BuildSystem: using sysroot doesn't need root privileges anymore!
...
Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.

Kernel: Add some functionality to disable TTY input/output
...
Userspace programs can call tty_ctrl() to disable/enable tty from
handling input and displaying output.
This API is probably going to change in the future to ioctl calls
but I'm not sure how ioctl is used and what functionality should it
have. I decided to create whole new function and syscall for now.
Next I will expose framebuffer in /dev/fb0 and then I can start work
on graphical environment! :D

Kernel/LibC: userspace malloc now uses mmap to get memory
...
We could remove syscalls to allocate more memory. This was not
something the kernel should have done.

Kernel/LibC: add mmap for private anonymous mappings
...
This will be used by the userspace to get more memory. Currently
kernel handles all allocations, which is not preferable.

BuildSystem: use -a with rsync
...
This allows cmake to not rebuild whole project every time

BuildSystem: Base sysroot is now distributed as a tar ball
...
This allows file and directory permissions work as intended.
cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Kernel/LibC: Add bareboness signals

You can now call raise() to raise a signal. Signal handlers are
not yet supported, but the handling works :)

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 :)

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

BuildSystem: Fix header copying to sysroot
...
We used to copy all headers everytime to sysroot which caused
rebuild of the whole os. Now we use the cmake command
'copy_directory_if_different' which seemed to fix this issue :)

BuildSystem: We are now using cmake instead of plain make
...
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.
I wanted to rewrite the whole build system and changed to using cmake
:)
