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.

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.

But we're still at a certain distance from assembling it with zasm:
we're busting the 0x100 symbol limit.

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.

Strip comments out of code before packing CFS
...
This shrinks the CFS size to 21k from nearly 64K. This will allow me to
kick the can down the road a bit with regards to supporting storage
seek/tell greater than 64K.
I'll get to it, but first, I want to assemble zasm with zasm!
