Track HTTPFallback state more thoroughly
https://bugs.webkit.org/show_bug.cgi?id=279683
rdar://problem/135962595
Reviewed by Alex Christensen.
Currently the HTTPFallback state is mostly maintained in the web process where
we make decisions about upgrading the request. This works okay for simple
failure conditions, but we need a way to remember the fallback state in the
UIProcess when a site uses multiple redirects and navigations. We also need to
ensure we don't upgrade same-site navigations.
This patch resolves these issues by tracking the HTTPFallback state in the
PageLoadState, and I use it to know whether we should show the HTTPS browsing
warning. Without this information, we should repeatedly show the warning
because we didn't remember that the user consented to loading the http URL.
This change also uses the currently committed document's URL to decide if we
are performing a same-site navigation. If that is the case and that document
was loaded with HTTP, then we don't want to optimistically upgrade the request.
