feat(huge): huge refactor (in progress).

Commented out libc includes to uncover all explicit dependencies.
A large fraction has now been ported over (no testing).
I did not port over the command line tools, such as the rc shell.
These will be done independently - as of now I just want the library to
stand independent.

Compilation currently fails due to the lack of math functions.
