* avrdude interface for Atmel STK500V2 programmer
*
* As the AVRISP mkII device is basically an STK500v2 one that can
* only talk across USB, and that misses any kind of framing protocol,
* this is handled here as well.
*
* Note: most commands use the "universal command" feature of the
* programmer in a "pass through" mode, exceptions are "program
* enable", "paged read", and "paged write".
