4e71684a3a LibWeb: Fix missing tokenizer state change in RCDATALessThanSign 
We can't RECONSUME_IN after we've used EMIT_CHARACTER since we'll have
returned from the function.

b59f4632d5 LibWeb: Unbreak character reference and DOCTYPE parsing post-UTF-8 
Oops, these were still using the byte-offset cursor. My goodness is it
unergonomic to index into UTF-8 strings, but Dr. Bugaev says it's good.

There is lots of room for improvement here. Just like the rest of the
tokenizer and parser. We'll have to do a few optimization passes over
them once they mature.

b6288163f1 LibWeb: Make the new HTML parser parse input as UTF-8 
We already convert the input to UTF-8 before starting the tokenizer,
so all this patch had to do was switch the tokenizer to use an Utf8View
for its input (and to emit 32-bit codepoints.)

19190267a6 LibWeb: Fix incorrectly consumed characters after reference tokens 
The NumericCharacterReferenceEnd tokenizer state should not advance
the input stream.

ca33bc7895 LibWeb: Fix tokenization of attributes with empty attributes 
We were neglecting to emit start tags for tags where the last attribute
had no value.

Also fix a parse error TODO that I hit while looking at this.

3c2fbc825c LibWeb: Call children_changed() on text nodes when flushing characters 
Now that we flush characters in a single place, we can call the Text's
children_changed() from there instead of having a goofy targeted hack
for <style> elements. :^)

c40de9275a LibWeb: Buffer text node character insertions in the new parser 
Instead of appending character-at-a-time, we now buffer character
insertions in a StringBuilder, and flush them to the relevant node
whenever we start inserting into a new node (and when parsing ends.)

a3936f10eb LibWeb: Fix tokenizing scripts with '<' in them 
The EMIT_CHARACTER_AND_RECONSUME_IN was emitting the current token
instead of the specified codepoint.

410fa5abe0 LibWeb: Parse barebones document without doctype, <html>, etc. 
Last night I tried making a little test page that had a bunch of <img>
elements and nothing else. It didn't work.

Fix this by correctly adding a synthesized <html> element to the
document if we get something else in the "before html insertion mode.

e5ddb76a67 LibWeb: Support "td" and "th" start tags during "in table body" 
This makes it possible to load Google Image Search results. You can't
see the images yet, but it's still something. :^)

8766e49a7c LibWeb+Browser: Use the new HTML parser by default 
You can still run the old parser with "br -O", but the new one is good
enough to be the default parser now. We'll fix issues as we go and
eventually remove the old one completely. :^)

db93db8100 LibWeb: Put whining about tokenizer errors behind an #ifdef 
Real web content has *tons* of tokenizer errors and we don't need to
complain every time as that makes the debug log unbearable.

f3b09ddd8e LibWeb: Implement more of the ScriptDataEndTagName tokenizer state 
Some of this is extremely repetitive. We'll need to rethink how we
do queue/emit to improve this.

8c96b8174b LibWeb: Handle AAA situation where there's no formatting element found 
In this case, we're supposed to return from the AAA and then jump to a
different behavior in the "in body" insertion mode. So now we do that.

e82226f3fb LibWeb: Handle two kinds of deferred script executions 
This patch adds two script lists to Document:

- Scripts to execute when parsing has finished
- Scripts to execute as soon as possible

Since we don't actually load scripts asynchronously yet (we just do a
synchronous load when parsing the <script> element for simplicity),
these are already loaded by the time we get to "The end" of parsing.

b9d5d45eff LibWeb: Handle an error condition for "a" start tag during "in body" 
If we have an <a> element on the list of active formatting elements
when hitting another "a" start tag, that's a parse error. Recover by
using the AAA.

c8e0426ab9 LibWeb: Parser should prefer the longest matchable HTML entity 
If we can match both "&copy" and "&copy;" we should prefer the latter.

Also remove invalid FIXME's about case insensitive entities.

1ef5d609d9 AK+LibC: Add TODO() as an alternative to ASSERT_NOT_REACHED() 
I've been using this in the new HTML parser and it makes it much easier
to understand the state of unfinished code branches.

TODO() is for places where it's okay to end up but we need to implement
something there.

ASSERT_NOT_REACHED() is for places where it's not okay to end up, and
something has gone wrong.

2b1517f215 LibWeb: Add all branches from the parsing spec to "in body" 
This makes us crash in TODO() more often, but it's better that we know
what's missing instead of incorrectly ending up on the fallback path.
