8fb5f97a18 Kernel: Improve open() POSIX compatability 
Also rename Process::sys_creat -> create_file since it is not
actually a syscall and only used by open as a healper.

39a5c52088 Kernel: Fix directory permissions 
We did not care about X bit in directories and instead used only the
R bit for search/read.

323de3c866 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.

1fa7a1cac4 Kernel: Add basic HPET support to replace PIT if exists 
This works same way as the PIT implementation; calls Scheduler every
milli second.
