stack_top got changed into a char, because `extern void` isn't even valid. others are self-explanatory

2021-07-17basic boot module supportdzwdz
This loads a file from the boot disk into memory. Currently it just gets printed, but it's going to become a real executable soon.

2021-07-10abstract away loggingdzwdz
Now, the kernel only interfaces with the architecture dependent stuff via functions declared in generic.h. I'll write a linter enforcing this soon.
2021-07-10a sensible source structuredzwdz
The idea is that src/kernel/ is only allowed to interface with the hardware using whatever's defined in src/arch/generic.h. I'll probably write a small script for checking this later on. This is a giant commit so I've probably fucked something up. It boots fine on Bochs and QEMU, so at least there's that.
