a19376df6c Copy ACIA driver to blkfs 
We can get rid of acia.z80, but not of acia.fs yet, we still need it.

7a0e63746f parse: don't validate 0x and 0b lengths 
It doesn't serve much purpose and takes up many precious bytes. And,
after all, parsed didn't do it either...

a2d89de557 drv/sdc: implement core words in z80 
In addition to making the driver significantly faster, it allows us
to make SDC port configuration opaque to sdc.fs.

d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT 
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

019d05f64c Make the shell a userspace app 
That's my mega-commit you've all been waiting for.

The code for the shell share more routines with userspace apps than with kernel
units, because, well, its behavior is that of a userspace app, not a device
driver.

This created a weird situation with libraries and jump tables. Some routine
belonging to the `kernel/` directory felt weird there.

And then comes `apps/basic`, which will likely share even more code with the
shell. I was seeing myself creating huge jump tables to reuse code from the
shell. It didn't feel right.

Moreover, we'll probably want basic-like apps to optionnally replace the shell.

So here I am with this huge change in the project structure. I didn't test all
recipes on hardware yet, I will do later. I might have broken some...

But now, the structure feels better and the line between what belongs to
`kernel` and what belongs to `apps` feels clearer.

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.
