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.

Let go of that "meta os" thing. it's not as meta as I made it sound
like. It's a kernel.

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!

zasm emul: add tooling for includes fsdev
...
On build, pack `parts/z80` into a CFS and embed it into the emulated
zasm executable as an fsdev. This will allow for the upcoming include
directive to have something to go to.
For now, this is useless except for inflating the emulated zasm's size.

zasm: use blkdev IDs as input and output
...
This will soon allow use to seek and tell on input, which is necessary
for a second pass which is necessary for forward symbol references.
This require making `blkSel` a bit more flexible. Rather than having one
global selected blkdev, each app can select its own, in its own memory
space.
