Errors and events should include their 32-bit sequence number

Currently, XCB hands errors and events back to the caller exactly as they were read off the wire. This should be changed to hand back an additional four bytes with the full 32-bit sequence number. For compatibility with XCBGenericReply and Xlib's xReply/xEvent/xError, I'd like to add this new field after the raw bytes.
