DOS: Make use of get/setAX and consorts instead of EmulatorGet/SetRegister(EMULATOR_REG_AX, ...). Start to implement real (but undocumented?) behaviour according to http://www.delorie.com/djgpp/doc/rbinter/ and http://www.datadoctor.biz/fr/data_recovery_programming_book_chapter6-pageXX.html (change XX by a valid page number) and http://spike.scu.edu.au/~barry/interrupts.html svn path=/branches/ntvdm/; revision=60778
