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

to make the sync operation synchronous.

Kernel/LibC: remove PATH resoltion from kernel
...
I have no idea why I had made PATH environment variable parsing
to be part of the kernel. Now the shell does the parsing and
environment syscall is no longer needed.

Kernel/LibC: add flag to enable/disable sse support

SSE support is very experimental and causes GP. I decided to make
SSE not default until I get to fixing it :)

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.

This allows file and directory permissions work as intended.
cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

LibC: make printf buffer only 128 bytes
...
Only reason for it to be big is if you want super large zero padding
for your number. This will eventually be handled without the buffer.

LibC: we don't parse syscall arguments in unistd
...
We just call Kernel::syscall() with 5 arguments from the variadic function.
This was a necessary addition since the syscall() function
used over 2 KiB of stack space.

Kernel: Userspace signal handlers are now called one at a time
...
I added a syscall for telling the kernel when signal execution has
finished. We should send a random hash or id to the signal trampoline
that we would include in the syscall, so validity of signal exit can
be confirmed.
