Move /emul/forth/* to /emul Less noisy this way

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...

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.

emul: build boot binary in one pass ... instead of building boot.fs, and then z80c.fs/icore.fs in separate passes. This strengten xcomp by making it support 2 completely separate dicts (that is, the X dict is *not* connected to the system dict. The chain now stops at EXIT def in boot.fs).

# z80c.bin is not in the prerequisites because it's a bootstrap
# binary that should be updated manually through make updatebootstrap.

stage1: stage.c $(OBJS) forth0-bin.h
$(CC) stage.c $(OBJS) -o $@
forth: add bin dict compilation stage! Big one. This allows us to write higher order words directly in Forth, which is much more convenient than writing post-immediate (see "NOT" structure in diff if you want to see what I mean) structures in ASM. These structures can then be written to ROM (rather than loaded in RAM for definitions loaded at run-time). That's quite a bit of tooling that was added, 2 compilations stages, but I think it's well worth it.

forth: improve execution model My approach with RS was slightly wrong: RS' TOP was always containing current IP. It worked, but it was problematic when came the time to introduce RS-modifying words: it's impossible to modify RS in a word without immediately messing your flow. Therefore, what used to be RS' TOS has to be a variable that isn't changed midway by RS-modifying words. I guess that's why RS is called *return* stack...
