- Make int09 update the BIOS data segment's keyboard status flags

Browse source 
bytes, implement pause key handling.
- Let int16/02 read the keyboard status flags bytes instead of calling
  GetAsyncKeyState().
- Make the keyboard state buffer used for Get*Key*() reflect
  VK_L/RMENU properly.
- Small fixes.
