Reimplement ShmPutImage.

There's no reason to not just dispatch this straight into the GC.  As a
bonus, if you do so, damage wraps correctly, and thus swcursor works.
The side effect is it's no longer possible to override ShmPutImage with
ShmRegisterFuncs().

Also remove the (broken) damage tracking for same from EXA, since it didn't
work right, and is now superfluous.
