Allow HTML serializer to output HTML5 DOCTYPE
For https://bugzilla.gnome.org/show_bug.cgi?id=747301
Use simple HTML5 DOCTYPE for about:legacy-compat
HTML5 uses a DOCTYPE without a PUBLIC or SYSTEM identifier. It looks
like this:
<!DOCTYPE html>
I can't use XSLT to output this, because to get a DOCTYPE I have to
provide a PUBLIC or SYSTEM identifier. Luckily, the standards folks
recognized this and provided this semantically equivalent form for the
HTML DOCTYPE:
<!DOCTYPE html SYSTEM "about:legacy-compat">
But people don't like seeing the "legacy" identifier in their output.
They'd rather see the shiny new DOCTYPE. Since we know that
about:legacy-compat is defined by the W3C to be semantically equivalent
to the sans-SYSTEM DOCTYPE, we could just special-case it in the HTML
serializer in libxml2. So if you set the SYSTEM identifier to
"about:legacy-compat", you get an HTML5 short-form DOCTYPE.
