style: Distinguish between the tree structures used for traversal and selector matching.

This patch renames TNode::parent_element to traversal_parent, since it returns
the parent from the perspective of traversal (which in Gecko uses the
flattened tree).  It also renames TNode::children to traversal_children
for the saem reason.

We keep parent_element and children functions on TNode to use for selector
matching, which must be done on the real DOM tree structure.
