    Turn resolution of trailing symlinks iterative everywhere · b356379a

    The last remaining place (resolution of nested symlink) converted
    to the loop of the same kind we have in path_lookupat() and
    path_openat().
    
    Note that we still *do* have a recursion in pathname resolution;
    can't avoid it, really.  However, it's strictly for nested symlinks
    now - i.e. ones in the middle of a pathname.
    
    link_path_walk() has lost the tail now - it always walks everything
    except the last component.
    
    do_follow_link() renamed to nested_symlink() and moved down.
