winedos / Fix reboot vector

[Jukka Heinonen]

This fixes those DOS programs that want to exit via reboot.
As far as I know, int19 under Windows NT DOS subsystem
works like ExitProcess so that was fixed, too.





Changelog:
  Reboot (int19) under DOS now does ExitProcess.
  Made BIOS reboot vector call int19.
