Kernel: Rework syscall calling
...
I removed the intermediate function when calling syscalls. Now syscall
handler calls the current process automatically. Only exception is
sys_fork, since it needs a assembly trampoline for the new thread.

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 :)

We now create the TTY as soon as possible so we can show console

Kernel: kernel doesn't allocate large blocks of data on stack
...
We used to allocate 1 KiB blocks on multiple places on stack. This
is a problem, since kernel stack shouldn't have to be too big

TTY is now a file that you can read from/write to. I still have
to port shell to use this new interface
