Shrink code by using registers for variables "length" and "address"
http://code.google.com/p/optiboot/issues/detail?id=33 Fix high-value watchdog timeouts on ATmega8 http://code.google.com/p/optiboot/issues/detail?id=38 Change "start app on bad commands" code to start the app via the watchdog timer, so that the app is always started with the chip in fully reset state. http://code.google.com/p/optiboot/issues/detail?id=37 (cherry picked from commit 6f7687b0f925cb07447cbbcc692766c51c02f700)
