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

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

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

to libc for now :)
