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... :)

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.
