LibC: Implement freopen, rewind and fix bugs in code
...
Now everything will be properly locked once threads are implemented.
All functions "lock" the stream for the wanted operation

LibC+userspace: Make everything compile with -Wall -Wextra -Werror
...
I added -Wall -Wextra -Werror as public compile flags to libc. Now
everything in userspace in compiled using these flags. I made all
necessary changes to allow compilation to work.
Only exception is execvp which has a large stack usage. Maybe it
should use malloc for the buffer but posix allows ENOMEM only when
kernel is out of memory... This can be fixed when fexecve is
implemented and there is no need for absolute path.

LibC: cleanup and fix fgets
...
My quick fix for fgets wrote non-nullterminated newline if size was
one.
POSIX doesn't specify what happens if size == 0, so I do the same as
glibc and return NULL without setting errno.

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 :)

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

This is now handled on the libc side. There might be reasons to

to libc for now :)
