field support :
- /html/rendering/widgets/the-select-element/option-add-label-quirks.html (label isn't rendered so button isn't the right size in quirks mode due to line height quirk)
Need support for calculating flexbox baseline:
- /css/css-flexbox/fieldset-baseline-alignment.html
- /css/css-flexbox/flex-inline.html
- /css/css-flexbox/flexbox-baseline-multi-line-horiz-001.html
- /css/css-flexbox/flexbox-baseline-single-item-001a.html
- /css/css-flexbox/flexbox-baseline-single-item-001b.html
Failing because we don't create anonymous inline boxes for text children of blocks:
- /css/CSS2/linebox/anonymous-inline-inherit-001.html
Passes locally (potentially related to fonts):
- /css/CSS2/css1/c414-flt-fit-004.xht
- /css/css-transforms/transform-input-017.html
- /html/obsolete/requirements-for-implementations/the-marquee-element-0/marquee-min-intrinsic-size.html

Also update results.
- Upgrade the version of GStreamer for Windows
This upgrades the Windows build to use the most recent version of
GStreamer. This is necessary to upgrade our GStreamer dependency.
- Stop shipping GStreamer binaries on Linux
The binary bundle of GStreamer that we package is not used to compile --
only to run layout tests. It's too old for the APIs that we are using
(as evidenced by needed 1.18 for WebRTC) and nowadays Linux
distributions carry a new version so it's unecessary for our build
machines. No longer using this binary bundle will allow us to upgrade
our GStreamer dependency -- which now has stricter checks that we
are using at least version 1.18.
- Upgrade media to use newer versions of GStreamer / GLib dependencies

This dependency was forked in ##20641 in order to fix the Android build.
Years have gone by and it's quite likely that many things have changed
in the Android toolchain and these dependencies. We can sort out this
issue when getting the Android build working -- or if all else fails,
disable jemalloc for Android. In the meantime, unfork the dependency and
upgrade it.
Fixes#20645.

This adds support for fixing up tables so that internal table elements
that are not properly parented in the DOM have the correct box tree
structure according to the CSS Table specification [1]. Note that this
only comes into play when building the DOM via script, as HTML 5 has its
own table fixups that mean that the box tree construction fixups here
are not necessary.
There are no tests for this change. In general, it's hard to write tests
against the shape of the box tree, because it depends on the DOM. We
plan to test this via WPT tests once layout is complete.

This change adds support for `text-align-last` as well as ensuring that
it also applies to lines before forced line breaks. Two tests start to
fail because they rely on right-to-left text to pass:
- /css/css-text/text-align/text-align-last-010.html.ini
- /css/css-text/text-align/text-align-last-011.html.ini
The libunwind library version installed includes an rc number. The
latest released version of the `unwind-sys` crate doesn't handle this
properly, so rely on the latest commit in the upstream repository.
The code in script is written so that the document itself can move from
quirks to non-quirks mode, but this is never communicated to layout --
meaning quirky layout keeps happening. This is an issue when rewriting
the entire document with `document.write()` which is what some WPT tests
do to test quirks mode behavior.
hyper_serde changes very infrequently and typically only in order to
upgrade Servo dependencies. crates.io lists hyper_serde as having no
dependents, and its integration will not prevent releasing new versions.
Integrating it will both reduce the number of repositories we have to
maintain as well as making it easier to upgrade Servo dependencies.

This completes the transition to compiling Servo with rust stable. Some
nightly-only features are still used when compiling the `script` and
`crown` crates, as well as for some style unit tests. These will likely
break with newer compiler versions, but `crown` can be disabled for them
conditionally. This is just the first step.
This has some caveats:
1. We need to disable setting up the special linker on Linux. The -Z
option isn't supported with stable rust so using this is out --
meanwhile we can't be sure that lld is installed on most systems.
2. `cargo fmt` still uses some unstable options, so we need to rely on
the unstable toolchain just for running `fmt`. The idea is to fix this
gradually.
This data structure has all of the metrics needed to render a font and
is in `Au`. We'll need more of these metrics for implementing
`vertical-align` and its use doesn't increase the size of the Fragment
tree (as the BoxFragment is still larger). In addition, this will be
helpful when switching layout to `Au`.
This is the first part of constructing the box tree for table layout. No
layout is actually done and the construction of tables is now hidden
behind a flag (in order to not regress WPT). Notably, this does not
handle anonymous table part construction, when the DOM does not reflect
a fully-formed table. That's part two.
Progress toward #27459.
