This uses ICU for all of the Intl.PluralRules prototypes, which lets us
remove all data from our plural rules generator.
Plural rules depend directly on internal data from the number formatter,
so rather than creating a separate Locale::PluralRules class (which will
make accessing that data awkward), this adds plural rules APIs to the
existing Locale::NumberFormat.
This uses ICU for the Intl.NumberFormat `format` and `formatToParts`
prototypes. It does not yet port the range formatter prototypes.
Most of the new code in LibLocale/NumberFormat is simply mapping from
ECMA-402 types to ICU types. Beyond that, the only algorithmic change is
that we have to mutate the output from ICU for `formatToParts` to match
what is expected by ECMA-402. This is explained in NumberFormat.cpp in
`flatten_partitions`.
This lets us remove most data from our number format generator. All that
remains are numbering system digits and symbols, which are relied upon
still for other interfaces (e.g. Intl.DateTimeFormat). So they will be
removed in a future patch.
Note: All of the changes to the test files in this patch are now aligned
with both Chrome and Safari.
Note: We keep locale parsing and syntactic validation as-is. ECMA-402
places additional restrictions on locales above what is required by the
Unicode spec. ICU doesn't provide methods that let us easily check those
restrictions, whereas LibLocale does. Other browsers also implement
their own validators here.
This introduces a locale cache to re-use parsed locale data and various
related structures (not doing so has a non-negligible performance impact
on Intl tests).
The existing APIs for canonicalization and display names are pretty
intertwined, so they must both be adapted at once here. The results of
canonicalization are slightly different on some edge cases. But the
changed results are actually now aligned with Chrome and Safari.
If we get a suggestion from fontconfig, we try those fonts first, before
falling back on the hard coded list of known suitable fonts for each
generic family.
This saves us the trouble of maintaining our own implementation,
and instantly brings us to full WOFF2 feature parity with others.

GC-allocated objects should never have JS::SafeFunction/JS::Handle
fields.
For now the plugin only emits warnings here, as there are many cases
of this occurring in the codebase that aren't trivial to fix. It is also
behind a CMake flag since it is a _very_ loud warning.
Download files to a temporary location, then only move the downloaded
file to the real location once the download is complete. This prevents
CMake from being confused about partially-downloaded files, e.g. if
someone presses ctrl+c in the middle of a download.
Note the GN build already behaves this way.
We already have required this version for quite a while for Lagom,
Ladybird and Serenity. Now that we require it in all of our CMakeLists,
let's scrub for better ways of writing things.
On macOS, it's not trivial to get a Mach task port for your children.
This implementation registers the chrome process as a well-known
service with launchd based on its pid, and lets each child process
send over a reference to its mach_task_self() back to the chrome.
We'll need this Mach task port right to get process statistics.
JPEG2000 is the last image format used in PDF filters that we
don't have a loader for. Let's change that.
This adds all the scaffolding, but no actual implementation yet.
And add a verification step to the emoji data generator to ensure all
emoji are listed in this file. This file will be used as a sources list
in both the CMake and GN build systems.
It is probably possible to generate this list. But in a first attempt,
the CMake code to set the file as a dependency of a pseudo target, which
would then parse the file and install the listed emoji was getting quite
verbose and complicated. So for now, let's just maintain this list.
