new structure for process management, structures to discuss
the idea behind kernel/include/progman.h was good but the implementation was
very not unix-like, so I made a new file under
kernel/include/process.h that will implement the same features
other changes:
- move usart register structs definitions outside of the device
- remove old build files
- delete boot.h and boot_loader.h (as they weren't used by anything)
- change on makefile to build binary with `makebin` instead of `xxd`
- new file memory.h to implement memory mapping and mmu control
- new type `uint` in types.h
