Kernel/LibC: add free function for FixedWidthAllocator
...
I have to rework the syscall API and allocators in process. For
now this works well enough :)

Kernel: Add basic fixed width allocator for userspace
...
We have to move process stacks to the general heap and maybe map
kernel to higher half.

Kernel: remove message from BAN::Error
...
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.
We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.

BuildSystem: Fix header copying to sysroot
...
We used to copy all headers everytime to sysroot which caused
rebuild of the whole os. Now we use the cmake command
'copy_directory_if_different' which seemed to fix this issue :)

BuildSystem: We are now using cmake instead of plain make
...
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.
I wanted to rewrite the whole build system and changed to using cmake
