Browse Source 
* doc/avrdude.texi,avrdude.1: added doc for linuxgpio 
	* avrdude.conf.in: added template for linuxgpio programmer
	* config_gram.y: pin numbers restricted to [PIN_MIN, PIN_MAX]
	* pindefs.h: added PIN_MIN, PIN_MAX, removed unused LED_ON/OFF
	* configure.ac: configure option enable-linuxgpio, print of enabled options
	* linuxgpio.[ch]: new source for linuxgpio programmer
	* Makefile.am: added linuxgpio to sources list
	* pgm_type.c: added linuxgpio to programmer types list
