patch #7688: Implement parent programmers feature

* avrdude.conf.in: updated documentation comment and some programmers 
    have now parents
  * config_gram.y: initpgm will now called at first use of programmer 
    in main. parser sets only the function pointer in the pgm structure.
    Pin and pin lists definitions can now be empty to remove the parents
    setting.
  * doc/avrdude.texi: updated documentation
  * main.c: added call to pgm->initpgm after locate_programmer
  * pgm.[hc]: added field initpgm in structure, added function pgm_dup
