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.

93e40aeb09 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!

556be3f0ce zasm: allow for whitespace inside string literals 
Also, increase scratchpad size. It wasn't big enough for some
expressions in shell unit.

013a3b74c8 Add the concept of unit tests 
Will be much much easier to tests new core routines without having to
re-create their context first.

Also, extract parse.asm from core.asm

23f0dc18ca 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.

22c7eeaa5d Move apps/zasm/tests to tools/tests/zasm 
This 'apps' folder is going to disappear. Everything is going to be a
"part" to be assembled through recipes. 'apps' has no meaning.

34ee91a0d7 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.
