328f44814e 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!

af2c561c6b zasm: begin erroring out reliably
Up until now, invalid source input had undefined behavior. We're now
beginning to define that behavior so that zasm can be a bit more usable.

bc1496a7e3 zasm emul: bring back kernel/user distinction
It was a bad idea to remove it. Now that I'm introducing the concept of
a per-app glue file, it becomes much easier to build emulated zasm as a
userspace app.

7fad3b0c90 Move /parts/z80 to /kernel
Let go of that "meta os" thing. it's not as meta as I made it sound
like. It's a kernel.

28d5ebdc8a Make apps folder into a namespace
To straighten out includes and to pave the way into zasm being part of
the same "include CFS" as parts, we make zasm includes namespaced.
