Kernel: Rework whole Terminal structure
...
Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

Kernel: Rewrite whole device structure
...
We now have DevFileSystem which is derived from RamFileSystem. All
devices are RamInodes. We don't have separate DeviceManager anymore.
To iterate over devices, you can loop througn every inode in devfs.

Kernel: TTY now unblocks semaphore after read
...
This allows concurrent reads not fully reading the buffer not block
indefinately.

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

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
