Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
FIXME addressed in open method:
10. If async is false, the current global object is a Window object,
and either this’s timeout is not 0 or this’s response type is not the
empty string, then throw an "InvalidAccessError" DOMException.
This is the way.
On a more serious note, there's no reason to keep adding ref-counted
classes to LibWeb now that the majority of classes is GC'd - it only
adds the risk of discovering some cycle down the line, and forces us to
use handles as we can't visit().
The XHR gives us a set of conditions where XHR objects must survive
garbage collection, even when there are no pointers to them on the heap.
This patch implements those conditions using the new cell
self-protection mechanism in LibJS.
This allows us to use this:
```cpp
auto header = TRY_OR_RETURN_OOM(realm,
Infrastructure::Header::from_string_pair(name, value));
```
Instead of the somewhat unwieldly:
```cpp
auto header = Infrastructure::Header {
.name = TRY_OR_RETURN_OOM(realm, ByteBuffer::copy(name.bytes())),
.value = TRY_OR_RETURN_OOM(realm, ByteBuffer::copy(value.bytes())),
};
```
This changes the signature of LoadRequest::set_body() to take by value
and then use move semantics to move the contents of the ByteBuffer.
This is done to avoid the fallible copy constructor of ByteBuffer.
The intent is to use these to autogenerate prototype declarations for
Window and WorkerGlobalScope classes.
And the spec links are just nice to have :^)
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

Let's stop putting generic types and AOs from the Web IDL spec into
the Bindings namespace and directory in LibWeb, and instead follow our
usual naming rules of 'directory = namespace = spec name'. The IDL
namespace is already used by LibIDL, so Web::WebIDL seems like a good
choice.
Unlike ensure_web_prototype<T>(), the cached version doesn't require the
prototype type to be fully formed, so we can use it without including
the FooPrototype.h header. It's also a bit less verbose. :^)
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.
