this when needed

Bananymous 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 :)

Bananymous cae0a1cc60 LibC: add working f modifier to printf

takes more than 1024 characters (either super large number or very
big percision).

Also we dont handle NaN and infinity cases

Bananymous 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

Bananymous 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 :)

now this works well enough :)

Bananymous 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.
