Make blockdev pointers 32 bits This allows us to break through the 64K limit for includes CFS in zasm, a limit we were dangerously close to breaking. In fact, this commit makes us go over that limit. Right in time!

shell/stdio: decouple from blkdev (again) Move load/save to blkdev_cmds and add a new "poke" builtin shell cmd that is the mirror of "peek" and strictly uses stdio (no blkdev involved). This allows us to slim the minimal OS size but, more importantly, change the behavior of "load" so that we don't expect GetC to block until Z is set. This way, using "load X" with X being larger than the blkdev size won't block forever. This also brings our RC2014 minimal kernel below the 1K mark again.
