This ensures that a generated C++ method called `register` will have an
underscore appended to it, avoiding a compile error.

This is a special form of `<string>` so doesn't need its own style value
type. It's used in a couple of font-related properties. For completeness
it's included in ValueType.

This matches the name in the CSS Typed OM spec. There's quite a lot
still to do to make it match the spec behavior, but this is the first
step.
(cherry picked from commit 76daba3069de4c184c6b2317d0c89b50f81a8c00)
When a property is a "legacy name alias", any time it is used in CSS or
via the CSSOM its aliased name is used instead.
(See https://drafts.csswg.org/css-cascade-5/#legacy-name-alias)
This means we only care about the alias when parsing a string as a
PropertyID - and we can just return the PropertyID it is an alias for.
No need for a distinct PropertyID for it, and no need for LibWeb to
care about it at all.
Previously, we had a bunch of these properties, which misused our code
for "logical aliases", some of which I've discovered were not even
fully implemented. But with this change, all that code can go away, and
making a legacy alias is just a case of putting it in the JSON. This
also shrinks `StyleProperties` as it doesn't need to contain data for
these aliases, and removes a whole load of `-webkit-*` spam from the
style inspector.
(cherry picked from commit fdcece2e88b91b9ec6cf63c3466525fb77540316;
amended to:
* resolve a conflict on height: in getComputedStyle-print-all.txt
* run prettier on CSSGeneratedFiles.md)
Instead of switching on the PropertyID and doing a boatload of
comparisons, we reorder the PropertyID enum so that all inherited
properties are in two contiguous ranges (one for shorthands,
one for longhands).
This replaces the switch statement with two simple range checks.
Note that the property order change is observable via
window.getComputedStyle(), but the order of those properties is
implementation defined anyway.

Previously we were assuming that the attribute return value was never
nullable and going to be returned in an Optional<IntegralType>, causing
complile errors for something such as: `attribute unsigned long?`.

Mirroring the pre-existing `generate_from_integral` function. This will
allow us to fix a bug that all of these if statements have in common -
no handling of nullable types.
This also adjusts the type casted for each integral to fully match that
stated by the spec.

USVString attributes Now replace any surrogates with the replacement
character U+FFFD and resolve any relative URLs to an absolute URL. This
brings our implementation in line with the specification.
(cherry picked from commit 335d51d6782c66e7743d773f6f6b6a32a2cb2067)
USVString is defined in the IDL spec as:
> The USVString type corresponds to scalar value strings. Depending on
> the context, these can be treated as sequences of either 16-bit
> unsigned integer code units or scalar values.
This means we need to account for surrogate code points by using the
replacement character.

For a long time, we've used two terms, inconsistently:
- "Identifier" is a spec term, but refers to a sequence of alphanumeric
characters, which may or may not be a keyword. (Keywords are a
subset of all identifiers.)
- "ValueID" is entirely non-spec, and is directly called a "keyword" in
the CSS specs.
So to avoid confusion as much as possible, let's align with the spec
terminology. I've attempted to change variable names as well, but
obviously we use Keywords in a lot of places in LibWeb and so I may
have missed some.
One exception is that I've not renamed "valid-identifiers" in
Properties.json... I'd like to combine that and the "valid-types" array
together eventually, so there's no benefit to doing an extra rename
now.

amended to remove half of the changes. Many of them were in
ladybird-only code. Changed commit message.)
C++ will jovially select the implicit conversion operator, even if it's
complete bogus, such as for unknown-size types or non-destructible
types. Therefore, all such conversions (which incur a copy) must
(unfortunately) be explicit so that non-copyable types continue to work.
This is `counter(name, style?)` or `counters(name, link, style?)`. The
difference being, `counter()` matches only the nearest level (eg, "1"),
and `counters()` combines all the levels in the tree (eg, "3.4.1").

Following the rules in the algorithm from
https://webidl.spec.whatwg.org/#js-platform-objects, "To Internally
create a new object implementing the interface interface", this change
incorporates the steps to load a prototype from new.target, and write
it to the created instance returned from constructor_impl(). This
mirrors the code for generate_html_constructor(), which incorporates
additional steps needed by Custom Elements.

the second commit of https://github.com/LadybirdBrowser/ladybird/pull/86)
The Encoding specification maps ISO-8859-1 to windows-1252 and expects
the windows-1252 translation table to be used, which differs from
ISO-8859-1 for 0x80-0x9F.
Other contexts expect to get the actual ISO-8859-1 encoding, with 1-to-1
mapping to U+0000-U+00FF, when requesting it.
`decoder_for_exact_name` is introduced, which skips the mapping from
aliases to the encoding name done by `get_standardized_encoding`.

Methods and attributes marked with [FIXME] are now implemented as
direct properties with the value `undefined` and are marked with the
[[Unimplemented]] attribute. This allows accesses to these properties
to be reported, while having no other side-effects.
This fixes an issue where [FIXME] methods broke feature detection on
some sites.

This allows searching for text with case-insensitivity. As this is
probably what most users expect, the default behavior is changes to
perform case-insensitive lookups. Chromes may add UI to change the
behavior as they see fit.
