9a72f10221 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.

22e990ed89 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.

73c3fc7947 shell/stdio: decouple from blkdev (again) 
Move load/save to blkdev_cmds and add a new "poke" builtin shell cmd
that is the mirror of "peek" and strictly uses stdio (no blkdev
involved).

This allows us to slim the minimal OS size but, more importantly, change
the behavior of "load" so that we don't expect GetC to block until Z is
set. This way, using "load X" with X being larger than the blkdev size
won't block forever.

This also brings our RC2014 minimal kernel below the 1K mark again.

2e8af376e3 pgm: new kernel module 
The pgm module implements a shell hook so that when an unknown command
is typed, we look into the mounted filesystem and look for a file with
the same name as the command. If we find one, we load it in memory and
run it.

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

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.

ff99062d5b Move RC2014 recipe in its own folder 
Also, remove `parts/platforms`. It makes no sense. Only recipes make
sense.
