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 :)

67005a80be LibC: add working f modifier to printf 
This is implementation will write out of bounds if the conversion

Also we dont handle NaN and infinity cases

d5ce4c9d2c 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
