Bananymous f79250c4d4 LibC: Rewrite all the headers. 
We now have more or less posix issue 2018 conforming libc headers.

This was a really time consuming and boring operation but it had to
be done.

Now we get to actually start implementing libc :)

Bananymous 67005a80be LibC: add working f modifier to printf 
This is implementation will write out of bounds if the conversion
takes more than 1024 characters (either super large number or very
big percision).

Also we dont handle NaN and infinity cases

Bananymous d5ce4c9d2c LibC: add probably functional *printf 
I wrote a general printf function that takes an putc function
pointer. We can use this to implement all the printf family
functions. I haven't done thorough testing with this, but it seems
to be functional for the most part

Bananymous 1cf7ef3de6 Kernel: Remove offset from OpenFileDescriptor 
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

Bananymous 2fe9af7165 Kernel/LibC: add free function for FixedWidthAllocator 
I have to rework the syscall API and allocators in process. For
now this works well enough :)

Bananymous ff5bcd4416 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.

Bananymous 8d6db168d6 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.

Bananymous c660df14ec 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 :)

Bananymous e49d3c7bfe 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

:)
