Add lots of consts.
In general, we should use 'const fz_blah' in device calls whenever the callee should not alter the fz_blah. Push this through. This shows up various places where we fz_keep and fz_drop these const things. I've updated the fz_keep and fz_drops with appropriate casts to remove the consts. We may need to do the union dance to avoid the consts for some compilers, but will only do that if required. I think this is nicer overall, even allowing for the const<->no const problems.
