Virgil Dupras 289037a3dd lib/parse: make parseDecimal "tail" HL

the last read character.

Virgil Dupras cc754e12aa parseExpr --> parseExprDE: easy ones 
Those replacements were trivially equivalent. For the other ones, an
examination of the context is necessary.

Virgil Dupras 381d57a513 basic: make variable A the only input variable 
Mechanism for assigning inputs to the specified variable is clumsy and uses
binary space. Always using A is much simpler and doesn't seem very limiting to
me. I do that because there's many more "input" commands I'd like to add.

shell.

Virgil Dupras b7d4860acf basic: add in/out commands 
Also, fixed the cmd matching algo to not accept partial matches. For example,
to stop matching "input" when the command was "in".

Virgil Dupras 1cea6e71e0 basic: add a print cmd 
It can only print a decimal literal. But still, that's a big step because
I hadn't implemented decimal formatting yet.

Virgil Dupras 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.

Virgil Dupras cdd0b64570 Modify userspace .org and RAMSTART expectations 
Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be
set in all userspace glue code. This gives us more flexibility with regards to
how we manage that.

Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to
the end of the binary, which is adequate in a majority of cases.

Will be useful for my upcoming mega-commit... :)

Virgil Dupras 7cf3ed38da Extract str.asm from core.asm and make core included by userspace 
Most of register fiddling routines (which is now the only thing contained
in care.asm) are used by almost all userspace apps, often in inner loops.

That makes the penalty of using jump tables for those a bit too high.
Moreover, it burdens jump tables needlessly.

Because this unit is very small (now that string routines are out), it makes
sense to always include it in binaries.

Virgil Dupras 8d46895dd3 lib/parse: decimal ending with a whitespace are now valid 
Also, make empty strings be parsed as invalid by parseDecimal.
