Rework of bitbanging functions setpin, getpin, highpulsepin to make simplier use of new pindefs data in pgm structure

Browse Source 
* linuxgpio.c, bitbang.c, buspirate.c, par.c, pgm.h, term.c, serbb_*.c: changed 
	  interface of setpin, getpin, highpulsepin to take pin function as parameter 
	  (not the real number, which can be found by pgm->pinno[function])
