Create new pin definition data structures to support 0-based pin numbers, and mixed inverse/non-inverse pin lists. 

* avrftdi.c,buspirate.c,linuxgpio.c,par.c,serbb_*.c: added function call 
          to fill old pinno entries from new pin definitions.
	* pindefs.[hc]: added data struct and helper functions for new pin definitions
	* avrdude.conf.in: pins in entries using ftdi_syncbb are now 0-based
	* config_gram.y: allow combinations of inverted and non-inverted pins in pin lists
	* ft245r.c: reworked to work directly with the new pin definitions,
          pins are now 0-based, inverse pins are supported, buff is supported
	* pgm.[ch]: added new pin definitions field to programmer structure, 
          adapted pin display functions
