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. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

LibHTML: Add DocumentFragment Right now this is just a simple ParentNode subclass with its node type being DOCUMENT_FRAGMENT_NODE.

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: Move everything into the Web namespace

LibWeb: Move get_element_by_id() to a NonElementParentNode mixin class This matches the current version of the DOM spec. And since C++ doesn't have mixins this is actually a CRTP class.

LibWeb: Maintain a mapping for fast lookup in getElementById() With this change we maintain a data structure that maps ids to corresponding elements. This allows us to avoid tree traversal in getElementById() in all cases except ones when lookup happens for unconnected elements.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.

LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

GC_DECLARE_ALLOCATOR(DocumentFragment);
LibWeb: Implement <template> parsing Note that there is currently no way to display them as we can't currently clone nodes. Adds special case for templates for dumping to console. Doesn't add it to the DOM inspector as I'm not sure how to do it.
