Remove deprecated TreeVisitor
This type and its associated methods has been deprecated for a while now. Time to remove it. Applications can use a TreeWalk instead to access the elements of any tree-like object. Change-Id: I047e552ac77b77e2de086f63cb4fb318da57c208 Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
