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
