Problem: crash when passing invalid buffer to undotree()
Solution: Use get_buf_arg() instead of tv_get_buf_from_arg().

Problem: undotree() only works for the current buffer
Solution: Add an optional "buffer number" parameter to undotree(). If
omitted, use the current buffer for backwards compatibility.
