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: Add simple definition for realloc
...
The syscall just crashes the kernel currently. I will implement
this when needed

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 :)

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 :)

Kernel/LibC: add free function for FixedWidthAllocator

I have to rework the syscall API and allocators in process. For
now this works well enough :)

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.
