zasm: includes CFS is now built on-the-fly by zasm.sh
...
This makes for a much more usable zasm linux binary that doesn't have to
be rebuilt every time apps or kernel change.

Parametrize zasm linux bin's include CFS file
...
... instead of embedding it in the binary itself. Additionally, add a
"zasm.sh" wrapper to faciliate zasm calls on a linux machine.

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.

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.
