faf14b880e 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 :)

cae0a1cc60 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

49fe3d0d4f 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

ff2e2937a5 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 :)

12e42f40c5 Kernel/LibC: add free function for FixedWidthAllocator
I have to rework the syscall API and allocators in process. For
now this works well enough :)

bcfd838131 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.

aa2aee684b 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.

781cc78a1f 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 :)
