libdraw: add Cursor2, a 32x32 high-res cursor
Also add setcursor2, esetcursor2, and draw protocol encoding. Calls to the old setcursor, esetcursor create a 32x32 by pixel doubling when needed.
Add the #goo to allow use in C++.
Silence a few more warnings. Strip down the mkfiles more. Fix bug in X11 mouse handling, note groups.
