Cleanup pass on the dirtree infrastructure, in preparation for making rm -r

handle infinite depth. Fix docs, tweak dirtree_handle_callback() semantics,
remove dirtree_start() and don't export dirtree_handle_callback(), instead
offer dirtree_flagread(). (dirtree_read() is a wrapper around dirtree_flagread
passing 0 for flags.)
