Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information.

LibHTML: Add an empty CSS parser.

#pragma once
#include <AK/NonnullRefPtr.h>
LibWeb: Added simple parsing for (at)import rules For now, the parsing is very crude, and parses only the document url. The meta queries for the import are ignored.

#include <AK/String.h>
LibWeb: Split CSS::StyleSheet into StyleSheet and CSSStyleSheet This is a little convoluted but matches the CSSOM specification.

LibWeb: Add context to new CSS parser, and deprecate the old one The new one is the same as the old one, just in the new Parser's source files. This isn't the most elegant solution but it seemed like the best option. And it's all temporary, after all.

LibWeb: Don't tolerate unit-less lengths (except 0) in standards mode "width: 500" is not a valid CSS property in standards mode and should be ignored. To plumb the quirks-mode flag into CSS parsing, this patch adds a new CSS::ParsingContext object that must be passed to the CSS parser. Currently it only allows you to check the quirks-mode flag. In the future it will be a good place to put additional information needed for things like relative URL resolution, etc. This narrows <div class=parser> on ACID2 to the correct width. :^)

LibWeb: Move DOM classes into the Web::DOM namespace LibWeb keeps growing and the Web namespace is filling up fast. Let's put DOM stuff into Web::DOM, just like we already started doing with SVG stuff in Web::SVG.

LibWeb: Make CSS::Selector reference counted The end goal is to make the PseudoClass::not_selector be a Selector instead of a String that is repeatedly re-parsed. But since Selector contains a Vector of ComplexSelectors, which each have a Vector of SimpleSelectors, it's probably a good idea to not be passing them around by value anyway. :^)

RefPtr<CSS::IdentifierStyleValue> parse_line_style(const CSS::DeprecatedParsingContext&, const StringView&);
LibWeb: Add CSS property 'border' This makes it possible to write shorter CSS. Instead of writing .foo { border-width: 3px; border-style: solid; border-color: blue; } it is now possible to write .foo { border: 3px solid blue; } while the order of values is irrelevant. Currently only the basic values are supported. More values should be added in the future. Three more value specific parse functions were added: parse_line_width, parse_color, and parse_line_style Additionally a few test cases were added to borders.html.

RefPtr<CSS::StyleValue> parse_html_length(const DOM::Document&, const StringView&);
LibWeb: Add a dedicated function for parsing HTML length values Presentation attribute lengths (width, height, etc.) can always be unit-less (e.g "400") so going via the normal CSS parsing path only works when the document is in quirks mode. Add a separate parse_html_length() that always allows unit-less values.
