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

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

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 :)

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 :)
