Add infrastructure for :before and :after in DOM
https://bugs.webkit.org/show_bug.cgi?id=103705
Patch by Elliott Sprehn <esprehn@chromium.org> on 2012-12-05
Reviewed by Eric Seidel.
Add all infrastructure for reimplementing generated content :before and
:after as DOM Elements. Now ElementRareData has two pointers to PseudoElements
for the generated content and Node has methods for traversing the tree
including generated content.
This will allow the generated content to be treated as real nodes instead
of anonymous and take part in the usual recalcStyle and attach flow which
fixes many bugs and vastly simplifies the ifecycle of generated content.
Instead of attempting to land both the infrastructure and enable it at
the same time which has proven problematic due to how drastic this change
is, this patch contains only the support code so a much smaller future
patch can be used to switch it on.
No new behavior, this is just the infrastructure.
