LibC: add wait and waitpid

Note that wait() doesn't work since only waiting for specified
pid is supported. wait() will just return -1 and set errno to
ECHILD.

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 :)

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 :)
