There are numerous bugs and security vulnerabilities due to first-letter / RenderTextFragment being so exotic to the rest of render objects.  We should make RenderTextFragment act like the rest of rendering objects.  Namely, it should own regular children instead of holding a special pointer for first-letter.

This will fix almost all crashes and bugs related to first-letter in WebCore/editing.
