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

Bananymous d5ce4c9d2c LibC: add probably functional *printf

pointer. We can use this to implement all the printf family

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 :)
