[RFC 0/1] Implement AVR WDT (watchdog timer)

[Michael Rolnik]

1.  Initial implementation of AVR WDT
    There are two issues with this implementation so I need your help here
    a. when I configure the WDT to fire an interrupt every 15ms it actually 
happens every 6 instructions
    b. when I specify --icount shift=0 qemu stucks
