Fixing compile issues and booting for gcc and clang, and fixing warnings from -Wall & -Wextra. Mainly to get back into this project, and get it working for development on more systems.

Notes:
- There are probably other errors not shown here, either under -Wpedantic or on other OSes like the BSD's. But hopefully this clears up most of them and helps building & booting.
I will go through and fix most of the -Wpedantic errors at a later date, maybe when the filesystem is done.
