* avrdude.conf.in: fixed buff pins of avrftdi programmers (low active buffer need now inverted numbers)
* avrftdi*.*: accept also old libftdi (0.20 still works with it), added powerup to initialize
* ft245r.c: accept libftdi1, code cleanup and make it more similar to avrfdti (os they might be merged someday)
