Soundness issue with base::Error

base::Error type contains public field named ptr. With this definition, it is possible to create a base::Error with an invalid pointer and trigger memory safety errors such as use-after-free or double-free with safe Rust.

The users of xcb crate are advised not to manipulate the field.
